    Beschreibung: The present work appertains to a series of investigations in the field of trophodynamics of water bodies conducted by the department of hydrobiology ”Mosrybvtuza” under the leadership of Prof. Director N.S. Gaevska. Usually with quantitative collections of benthos ostracoda are hardly taken account of. But with the employment of special methods it is possible to be convinced that they are encountered in massive numbers. The role of ostracods in the nutrition of fish is recognised as important by many authors. On the question of the feeding of ostracods, in the literature there are only the fragmentary indications about the occurrence in the gut of ostracods of algae (diatoms, desmids) and detritus. The study of the feeding of ostracods was conducted both by the method of dissecting the guts of ostracods taken from natural waters, and by the method of feeding ostracods under laboratory conditions with a variety of food objects. Moreover, with a view to revision of obtained quantitative data, for determination of food requirements of ostracods the respiration method was applied.

    Beschreibung: Viruses, which are characterised by a relative simplicity of chemical composition, are involved with all the groups of the animal and plant world. The discovery of viruses of lower organisms has special interest. Along with the already known viruses lysing bacteria and actinomycetes, viruses have been discovered in recent years which lyse algae. During investigations of water from water-bloom patches and of mud taken from zones of massive accumulation of blue-green algae in the Dneprovsk reservoirs, the authors obtained viruses lysing algae. The revealing of viruses producing lysis of blue-green algae, which one could use in the control of water-blooms, has the greatest interest. With this aim, samples of water were collected from various zones of water-bloom patches in the Kremenchug, Dneprovsk and Kukhov reservoirs. For viruses lysing algae we propose the name 'algophages'. Along with the existence of viruses of algae of the phage type, one cannot deny the possibility of the existence of viruses of another type, multiplying in the cells of algae and causing their virus illnesses.

    Beschreibung: Many have observed the reduction of the quantity of zooplankton in the presence of water blooms. It is known that in seas zooplankton as it were avoids places of accumulation of blue-green algae. By observations on one of the tributaries of the Rybinsk reservoir - the River Shumorovka - the authors tried by simultaneous collections to trace the changes in numbers, not only of zoo- and phytoplankton but also of bacteria. The plankton was collected by quantitative nets with suitable numbers of gauze and bacteria were taken account of by the method of direct calculation on membrane filters. It can be seen that the development of blue-green algae appears as an important factor, determining not only the intensity but also the direction of the process of production of zooplankton.

    Beschreibung: Many sides of the biology of Polyphemus pediculus are adequately studied at the present time. Most complicated is the question of its feeding. Dissection does not give an idea of the composition of the food, since Polyphemus strongly grinds its food with its mandibles. For clarification of the composition of the food of Polyphemus pediculus, the authors carried out in July and August 1962 a series of experiments with the application of radio-carbon methods in order to judge the degree of utilization of one or other foods by the quantity of C14, accumulated in the body of the crustacean after feeding. Particular attention in these experiments was given to the question of the possibility of the utilization by polyphemus of plant food - bacteria, algae and detritus.

    Beschreibung: The original method, proposed by Yentsch (1957), of determination of chlorophyll directly in the cells, attracts attention by its simplicity. In order to measure the content of chlorophyll by this method, a determined volume of suspension of algae is filtered through a membrane filter. The latter is dried a little, clarified by immersion oil, clamped between two glasses, and spectrophotometrized. Extinction is read off at , wavelengths equal to 670 millimicrons (around the maximum absorption of chlorophyll a in the cell) and 750 millimicrons (correction for non- specific absorption and dispersion of light by particles of the preparation). The method of Yentsch was employed by the authors for determination of chlorophyll-a in samples of phytoplankton. They conclude that in spite of the simplicity and convenience of determination the method must be applied sufficiently carefully. It is more suitable for analysis of cultures of algae, where, non-specific absorption of light is insignificant.

    Beschreibung: The rhythm of division of 9 species belonging to different groups of algae were analysed in situ and in the laboratory. The research which developed in different environmental conditions attempted to establish the capacity for multiplication and assimilation of chlorophyll on the part of the algae under study with a view to placing them in a culture. The results obtained showed that the green multicellular algae (eg. Ulothrix) and the blue algae (eg. Lyngbya, Oscillatoria) are able to produce an appreciable quantity of dry matter, just as the unicellular algae. At the same time it arises that amongst the numerous factors of the environment, temperature plays one of the most important roles in the process of multiplication.

