| African catfish (<i>Clarias gariepinus</i>) larvae were fed on five preparations of decapsulated Great Salt Lake <i>Artemia</i> cysts: 1) dried (35°C, 6 h) and UV-irradiated cysts; 2) heated cysts (80°C, 10 min); 3) brine dehydrated and UV irradiated cysts; 4) micro-bound diet 1(with intact decapsulated cysts used in diet preparation 1); and 5) micro-bound diet 2 (with crushed and shifted decapsulated diet used in diet preparation 1). The larvae were fed from the first day after yolk-sac resorption (fourth day after hatching). After a 14-d rearing period, larvae fed on dried or heated decapsulated cysts or micro-bound diet 1. Feeding micro-bound diet 2 resulted in a significantly lower average gain in weight as compared to the other... |

| The aim of this work was to study the effects of sub-lethal exposure of lead acetate on the histopathology of the gills, liver, kidney and muscle and its accumulation in these organs of Clarias gariepinus. Results showed that lead accumulation in the tissues of C. gariepinus was dependent on the exposure period and lead concentration. Gills and liver were the predominant storage tissue and the order of accumulation in tissues was gill > liver > kidney > muscle. Some structural changes were observed in different organs, especially in the gills of the fishes exposed to lead acetate. Epithelial hypertrophy and epithelial lifting were apparent in the gills of exposed fishes. The degeneration of cytoplasm and secondary lamellae was also observed.... |

| ABSTRACT The purpose of the current study was to examine the effects of different feeds/nutrients and temperature on the gonadal development of Clarias gariepinus. The gonadosomatic index (GSI) and blood parameters including red blood cell count (RBCs), white blood cell count (WBCs), hemoglobin (Hgb) level, hematocrit (HCT), platelets (PLT) and mean corpuscular volume (MCV) were investigated. Four types of fish feed of 36% protein content [D1(fish meal), D2 (soybean meal), D3 (peameal) and D4 (commercial tilapia feed)] and 3 different levels of temperature (T1(24℃), T2(28℃) and T3(32℃) were tried in this study for a duration of 4 months. The mean values were as follows: female GSI (14.68 ± 4.86), male GSI (0.70 ± 0.32), RBCs x 106(2.45± 0.64), WBCs x... |

| This experiment was conducted to evaluate the effects of walnut (T. conophorum) leaf and onion (A. cepa) bulb on the gut morphometry of Clarias gariepinus towards elucidating its mechanism of growth promotion. Twenty Clarias gariepinus juveniles (7.39±0.29g/ fish) were allocated to nine treatments, with three replicates each. Nine experimental diets were formulated at 40% crude protein representing different level of walnut leaf and onion bulb (0.5%, 1.0%, 1.5% and 2.0%) respectively and the control diet was free from walnut leaf and onion bulb and were fed twice daily at 3 % body weight for 12 weeks. Growth indices like Mean Weight Gain (MWG), Specific Growth Rate (SGR), Feed Intake (FI) and Feed Conversion Ratio (FCR) were measured. Gut morphormetry such... |

| Two experiments were performed in order to determine the effect of supplementation of dry foods with live <i>Artemia</i> nauplii on the growth, survival, rate of cannibalism, and length-weight relationships of <i>Clarias gariepinus</i> larvae. It was found that <i>Artemia</i> -supplementation resulted in a significantly higher growth rate. The "condition", expressed as a length-weight relationship, was likewise altered after supplementation. The survival and rate of cannibalism were not influenced by supplementation. <i>Artemia</i> -supplementation of dry foods was compared with other approaches which are based on the concept of the 'adaptation weight'. |

| The effect of three dietary ascorbic acid (AA) concentrations, each applied via two feed types, on production characteristics and physiological condition of African catfish (<i>Clarius gariepinus</i>) larvae has been assessed in two 10-day culture trials. Three treatments received only <i>Artemia</i> nauplii enriched with an experimental emulsion containing 0, 10 or 20% ascorbyl palmitate (AP) and yielding 530, 1200 and 1600 µg AA g<sup>-1</sup> DW <i>Artemia</i> , respectively; the other three treatments were fed the same <i>Artemia</i> diets which were partially substituted by an artificial diet containing no vitamin C (ratio 20:80). No differences in survival could be observed: however, from... |
