    Beschreibung: Studies on the effects of crude oil and its fractions on the blood haemoglobin (HB) neutrophil (NP) concentration in the blood of Heterobranchus bidorsalis juveniles were carried out. Two study periods (toxicity and recovery) and four oil types (Bonny-light crude oil (BLCO), premium motor spirit (PMS), kerosene (DPK) and lubricating engine oil (lBO) at 1.00, 2.00, 4.00 and 8.00ml were used. There were significant differences (P〈0.05, p〈 0.01) on the HB and NP values in blood of fish samples. The elevated values of HB levels in fish exposed to 2.00,4.00 and 8.00m1 L-1 BLCC, 2.00ml L-1 PMS and DPK; and 4.00ml L -1 LBO over the levels in the control fish were in consonance with the results of other workers. Increases in NP values in fish exposed to the four oil types (BLCO, PMS, DKP and LBO) relative to the control could be part of the immunological attempts by the fish to mobilize the body's defence mechanisms. The relatively high percent mortality and low survival of H. bidorsalis juveniles exposed to 4.00 and 8.00mlL-1 concentration of the four oil types over the other concentration implied that these concentrations were probably lethal to fish existence.

    Beschreibung: The acquisition or loss of Clinostomum tilapiae parasites by Oreochromis niloticus was studied. Four groups of 25 healthy fishes were stocked in the upper part of serial experimental ponds, while another four groups of 25 infected fishes were also stocked at the rear part of the serial experimental ponds. All the groups were fed at 3% body weight with the same compounded fish feed. Acquisition or loss of parasites and growth was monitored for a period of six months. The mean relative growth rate was 11.04kg/month for the healthy fishes and 5.62g/month for the infected fishes. The mean specific growth rate was 38.75% and 31.25% for the healthy and infected groups respectively. However the results were not statistically significant (p 〉 0.05). The parasite did not multiply on the host body rather the infection rate reduced from 100% to between 44 and 78%, parasite burden was reduced from an average of 3 per fish to 2.25 while the healthy fish acquired the parasite and the average burden was 2.15. The mean values of the prevailing water quality parameters were within the optimum range acceptable in fish culture systems in the tropics.

    Beschreibung: The importance of information in every sector cannot be over-emphasized. The ability to identify and utilize our natural endowment depends on the availability of information resources within or at the right time. The low level of information provision in Nigeria is attributed to infrastructure as a result of inadequate funding of the sector. Research has shown that information has revolutionized the society, moving the world from the industrial age to the information age and completely changing the way the economy functions. Success goes with the best information. However, for now, if there must be increase in fish production and eco-tourism participation, employment opportunities, poverty reduction, food security and nature appreciation in terms of environment and living creatures, our fisheries scientists and policy makers will have to rely on sources of information using the advantage of libraries, and Information Communication Technology (lCT). This development in information resources affects many areas of Nigerian economy including the fisheries and eco-tourism sectors. The contribution of information resource in the development of the fisheries sub-sector can be viewed under those of fisheries information products like the Nigerian Fisheries and Aquatic Sciences. (NIFFIC) database, Proceedings of national conferences of Fisheries Society of Nigeria (FISON), annual and technical reports Fisheries Research Institutes in Nigeria. Also to be brought under perspective is the information products of eco-tourist institutions like the Nigerian National Parks.