    Beschreibung: The purpose of this work is a contribution to the quantitative record of the use of iron by planktonic algae. Preliminary experiments with Chlorella to determine the rate of iron intake in the presence of inorganic sources of iron did not produce the desired result. The crucial point of this work is the investigation of the influence of various external factors on the stability of FeEDTA (FeEDTA = Ferric(III)-compound of ethylene-diamine tetra-acetic acid), since this compound appears to be particularly well-suited as a source of iron for planktonic algae (e.g. TAMIYA et al. 1953). Cultures of Chlorella fusca in a light thermostat were used in experimental research. Methods and results are discussed.

    Beschreibung: The reaction of Mn(II) with water-dissolved oxygen, to a higher manganese hydroxide in an alkaline medium, as with the longstanding classic Winkler method, is the first step in the method described here. The assumption for faultless results by the conventional and modified Winkler method is clean water, which contains no organic substances by Mn(III) or Mn(IV). In many cases, however, eg. in river and lake-water tests, it can be seen with the naked eye that after some time the originally brown-coloured precipitate of manganese hydroxide becomes more and more colourless. Oxygen content was analysed in the water samples and evaluated by raising the amount of the leuko-base and giving the corresponding dilution of the colouring matter solution formed still higher oxygen contents can be measured.

    Beschreibung: By the industrial cultivation of blue-green algae, there very much appears the important question about their carbon nutrition. Spirulina grows within the range of pH value of medium of 8.5 - 11.0. In this range of pH value in the culture medium CO2 is present in the form of bicarbonate and carbonate, which serves as principal source of carbon for the present type of algae. There is little information yet about the influence of the pH of the medium, and the form of carbon components of the medium, on the rate-increase of Spirulina. Investigations were conducted into the influence of some pH values of medium on the rate-increase of the alga Spirulina platensis.

    Beschreibung: There is no doubt that determination of the biomass of zooplankton (primarily of crustaceans) will be taken into consideration in practice and limnological works, especially after the recent publication of fairly comprehensive tables of weights of a whole range of species of freshwater copepods and cladocerans. The usefulness of applying formulae of determining the biomass of marine crustaceans for freshwater copepods is discussed.

    Beschreibung: The best evidence for establishing the level of eutrophy of a water-body is its algal production which makes it possible to identify the type and the intensity of the eutrophication according to the kind and number of algal species present: when the number of algae exceeds half a million per litre then one speaks o an ”algal bloom”. The scope of the present research aims to verify if the alga Selenastrum capricornutum can be used as a test alga under our culture conditions and to determine the eutrophic level of the secondary effluent of a modern plant for the treatment of domestic discharge and to investigate the eventual ”limiting factors”. Finally this paper aims to study the effect on the secondary effluent of tertiary treatment carried out artificially in the laboratory.

    Mechanism of red colouration in Tovel-See (”Conclusions” only) [Translation from: Archiv fur Hydrobiologie 38 299-302, 1941] (2021)

    Beschreibung: Cases of red colouration in small lake basins, due to the abundant appearance of microorganisms have long been known. Usually it is caused by a fast, sudden, intensive propagation (so called ”bloom”) of Cyanophycae and bacteria. (e.g. Oscillatoracae, thiobacteria etc.). An exception to this is the red colouration of Tovel-See, an alpine lake basin in the Dolomites of the Brenta group (Trentino), lying at a height of 1178 m and hidden in the woodland of a valley. Here the red bloom has a double rhythm: a daily and a yearly rhythm. The colouration of one part of the lake takes place in the warmest months of the year (i.e. July, August, September) and in the middle hours of the day. The immediate origin of the bloom has been known for a long time: it is caused by the Peridinacae Glenodinium sanguineum. This paper describes the phenomenon of red colouration of the lake and discusses its conditions.

