On the view of finding a new source of protein, Spathopsis rubens arcuata is one of fresh water bivalves inhabiting Nile River, Egypt. The quality of this clam as a human food was investigated. The herein results showed that S. rubens arcuata is a good source of protein, carbohydrate and with a negligible source of fat when compared with edible fishes. Myristic acid was the most abundant saturated fatty acid (SFA) while Myristoleic acid and Linoleic acid were the two most abundant unsaturated fatty acids. The nonessential amino acid Glutamine is the most dominant amino acid followed by Aspartic, Alanine and Leucine. Studying the safety of consuming the investigated clam was based on: 1) Studying the heavy metal content in relation to the environment and after a depuration period, 2) Studying the associated parasites. The results showed that the initial heavy metals (Cu, Cd and Pb) concentrations detected in soft tissues of the clam were high and exceeded the legal values. But the 8 days of depuration was an excellent strategy to reduce Cu, Cd and Pb to an acceptable level for human consumption. Seasonal study of the clam associated parasite showed that S. rubens arcuata harbors nonpathogenic ciliated protozoa Conchophthirus sp. and an annelid Batracobdelloides tricarinata as commensal organisms and a trematode Aspidogaster conchicola as a parasite. The present work concludes that S. rubens arcuata can be a good source of food for human on condition that arises in the market after a period of depuration reached to 8 days.

Distribution, abundance, length-weight relationships of the African giant prawn (Macrobrachium Vollenhovenii) in River Osun was studied. Four hundred and fifty (450) samples were collected at 45 per week for 10 weeks between April and June 2016, at two different landing sites (Atan and Asejire Lake). Morphometric analysis showed that the prawn exhibited positive allometric growth (L-W) with regression equation “b” values of 4.869, 6.627 and 6.205 in Atan, Asejire and pooled samples respectively. The correlation between L-W was high; r=0.580, 0.834 and 0.752 in Atan, Asejire and pooled samples respectively (p<0.05). The sex ratio of M. vollenhovenii examined showed female dominance over male with ratio of 1.57:1.00 in Atan, 1.78:1.00 in Asejire and 1.74:1.00 in pooled samples. The rostral spines on the dorsal side of M. vollenhovenii observed ranged between 11-15 while on the ventral side was between 2 and 7. The condition factors obtained in Atan, Asejire and pooled samples are 2.09, 1.58 and 1.667 respectively. The length-weight relationships of M. vollenhovenii show relationships between lengths and weights which get plumper as they grow longer. The correlation coefficient “r” indicated high correlation between length and weight. The samples were in good condition throughout the study period to depict that the environment as suitable for this prawn production.

Induced breeding in African catfish (C. gariepinus) became germane in addressing unreliable seed supply due to low fertilization and egg hatchability, improper selection and use of natural or synthetic hormones to induce ovulation and spawning. The proper use of hormones promote reproduction in fish which is controlled by several factors such as sex steroids in the regulation of reproductive processes which are controlled through the brain-pituitary gonadal axis. A review was conducted on recent comparative studies on the performance and survival rate of African catfish (C. gariepinus) larval produced under natural and synthetics hormones. More than 20 journal published papers on inducing ovulation and spawning in African catfish (C. gariepinus) either by using natural or synthetic hormones, mostly from West Africa were reviewed. Literatures suggested that, using synthetic or non- synthetic hormones ensure availability of matured quality eggs, and ensuring good and viable milt production for commercial fish farming. Among reviewed papers revealed that, higher fertilization, hatching and survival rate of African catfish larval were achieved at 0.4-0.5 ml/kg of Ovaprim compared to Ovatide, Ovulin and Pituitary Gland Extract. In ovarian lavage with combination of sperm and hormone method, the simplicity of induced spawning can be combined, with a less time dependent delivery of sperm than with conventio na l, in-vitro fertilization. Therefore, this review suggests that African catfish seeds production can be encouraged through the use of Ovaprim. However, Catfish Pituitary Gland Extract (CPE) which is more readily available at farm level can also be used in-vitro fertilization in case there will be any shortage of Ovaprim whose supply varies with changes in import duties. In addition, to optimize fertilization and larval rearing pituitary gland extract in combination with disinfectants such as FA and MG can be used.

An experiment was conducted to evaluate the effect of dietary addition by different levels of green tea Camellia sinensis on growth performance, body composition and blood biochemistry of Asian Sea bass, Lates Calcarifer. Therefore, Asian sea bass fingerlings with an initial body weight of 43.20 ± 0.11 grams were randomly assigned into 3 groups as triplicates has been used for the experimental period of 90 days. These fishes were tested with three experimental diets of similar protein content (514.8 ± 0.06 g/kg-1) and energy (48.4 ± 0.02 kcal/g). The first diet was treated as control against the other two without any inclusion of additives. The other two diets were mixed with green tea of 10 g/kg-1 and 20 g/kg-1 respectively. The results clearly shown significant (P<0.05) improvement of growth performance in all fishes fed with green tea as dietary additive when compared with control, whereas the maximum performance is attained from the first treatment with lower dose (10 g/kg-1) of additive. Overall results from the treatments revealed that the dietary inclusion in low levels of green tea as feed additives has relatively improved the growth performance, feed utilization and general health without any adverse effects on biochemical profile of Asian sea bass (Lates calcarifer).

