    Notes: This study was undertaken to determine the replacement value of Cassia fistula seed meal (CFM) for soybean meal (SBM) in practical diets of Oreochromis niloticus fingerlings. Five practical diets (350 g kg−1 crude protein) containing 0 g kg−1 (control), 170 g kg−1 (diet II), 340 g kg−1 (diet III), 509 g kg−1 (diet IV) and 670 g kg−1 (diet V) substitution levels of CFM for SBM were formulated and fed to triplicate groups of O. niloticus fingerlings (mean initial weight of 10.22 ± 0.03 g) for 70 days. Fish mortality increased linearly with increase in inclusion levels of CFM in the diet. Growth and diet utilization efficiency were depressed in fish fed diets containing CFM at varying inclusion levels. Feed conversion ratio, specific growth rate and protein efficiency ratio of O. niloticus fed on diet containing 170 g kg−1 substitution level of CFM were similar (P 〉 0.05) to the control diet. Digestibility of the different diets decreased with increase in inclusion levels of CFM. Fish fed diet containing 670 g kg−1 CFM had significantly lower carcass protein. However, no significant differences were observed in carcass protein and lipid contents between fish fed the control diets and diet containing 170 g kg−1 CFM. The most efficient diet in terms of cost per unit weight gain of fish was obtained in 170 g kg−1 CFM dietary substitution.

    Utilization of cocoa-pod husk in low-cost diets by the clariid catfish, Clarias isheriensis Sydenham (1992)

    Notes: Abstract. Clarias isheriensis Sydenham fingerlings (60·42 ± 1·13g) were fed for 180 days with pelleted diets in which maize was progressively replaced with graded levels (0, 15,30,45%) of cocoa-pod husk meal (CPHM). There was a decline in growth rate with increase in dietary CPHM level, though this was not significantly different (P 〈 0·05). Differences in feed conversion, nutrient digestibility and carcass characteristics among different dietary treatments were also not significant (P 〉 0·05). Fish mortality was low (〈 2%) in all dietary treatments tested. Lack of significant difference in growth performance and nutrient utilization indicated that CPHM could be incorporated into low-cost diets for C. isheriensis up to the 30% level.In a second experiment, three feeding regimes of 15% CPHM diet were tested with C. isheriensis fingerlings (60·81 ± 1·87g) over 180 days and results showed no significant (P 〉 0·05) differences among the feeding regimes tested, with regards to growth, feed conversion and fish yield. This suggests that the growth of C. isheriensis from fingerling to adult size (≥ 200g) can be satisfied in one single feeding equivalent to 3% body weight per day.

    Description: The acute toxicity of promethazine hydrochloride (phenergan) to Clarias gariepinus fingerlings was conducted using static bioassay under laboratory conditions. The 96h LC50 was determined as 172.5 mg/1. Mean mortality was 5, 10, 20, 50, 100% in the concentration of 69, 103.5, 138.0, 172.5 and 207 mg/1 respectively, while there was no mortality in the control treatment. There were significant differences (P〈0.05) on the effect of concentration, the higher the mortality of C. gariepinus fingerlings while toxicity of phenergan increased with duration of exposure. C. gariepinus showed increased hyperactivities, cell deformation, lesions and necrosis during the period of exposure. The physicochemical parameters also showed a slight increase as the concentration increased.

    Description: Nigeria has a coastline of 853km and over 14 million hectares of inland waters and thus owns significant fisheries. The contribution of fisheries to the Nigerian economy is significant in terms of supply of high quality dietary protein, income generation, creation of employment and enhanced inflow of foreign exchange earnings through shrimp export. However, due over-exploitation of the natural resources, by-catch and discard problem, inadequate infrastructure and social amenities development, inadequate supply of fish feed, fish seeds and slow adoption of new technology and management strategies etc. The domestic fish production (0.55 million tons) has fallen short of the demand (1.5million metric tons). Aquaculture development is the solution to the unpredictable production through capture or artisanal/industrial fisheries.

    Description: Pawpaw (Carica papaya) seed meal (PSM) was added to a basal diet (350g crude protein and 18.5MJ gross energy lkg diet) at 0, 0.5, 1.0, 1.5 or 2.0 g/kg diets and fed to mixed-sex Oreochromis niloticus for 60 days to evaluate the effects on growth, feed conversion ratio, reproduction traits, and histology of gonads. There were no variations (P〉0.05) in growth parameters and feed conversion ratio. Indices of reproduction traits decreased with increasing dietary PSM levels. Fish fed with the basal diet had higher and better indices of reproduction traits (P〈0.05) than the fish fed with PSM diets. Fish fed O.0g PSMlkg diet showed normal testicular and ovarian tissues, and no lesions were observed. Fish fed O.5g PSMlkg diet showed slight increase in interstitial cells in testes. Fish fed 1.0g PSMlkg diet showed swollen spermatids nuclei, increased interstitial cells and focal necrosis in testes; and hydropic degeneration, ruptured follicles, granulomatous inflammation in the insterstitium and necrosis in ovaries. Fish fed 1.5g PSMlkg diet exhibited atrophy of seminiferous tubules in testes. Fish fed 2.0g PSMlkg diet, there was disintegration of spermatids and necrosis in testes and severe atretic follicles in ovaries. Reproduction traits and histological observations of gonads in O. niloticus fed high dietary PSM levels revealed that pawpaw seeds may be effective as a reproduction inhibitor in O. niloticus.

    Description: The effects of 96 h sub-lethal concentrations of African locust bean effluent on Oreochromis niloticus were studied using plastic buckets. Packed cell volume (PCY) and histological study of gills and liver were the tissue chemistry parameters investigated. The control buckets contained no effluent. Results revealed increase in ESR (Erythrocyte Sedimentation Rate) decrease in haemoglobin, red blood cell and PCY Yalue of the fish exposed to all sub-lethal concentrations. Damage to liver and gills were noticed in some of the sub-lethal concentrations of all the effluent. Normal situation was observed in all the examined tissues of fish from the control buckets. The African locust bean effluent is toxic on O. niloticus and the lethal concentrations of African locust bean effluent deducted from the 96 hours acute toxicity effect ranged from 3ml.

    Description: The effect of substituting soybean meal with raw sunflower and sesame seed meal was evaluated using haematological indices of Clarias gariepinus fed the diets containing sunflower and sesame seed meal. Seven isonitrogeneous and isocaloric diets containing sunflower and sesame seed meal replacing soybean meal at a rate of 15, 30 and 45% were prepared. A diet without replacement of soybean meal served as control. The result of fish fed test diets showed significant (P〈0.05) difference over the fish fed control diet with respect to PCV and mean corpuscular volume (MCV). Fish fed control diet had the lowest Hb, PCV, WBC, RBC, MCV, MCHC, ESr. There was no significant difference (P〉0.05) in the fish fed control diet and test diets with respect to MCH, MCHC, ESr, Neutrophil, Monocytes, Eusinophils and Lymphocytes. Hence it can be concluded that the haemotological parameter of Clarias gariepinus is not significantly (P〉0.05) changed with increase dietary inclusion of raw sunflower and sesame seed meal.