    Beschreibung: Species of Pithophora occasionally appear in Europe and are associated mostly with the tropical, higher water plants, cultivated in numerous botanical gardens. In June 1973 pale green, branched threads were discovered in the pond of the Wroclaw Botanical Garden, amongst filaments of Spirogyra crassa (Kutz.) Czurda emend. and Cladophora glomerata (L.) Kutz. floating on the water surface. They were maintained for several weeks in crude cultures and produced numerous, dark akinetes tightly packed with reserve material. This collected material was found to be a member of the family Pithophora, Wittr. Further examinations identified the material as Pithophora oedogonia. The findings point out that it is probable, that species of Pithophora Wittr. can become acclimatized in Europe, primarily in ponds of botanical gardens, where consequently they are able to tangle easily with higher tropical plants.

    Beschreibung: From research carried, out on a section of the Levriere, concretions (granules, nodules, which were sometimes joined together) partly covering the river ”bottom” were observed. The authors propose to make besides a petrographic examination of the calcareous precipitations and to see if their origin is connected to a biological activity, or if it is purely a case of a physical-chemical precipitation. The hydrological background of the Levriere, a small river of the Normandy Vexin, is given and conditions of the formation of the concretions studied.

    Beschreibung: The proximate composition and amino acids assay of smoked Clarias gariepinus and Oreochromis niloticus were determined using standard procedures. The mean proximate composition of Oreochromis niloticus are 8.9% moisture, 16.00% lipids, 5.6% ash, 44.5% crude protein, 0.42% crude fiber and 24.9% NFE while Clarias gariepinus has 8.19% moisture, 15.55% lipids, 4.725 ash, 40.46% crude protein, 0.50% crude fiber and 30.58% NFE. There is therefore a nutrient variation between the 2 species of fish Oreochromis niloticus has higher crude protein, lipids, moisture and ash content than Clarias gariepinus.The amino acids profile shows that both fishes have 17 amino acids. Apart from Tryptophan, the following essential amino acids Histidine, Methionine, Threonine, Isoleucine, Leucine, Lysine, Valine and Phenylalanine are present in both fish. Oreochromis niloticus however has higher quantities of the essential amino acids except for Histidine than Clarias gariepinus

    Beschreibung: The evaluation of Cr. Cu, Mn, Fe, Ni, Zn,As and Pb concentrations in Clarias gariepinus and Oreochromis niloticus from Lake Geriyo Yola,Adamawa, Nigeria using X - ray fluorescence (XRF) technique is discussed. The analytical samples are irradiated with high energy electrons of 109Cd to produce fluorescent X-rays was produced which passes to the Silicon-lithium detector through Mo target as a source of monochromatic X-rays. The spectrum of energy generated on the detector was processed by a Multi- Channel Analyzer to obtain analytical data. The intensity of the fluorescent X-rays on the detector is proportional to the concentration of the individual element of interest in the sample. This method can identify up to 30 or more elements at the same time. The results showed varying levels of heavy metals in the fishes. The concentrations of Cr, Mn, Cu, and Ni in the fishes were much higher than WHO and PEPA maximum permissible limits, while the concentrations of Zn and Pb were lower than the standards. The results suggest that the lake is polluted with Cr, Mn, Cu and Ni and the consumption of fishes of the lake is life threatening to man.

    Beschreibung: Tilapia guineensis eggs were spawned and hatched in different salinities (17, 12, 7, 5, 2 and 0) ppt. The study was conducted in eight replicates. The aim of the investigation was to ascertain disparity in hatching size of Tilapia guineensis attributable to salinity. Immediately hatching was observed, body weight of five hatchlings in each replicate was individually weighed in milligramme. The individual total length of the five hatchlings was also measured in millimeter. The height of the yolk sac larva was determined with micro-metre screw gauge graduated in millimeter from the top of the yolk sac to the dorsal region of the larva. Data obtained were used to calculate yolk sac volume. Significant differences (P〈0.01) were observed in body weight and total length of larvae hatched in different salinities. The heaviest and longest larvae were hatched in 12 ppt saline water. The yolk sac volume of larvae hatched in lower salinities were significantly higher (P〈0.01) than the yolk sac volume of larvae hatched in higher salinities. The smallest yolk sac volume was recorded in 12ppt saline water. Our findings show that salinity could be manipulated for economic production of heavier seeds of Tilapia.

