    Description: Oreochromis niloticus was reared in 54 litre glass tanks being fed with 35% crude protein diets for 56 days. A basal diet consisting intact protein from groundnut cake and guinea com (4.56g lysine/100g protein) ,four graded levels of crystalline lysine was added to formulate diets consisting 6.87, 7.30, 7.41, 7.51 g lysine /100g protein and a reference diet of intact protein from groundnut cake, guinea com and fish meal having 5.37g lysine/100g protein was fed to six treatments in triplicate groups. The growth parameters shows there was no significant difference in the mean weight gain, specific growth rate, food conversion efficiency and protein efficiency ratio of fish fed varying levels of lysine. A maxima was obtained from the quadratic equation of food efficiency ratio against graded levels of lysine at 7.3g/100g protein which is the requirement. Carcass ash was higher with the initial fish while crude protein was highest with the the fish fed 7.3g lysine/l00g protein

    Description: The contribution of tilapia aquaculture in Nigeria to world output is negligible due to stunting, poor market value among others. This paper evaluates the aquacultural credentials of tilapia, some genetic improvement technology in cultured tilapia, namely, ploidy, hormonal sex reversal. transgenic, hybridization, and the necessity of Genetic Improvement in accelerating tilapia production in Nigeria. Investigation reveals the presence of O. niloticus with the highest growth perfermancc index (~h1=3.11) for Lake Kanji which indicates high growth potential in suitable culture environment and could serve as a good starting point for genetic development. The presence of ”wesafu”, an ecotype cichlid, endemic to Epe lagoon, Lagos, which grows to 1500g in the wild, appears to be an excellent candidate for genetic improvement of a commercial strain for the growing aquaculture industry. Tilapia Genetic improvement in Nigeria is faced with a number of setbacks. This includes short- term, scattered and disjointed funding, inadequate genetic research facilities, ecological risk, inadequate skilled manpower and poor documentation of tilapia genetic resources among others. Considering the growing importance of tilapia culture, the need to document, conserve, evaluate and utilize tilapia genetic resources is highlighted to enhance the success of food security in Nigeria.

    Description: Hunger and malnutrition have remained amongst the most devastating problems facing the majority of Nigerian poor. These challenges and other social and economic objectives are the main forces driving aquaculture development to augment for food deficient, in particular fish, which is the cheapest source of protein. However looking at the aquaculture potential and the demand for fish, more needs to be done in aquaculture sub-sector. Unfortunately, despite the increase awareness, many people still remain skeptical about returns in aquaculture investment. This backdrop prompted the study, which empirically analyzed the situation based on two (2) semi-concrete ponds at NIFFR. The results which were extrapolated for five years shows a cost benefit ratio of 1.8, which indicated worthy investment. The results would essentially serve as guide to practitioners and intended fish farmers

    Description: Four treatments (in duplicate) were used to detennine the optimum combination ratio in the chicken-fish integrated system in 4 m2 concrete ponds. Treatment I (TI) consisted of a concrete pond integrated with one point-of-lay chicken while treatment 2 (T2) had two point-of-Iay chickens integrated over a concrete pond. Treatment 3 (T3), consisted of three point-of-lay chickens integrated over a pond and treatment 4 (T4) was the control and involved no integration. Each concrete pond was stocked with a poly-culture of Oreochromis niloticus and Clarias gariepinus in a ratio of 3:1. Compounded fish feed was used to feed the fish in T4 twice daily at 5% of their body weight while fish in TI. T2 and T3 fed on wet chicken manure and spilled chicken feed that fell directly into the ponds. The daily manure loading rate ranged from 55.80g in TIR2 (treatment l replicate 2) to 117.37 g in T3RI while spilled feed loading rate ranged from 2.52 in T2R2 to 9.27g in T3R2. The total number of eggs laid was 871 in 84 days. For C. gariepinus, fish in T4RI had the highest mean weight gain of all the treatments and TIRI, the lowest. T3R2 had the highest mean weight gain of all the integrated treatments. For O. niloticus fingerlings, fish in T4 which were fed compounded feed had the highest mean daily weight gain and while those in T1 had the lowest. T4RI fish had the highest mean weight gain while TIR2 fish had the lowest. Fish in T3 had the highest mean weight gain of all the integrated treatments followed by fish in T2. However, physico-chemical parameters were more adverse and survival was lower in T3 than in T2 and so a combination ratio of 20 fingerlings in a 4 m2 concrete tank integrated with two laying chickens (mean weight 1.93 kg) is recommended. This translates to 50 laying chickens/100 m2 concrete pond stocked with 500 fingerlings.

    Description: This study was carried out to assess microbial quality of smoked catfish (Clarias gariepinus) treated with citric acid during 5-week storage at room temperature. Raw catfish were subjected to the following treatments for 5 minutes prior to smoking: 1-5% citric acid. The non-treated catfish served as control. The control samples showed diverse and high microbial load. All treated smoked sample were negative for E. coli and Streptococcus sp. and low in their TVC, coliform, staphylococcus and fungi and maintained these low count till the end of the 5th week storage. Treatment with 5% gave the best result but I and 2% citric acid are prefered by the consumers. Treatment with 2% was recommended as an acceptable concentration in preserving smoked catfish due to its effectiveness and acceptance by the consumers.

    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.

    Description: Interspecific and intergeneric hybridization studies were carried out in H. longifilis, C. gariepinus and C. anguillaris under controlled hatchery conditions to estimate their aquaculture potential in terms of fertilizability, hatchability and survival. Fertilization rate in all the nine genetic crosses ranges from 60-87.5%, the fertilization rates of the parentals being significantly higher(P〈0.05) with highest value of 87.5% obtained in C. gariepinus. The intergeneric hybrids had the lowest rate of fertilization. Hatchability ranges between 75- 88.1 %, with the parental C. anguillaris being slightly significantly higher than the other genetic combinations. C. anguillaris x H. longifilis I had the lowest hatchability and there was no significant difference (P〈0.05) in percent hatching among the the interspecific hybrids. The survival of all the nine genetic crosses from hatching up to the end of the two weeks indoor rearing period ranges between 78-89%, which wasn't significantly different among the interspecific and intergeneric hybrids. C. anguillaris and C. gariepinus had the highest percent survival which was significantly different from all the other mating combinations. The intergeneric hybrid larval had significantly greater (P〈0.05) length in comparison to the interspecific hybrids. H. longifilis and the hybrids produced from its eggs had greater body weight than that of C. gariepinus and C. anguillaris