    Beschreibung: A completely randomised design with three replicates was used for an experiment conducted to study the profitability of vitamin C inclusion into the ration formulation for Heterobranchus longifilis. Six different levels 0, 50, 100, 150, 200 or 250 mg of L-ascorbic acid (vitamin C) kg-1 diet was included in a 42.5% crude protein basal diet and fed to triplicate groups of twenty fingerlings. The groups fed diets with vitamin C had statistically significant (P〈0.05) higher final weight than the group fed the control diet without vitamin C at the end of twenty weeks study, Feed consumed was significantly (P〈0.05) lower in the group fed diet without vitamin C. There was a significant (P〈0.05) difference between the groups fed 0 and 50 mg vitamin C kg-1 diets, but no significant (P〉0.05) difference between the groups fed diets with 100, 150, 200 and 250 mg vitamin C kg-1 diet on this parameter. Mortality was significantly (P〈0.05) higher in the groups fed diet without vitamin C while there was no significant difference (P〉0.05) between the fish fed the diets with respective graded levels of vitamin C. The thiobarbituric acid reactive substance (TBARS) of the liver and whole body of fish was significantly (P〈0.05) higher in fish fed diet devoid of vitamin C. Cost per kilogram of fish base on feed input was significantly (P〈0.05) higher in the group fed diet without vitamin C than those enriched with vitamin C. However, within groups fed with vitamin C cost per kg of fish was significantly (P〈0.05) decreasing in the following order: diet 2〉 diet 6〉 diets 4, 5, and 3. There was no significant difference (P〉0.05) between fish fed diets 3, 4 and 5 with respect to cost per kilogram of fish. This study vividly showed that there is no alternative to the use of a complete diet with vitamin C in an intensive practical farming of H. longifilis geared towards optimum profit maximisation in terms of feed as one of the variable input.

    Beschreibung: The growth performance and nutrient utilization in Clarias gariepinus fingerlings fed cooked breadfruit (Artocarpus altilis) seed meal based diet as a replacement for maize, investigated for 8 weeks. Five (5) diets of breadfruit seed meal substituted for maize at different levels of inclusion (0%; 25%; 50%; 75% and 100%) were fed to the fingerlings at 5% body weight twice daily in hapa of 1m x 1m x 1m. The hapas wee submerged in a pond and each hapa stocked with 20 fingerlings of mean weight of 5.8~c0.00g. Evaluation of growth parameters nutrient utilization of the experimental diets showed that there was no significant difference (P〉0.05) in mean final weight (MFW); specific growth rate (SGR); feed conversion rate (FCR) protein efficiency ratio (PER) and apparent net protein utilization (ANPU) among the treatments. The results suggested a net advantage of replacing dietary maize with cooked breadfruit seed meal for Clarias gariepinus fingerlings at 50% and above levels of inclusion under the condition of the experiment.

    Beschreibung: In order to compare the effect of raw, cooked, toasted and extruded soybean meals on the growth and nutrient utilization of Heterobranchus longifilis fingerlings, 120 pure Heterobranchus longifilis fingerlings were purchased at the National Institute for Freshwater Fisheries Research (NIFFR) improved genetic fish hatchery and randomly allocated into four different treatments with two replicates each with 15 fingerlings in 8 aquaria tanks. Four different diets containing 40% crude protein each were compounded and fed to the fish at 5% body weight for 56 days. At the end of the feeding trials, growth performance and nutrient utilization were evaluated. The results revealed that fish fed toasted soybean-based diets had highest mean weight gain (MWG) of 16.39g, specific growth rate (SGR) of 2.03%/day, and food conversion ratio (FCR) of 2.18. The fingerlings fed the extruded soybean-based diet gave the least growth performance. It could be concluded in practice, that toasted soybean-based diet is optimal for growth of Heterobranchus longifilis fingerlings.

    Beschreibung: The physical and chemical characteristics of freshwater bodies Ikot Ebak and Abeneyentem streams in Essien Udim Local Government Area, Akwa Ibom State, Nigeria were studied from (July December 1996). The mean values obtained in the two water bodies were pH (6.8~c0.12, 6.8~c0.09, respectively). Conductivity (4.9~c2.26, 5.0~c2.09 iScm-1), total dissolved solid (16~c7.58, 37~c26.9 mg/l), TSS (46~c26.0, 53~c53.1)g/l), alkalinity (17.5~c7.27, 10.7~c8S MgCaCo3/1), DO (6.98~C1.46, 8.3~C29.0mg/1), BOD (2.65~c2.44, 3.15~c2.79mg/1), Salinity (0.41~c0.12, 0.31~c0.04%o') total hardness (0.64~c0.21, 0.84~c0.42mg/l, N03-N (0.31~cO.26, 0.35~c0.29mg/l), and PD4-P (0.022~c0.0199 0.023~c.022mg/1), respectively. There were significant difference in the means of the parameters in the two water bodies except TDS, Alkalinity and Hardness. The water bodies were found to be slightly acidic with low conductivity. The properties in the water bodies were in conformity with international standards for both drinking and aquatic life.