    Beschreibung: The culture of oysters, clams, scallops, and other molluscs is collectively one of the fastest growing sectors of the aquaculture industry. An inherent issue with shellfish culture methods, particularly for off-bottom culture (i.e. floating trays, racks, long lines, strings, rafts), is biofouling. This can occur directly, by biofouling of the animals themselves, or indirectly, by fouling of cages, nets, filters, and other equipment. Problematic biofouling species have been identified and segmented into six groups: algae, barnacles, mussels, tubeworms, ascidians and hydroids. Controlling and mitigating biofouling can result in significant costs for commercial shellfish culture operations.

    Beschreibung: This study focused on the assessment of Terminalia suparba (bark, leave and root) based diet to improve the ovulation of Clarias gariepinus brood stocks. Ten female and ten male brood stocks were obtained from a reputable fishfarm in Ogun State, Nigeria and were fed with the diets for four weeks before the breeding exercise. The latency period observed in treatments 1 to 4 was 4hours 30minutes while the ovulation period in treatment 5 was 8 hours. There was no significant different (P〉0.05) among the means. The brood stocks in Treatment 2 (Root) has the highest fecundity count (2001) while those in Treatment 5 (control) has the least fecundity count (1496). The phytochemical analysis of the plant materials showed the presence of Alkaloids, Tannin, Phenol, Glycoside, Flavonoids, Steroids, Phlobatannin, Saponin, Anthraquinones. The physical and chemical parameters of water observed showed that dissolved oxygen value ranges from 3.28 -4.60, pH 6.5 - 8.5, temperature 28.0 - 28.8 and conductivity 8.9 - 9.20. It is therefore concluded that the inclusion of Terminalia suparba in the feed of Clarias gariepinus broodstock will not only improve ovulation but also reduce the latency period.

    Beschreibung: One of the priority research projects of the Nigerian Institute for Oceanography and Marine Research (NIOMR) is broodstock development and mass propagation of silver catfish, Chrysichthys nigrodigitatus of which the broodstock is naturally abundant in New Gala River. Selected physical characteristics and water physico-chemical parameters of the upper reach of the New Calabar River at Aluu were investigated. The highest depth value of 9.20 m was recorded in the middle of the river. The width of the river measured during spring high tide and low tide were 174 m and 110 m respectively. The cross-sectional area and average flow velocity of the river were 797.13 m2 and 0.374 m/s respectively. The discharge of the river was computed as 298.13m3/s. The river water was acidic most of the period (Hydrogen ion concentration, pH: 5.12 to 7.43), with low total alkalinity values (4.00 to 12.00 mgCaCO3/L) and low total hardness values (11.5 to 51.2 mgCaCO3/L) which indicate that the river water is black and soft. There was significant (p~,0.05) seasonal variation in temperature (23.1 to 31.7~'C\}, Secchi transparency (9.30 to 19.00 cm), total hardness (11.5 to 51.2 mgCaCO3/L), dissolved oxygen (5.20 to 7.50 mg/L) and dissolved oxygen deficit (0.02 to 2.95mg/L). These results are useful for several stake holders who use the river as a sink for trade wastes, as source of water for fish farming, as source of broodstocks of Chrysichthys nigrodigitatus, as raw water for water treatment plants, and as means of transportation of industrial materials.

    Beschreibung: This study looked into the physicochemical and bacteriological investigation of fish and water in Aiba Reservoir. Water and fish samples collected were studied to assess their bacteriological and physicochemical characteristics and their suitability for domestic purposes. Structural questionnaires were administered to the fishermen around the reservoir and experiments were carried out in the laboratory to analyze the samples. The results showed that the total viable bacteria count was high(1.02 x 105 cfu/ml) while few Staphylococcus aureus and E. coli occurred insignificantly. The population of S. aureus and E. coli in the fish gills, liver and tissue were insignificant. The results obtained from the physicochemical analysis of the water samples showed that the reservoir has optimum water temperature of 29degreesC ~c 0.25, a pH of 7.70 ~c 0.20, dissolved Oxygen level of 7.20mgO2/1 ~c 0.20 and total hardness of 45.00 mg/ICaC03 ~c 1.05. The microbial load in the fish sample is higher than that in the water sample. Further strict hygienic measures and surveillance is recommended so as to improve the water quality and to avoid deleterious effects on the health of the Iwo inhabitants and its neighboring communities who also benefit from the reservoir.