The present study was aimed at the assessment of potential effect of selenium, supplemented in feed, on the hematological profile of tilapia (Oreochromis niloticus) while maintaining certain physicochemical parameters of water. Three doses differing merely in selenium contents viz. 2, 4, and 8 mg Se/kg of fish feed were formulated bearing in mind apiece dose as an independent treatment. Four cemented rectangular tanks (triplicated) were used after proper disinfection to ensure sustainable culture environment. 15 fish per tank were stocked after appropriate health examination weights ranging 10-25 g. Variations in different hematological parameters by counting of white blood cells, red blood cells, hemoglobin estimation, granulocytes (neutrophils, eosinophils, and basophils), agranulocytes (lymphocytes and monocytes) as well as weight and length gains were recorded and analyzed using one-way ANOVA. The results revealed that WBC’s counts were non-significantly (P=0.05) different among treatments 1, 2, 3 as well as in the selenium-deficient treatment. However, the counts of WBC’s, neutrophils, RBC’s and hemoglobin level was enhanced (P=0.05) in treatment-1 (2 mg Se/kg). On the contrary, hemoglobin level, neutrophil and RBC’s counts were significantly dropped (P=0.05) low in treatment-3 (8 mg Se/kg). The WBC’s counts were found lower in treatment-2 (4 mg Se/kg). Lymphocytes and monocytes were significantly higher in treatment-3 (8 mg Se/kg). This study has enlightened that the supplementation of selenium (2 mg/kg) in the feed of tilapia does not alter its inclusive hematological profile but promotes better physiological performance and productivity to enhance fish growth and paves the way towards increased supply of selenium-fortified fish meat.

Eleyele reservoir is a vital resource for fishery, domestic water supply and flood control. Unfortunately, the reservoir is fast being degraded due to various anthropogenic activities around its catchments. Hence, this study evaluates spatio-temporal variations in the physico-chemical parameters of the reservoir. Eleyele reservoir was stratified into five zones (S1-S5) based on hydrological features and three sampling points were randomly selected per zone. Water samples were collected bi-monthly from each station for 24 months covering wet (May-November) and dry (December-April) seasons. Water parameters were analysed for alkalinity (mg/L), phosphate (mg/L), Dissolved Oxygen (DO, mg/L), Biological Oxygen Demand (BOD, mg/L), Chemical Oxygen Demand (BOD, mg/L) and temperature (°C) following standard procedures. Highest and least alkalinity (103.63 ± 14.87; 96.25 ± 11.41) and phosphate (2.00 ± 0.69; 1.94 ± 0.66) were recorded in S2 and S4, respectively. Temperature and DO ranged from 26.53 ± 2.20 (S5) to 26.86 ± 2.45 (S1) and 4.24 ± 0.84 (S2) to 5.39 ± 0.82 (S5), respectively. Alkalinity were 99.72 ± 12.41 and 100.91 ± 16.14, phosphate (1.71 ± 0.55; 2.10 ± 0.61), temperature (28.20 ± 2.34; 25.53 ± 1.74) and DO (4.48 ± 0.98; 4.85 ± 0.97) in dry and wet seasons, respectively. The mean values obtained for Biological Oxygen Demand (4.29 ± 2.23 mgl-1), temperature (26.64 ± 2.36), conductivity (0.270 ± 0.21 μScm-1), alkalinity (100.42 ± 14.69), hardness (69.18 ± 30.94 mgl-1) and ions were within desirable limits for aquatic life. Crucial steps should be taken to reduce agricultural activities and anthropogenic discharges into the Reservoir.

This work aimed at ascertaining the nutritional suitability of some selected fish species in Ijede River, Nigeria. Evaluating the proximate composition, amino acids, mineral compositions and heavy metal accumulation of food fish is the most important aspect in fish nutrition. These were evaluated in Chelaeltiops bibie, Cithrarinus latus, Laeviscutella dekimpei, and Phago loricatus obtained from Ijede River, Lagos State, Nigeria, using standard laboratory procedures. All the amino acids analyzed were present in all the species examined with the highest value of total amino acids found in Laeviscutella dekimpei (283.1 mg/kg-1) except Phago loricatus that has the highest value of 70.00 ± 1.01. Minerals were also evaluated and the highest values were recorded in Phago loricatus with the exception of Calcium that has the highest value of 155.11 ± 1.22 mg/kg-1 in Laeviscutella dekimpei. It was observed that all the fish species analyzed bio-accumulate various metals and the concentrations of these metals exceeds their concentrations in the water sample analyzed. This data also revealed that the fish species sampled are of high nutritive value and are good sources of protein, amino acids and minerals. Amongst the sampled species, Phago loricatus appears to have the highest nutritive value but also the highest potential of heavy metal bioaccumulation.

Cyprinus carpio Linn is a kind of fresh water fish which is widely developed because the society likes it. Therefore, an appropriate plantation system is needed in order the available fish abounds. Plantation with sterile fish is one of the alternatives of providing the fish appropriately. The research was aimed to know the result of the forming of polyploidy on Cyprinus carpio Linn Punten race given heat shocking temperature after fertilization. The research design used is Completely Randomized Design with four times repeating for each experimental group. The data was analyzed using one-way ANOVA to know the effect of heat shocking temperature treatment toward the result of the formation of polyploidy. The finding of the research shows highly significant differences among the treatments toward the result of the polyploidy with 0,00 probabilities.
