    Description: 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.

    Description: 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.

    Description: 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.

    Description: 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.

    Description: 200 fingerlings of African catfish (Clarias gariepinus) of average weight of 22.8~c0.04g were used to investigate the nutritive value of Pawpaw (Carica papaya) leaf-based diets. Five (5) isocaloric and iso-nitrogenous diets containing fishmeal protein at a rate of 0%, 25%, 50%, 75%, and 100% along with the pawpaw leaf were formulated. The diet without the pawpaw leaf meal serves as the control. The fish fingerlings were fed at 5% body weight per day for 56 days in plastic bowls. It was observed at the end of the experiment that pawpaw leaf meal was suitable as a protein supplement when incorporated at 50% replacement. The body weight gain, specific growth rate (SGR) and food conversion ratio (FCR) values of 18.68g, 1.07%/ day and 4.72 respectively were highest in diet with 50% replacement closely followed by diet with 25% replacement. Based on the results, it could be recommended that in practice 50% replacement of pawpaw leaf meal with fish meal is optimal in practical diet of African catfish (Clarias gariepinus) fingerlings. Nevertheless, complete replacement of pawpaw leaf meal decreases growth rate and should not be used in Clarias gariepinus fingerlings.

    Description: Lagos state has a major sea port for landing of frozen fish from Mauritania, Senegal, the Scottish waters and other European countries. In the last three years, the dense population of the state has encouraged all kinds of trade to thrive. Fish as a major food in many Nigerian diets has been known to complement the high carbohydrate intake of majority of the Nigerian populace because of the unaffordable prices of beef in the market. The market for frozen fish is rich in Lagos. It has provided many women fishmongers a livelihood for over a decade. They have been able to sustain their families and improve their social status over the years. This study reports the modus operandi of the trade. The study covered a period of three months. Fish sales were monitored in Epe, Oyingbo, Ijora and Alaba markets. The cooperation of the heads of markets (Iya Olojas) were requested at every market. It was ensured that observations and the interviews/questionnaires do not interfere with the women's activities. Specific areas focused upon in the study included countries of fish imports, most acceptable species, packaging, purchase price, sales price and profit margins. Other important factors in the fish market that were studied included entrance into the fish marketing business, sources of finance and problems. The study also made suggestions on how to improve upon the fish marketing business of women in Lagos State.

    Description: Ten specimens of African cuttlefish, Sepia bertheloti, from the coastal waters off Qua Iboe River, Southeast Nigeria, were analyzed for the relationship between the concentration of the elements and the size of the species. Energy Dispersive X-ray fluorescence technique was employed to determine the elemental composition of the species. Eleven elements were identified in the body of cuttlefish. These were Chlorine, Strontium, Potassium, Calcium, Bromine, Iron, Copper, Zinc, Manganese, Nickel and Selenium of these elements, the concentration of calcium, potassium. Copper and strontium had a positive correlation with the weight, while the concentrations of manganese, nickel, chlorine, iron were negatively correlated with their weights. However, only manganese had a significantly negative correlation (p〈0. 05). Bromine and zinc had no correlation with the weights of the species. There also existed a significant positive correlation between Ca and K, Se and Ni, Cu, Br and Zn and St and K. We conclude that African cuttlefish, irrespective of size is a rich source of nutritional elements and is especially recommended for pregnant women and for all age groups.

    Description: Sixteen (16) weeks feeding trial in a randomized design with three replicates was conducted to study the response of 180 Oreochromis niloticus fingerlings to baobab pulp as a source of vitamin C. They were fed a basal diet without supplemental vitamin C in the first 2 weeks of conditioning to deplete some stored acrobate. Diets supplemented with 1008 mgascorbyl-2-monophosphate Mg2+ (AMP) kg-1 diet (diet 1); 84g baobab pulp kg-1 (diet 2) and 168g baobab pulp kg"1 diet (diet 3) were evaluated. There was no significant difference (P〉0.05) in terms of weight gain, feed efficiency ratio, protein efficiency ratio, specific growth rate and survival between the groups fed diets 1 and 3. There was a significant difference between the groups fed diet 2 and either of the other diets. Total ascorbate concentration of the liver was significantly (P〈0.05) higher in the groups fed diet 3. The crude protein content of the final fish was significantly (P〈0. 05) higher in the groups fed diet supplemented with AMP. Interestingly none of the groups exhibited the characteristic symptoms of vitamin C deficiency. The results of this experiment suggest that Oreochromis niloticus was able to obtain vitamin C from the baobab pulp and tend to recommend baobab pulp at a level not less than 168g kg-1 diet in the nutrition of Oreochromis niloticus based on the condition of this study.

    Description: Four different shrimp species; Penaeus monodon, Macrobrachiwn vollenhovenii, Macrobrachium felicinllm, Parapenaeopsis atlantica were collected from Lagos and Ondo states coastal waters and examined. The length (em), weight (g), head weight (g), tail weight (g), number of upper and lower rostrum teeth were determined. The species varied differently in weight ranging from 100.70g, 48.30g, 12.l0g and 9.20g for each species respectively. Length of 27.60cm, 18.l0cm, 15.70 and 10.40cm were recorded, head weight of 33.90g, 24.90g, 4.40g, 7.40g. Tail weight; 67.30g, 24.l0g, 7.70g and 3.20g were recorded. While the number of upper and lower rostrum teeth in P. monodon, M. vollenhovenni, P. atlantica, and M. felicinum were; 7-10/1-3, 11-14/3-5, 5-1110, 12-16/3-5 respectively. Penaeus monodon had the highest weight (l00.70g) but had rostrum teeth of 8/3. The result obtained for the species in homogenous subsets revealed that in weight (g), M. felicinum and P. atlantica falls into the same subset, while M. vollenhovenii and P. monodon fall into different subsets. In the length (em), all four species fall into different subsets. In the head weight (g), P. atlantica and M. felicinum fall into the same subset while M. vollenhovenii and P. monodon fall into different subsets. In tail weight, it was also applicable. In number of teeth on the upper rostrum all four species fall into different subsets and in number of down rostrum P. atlantica and P. monodon fall into different subset while M. vollenhovenii and M. felicinum fall into the same subset.

    Description: The effect of selenium supplementation into diets of Heterobranchus longifilis fingerlings was investigated using a completely randomized design with triplicates in a mini-flow through experimental system. 245 fingerlings (mean wt., 1.5~c0.23g) were stocked and fed either normal (Basal) diet (Control group) or diets supplemented with 0.16, 0.24, 0.32 or 0.64 mg sodium selenite Kg-I Selenium addition to the diets and fed to the fish caused a significant increase (P〈0.05) in weight gain and fingerlings growth rate was accelerated by 18-22% compared to 17-18% in the control group. There were significant differences (P〈0.05) in survival rate between treatments, indicating that diets are likely to be responsible for increased survival rate, observed in fish fed diets supplemented with 0.24 and 0.32 mg Na2 Se03 5H2O kg-1 diet. Results indicated that a diet supplemented with, 0.24 and 0.32 mg of sodium selenite Kg-1 diet is important for growth and survival of H. longifilis fingerlings.