    Beschreibung: Comparative primary production in Little Stream Farms, near Uyo was investigated in relation to physico-chemical parameters of the adjacent perennial stream and the fish ponds. Except for temperature, which showed the same values for both stations, physico-chemical variables generally showed significant difference (P〈O.05) between the pond water and the adjacent stream. Values of silicates, Turbidity (NTU), Secchi Disc Transparency and Total Suspended Solids (TSS) exhibited significantly variable trends (P〈O.05), especially in the stream water, in response to the commercial sand dredging activities upstream from the fann location. Lowest value of stream transparency (O.1M) recorded was during the peak of the sand dredging, whereas the stream water showed absolute transparency in the absence of the dredging. The water quality parameters also exhibited a general trend of significant seasonal variation (P〈O.05). Five phytoplankton families: Bacillariophyceae, Chlorophyceae, Cyanobacteria, Euglenophyceae and Dinophyceae occurred in the ponds, while three families, Bacillariophyceae, Chlorophyceae and Cyanobacteria occurred in the stream. Bacillariophyceae showed the highest relative abundance in both stations A and B.

    Beschreibung: The physico-chemical parameters of Lake Alau were monitored for four months to assess the water quality. Parameters such as temperature, transparency, conductivity, dissolved oxygen, biochemical oxygen demand, Ca, P, etc were studied in five stations (A, B, C, D and E). Water samples were collected monthly from 8:00 to l2:00noon, for four months (July - October 2008, wet season) and analysed. The physico-chemical parameters were within the ranges of unpolluted water bodies. Variation occurs in almost all the months of the study. Significant difference (P〈0.05) occurred in pH, transparency and Ca among the stations, and insignificant difference (P〉0.05) in temperature, conductivity, dissolved oxygen, biochemical oxygen demand, Mg and P. These variations may be due to effects of fertilizer application, herbicides and insecticides in irrigated farms around the Lake.

    Beschreibung: Study of some Physico-chemical parameters and fish species composition of Doma Darn was carried out between the month of August 2012. Fishing communities along the dam were selected at sampling stations and collection of fish species. The values of physico-parameters obtained for stations were in the range of 28.10-92 m for depth, 27.70-28.48~'for temperature, 7.03-7.64 for PH, 7.23-7.64mg/l for dissolved oxygen (DO), 30.08-31.75 ntu for turbidity, 94.64-105.17mg/l for alkalinity and 79.17-80.58mg/l for total hardness. The result indicated that there was significant difference (p〈0.5)for depth, temperature turbidity and alkalinity, while there was no significant difference (p〈0.05) for DO, pH and water hardness among the stations. The result of these parameters among the duration shows that there was significant different (p〈0.05) in all the parameters except pH. The study revealed that there were twenty-five (25) fish species belonging to 12 families in the dam. The family Cichlidae and Mochokidae and Bagridae which has three each, While the family, Polypteridae, Channidae, Centropomidae, flepsetidae and Protopteridae has the lowest number of one (1) each. The overall result revealed that the Phvsico-chemical parameters were mostly influenced by duration and not much by stations; and parametersoaram measured were within the recommended water quality requirement for growth and survival of aquatic organisms.

    Beschreibung: It was on July 1960 when 10 algal balls were acquired for exhibition at Suma Aquarium, Kobe. Permission to remove the specimens from the Lake Akan Reserve was given by the National Nature Reserve Committee. Algal balls, as a rule, lose their natural beauty when they are kept in an ordinary tank for a certain length of time. In an effort to retain the natural beauty it was decided to exhibit them in culture. This paper summarises the findings of this experiments with Cladophora sauteri. The author concludes that serious consideration has to be given as to the intensity of light, the sunlight, the water temperature and the nutrition for algal balls in culture in order to retain the natural beauty and shape.
