Dr. Olusola A D E N I Y I Babalola
An experiment was conducted on the comparative growth performance of Clarias gariepinus larvae using Micro worms (Panagrellus redivivus) and Coppens crumbles respectively. Three thousand pieces of Clarias gariepinus larvae of 2 days old having mean weight of 4.5±0.05mg and length of 5.18±0.04mm was randomly distributed into two separate feeding trials A & B, and replicated thrice in each feeding trial. Clarias gariepinus larvae were stocked at the rate of 500 larvae per replicate in a slow flow-through system water vats measuring 0.9 x 0.45 x 0.45m 3. Larvae on feeding trial (A) were fed with 0.2mm Coppens crumbles while larvae on feeding trial (B) were fed with Micro worms. The larvae were fed thrice a day base on 5% body biomass for 28 days. There is significant difference (P≤ 0.05) in the feeding trials. Larvae on feeding trial (B) had higher weight gain, feed intake, specific growth rate, protein efficiency ratio, survival rate (%) and feed conversion ratio than Larvae on feeding trial A. Therefore, Panagrellus redivivus could be recommended for the feeding of Clarias gariepinus larvae due to their better growth performance.

Effects of Bee Pollen on Growth Performance, Intestinal Microbiota and Histomorphometry in African Catfish
Joanna Nowosad
This study aimed to determine the dietary effects of honeybee pollen (BP) on growth parameters, intestinal microbiota, hepatic histoarchitecture, and intestinal histomorphometry of African catfish Clarias gariepinus juveniles. The feeding experiment was carried out in a recirculating aquaculture system under controlled conditions for 21 days to achieve more than a 10-fold increase in weight in fish from the control group. Fish were fed well-balanced commercial feed without any supplements and served as a reference group (group C) and other diets enriched with varying BP levels as 1% (BP1), 2% (BP2), and 3% (BP3). Results showed a significant (p < 0.05) effect of the dietary BP not only on the growth parameters (such as final body weight: 5.0 g to 6.6–7.5 g, weight gain: 0.23 g/d to 0.31–0.35 g/d, body length: 84.7 mm to 93.8–95.9 mm, and specific growth rate: 11.7%/d to 13.1–13.7%/d, group C vs. experimental groups, respectively) but also on the development of beneficially import...
Growth, gut dimension, immune change and impact of Aeromonas hydrophila in Nile Tilapia (Oreochromis niloticus) fed Onion (Allium cepa. L) fortified diets
Abimbola O Adekanmbi
This study investigated effects of powdery Onions (Allium cepa) on the growth, gut area, innate immune reaction of Oreochromis niloticus and ability to resist Aeromonas hydrophila challenge. Six 35% crude protein diets were prepared adding fresh onions at 0.0% (OP0), 0.5% (OP1), 1.0% (OP2), 1.5% (OP3), 2.0% (OP4) and 2.5% (OP5) levels. Diets were allotted to triplicate groups of fish (1.79±0.14g) twice daily to apparent satiation for 12 weeks. Fish in each treatments were then challenged with Aeromonas hydrophila and followed for 2 weeks. After 84 days of feeding, growth was not significantly (P>0.05) varied by onion powder. Percentage survival rates was higher in fish fed onion supplements with a regression equation (Y = 75.655 – 10.423X – 1.399X2). Total heterotrophic count (THC) increased with higher inclusion of onion. . Red blood cells were higher in fish fed onion based diets in comparison to OP0 with values ranged from 1.68 x106/µL in OP0 to 2.83 x106/µL in OP1. Alkaline p...
Effect of low crude protein diets on the growth performance, survival and feed conversion ratio of the African Catfish, Clarias gariepinus (Burchell, 1822) larvae

HENRY OUMA
Improved culture of the African catfish (Clarias gariepinus) is important to addressing the increasing demand for fish especially in the developing countries. Hence, the present study evaluated the growth performance, survival and feed conversion ratio (FCR) of C. gariepinus larvae fed with locally formulated diet of low crude protein. The treatments consisted of crude protein (CP) contents of 35%, 30%, 25% and control (28 %). The fish larvae (average weight, 0.03±0.01 g and length, 20.0±0.01 mm) were stocked in glass aquaria at 7 fish/L, and reared at room temperature for 6 weeks. The fish larvae were sampled weekly for length-weight measurements. Prior to sampling, Water analysis was done for temperature, ammonia (NH3) and pH. Fish larvae fed on the test diets exhibited significantly higher length and weight, specific growth rate (SGR), and survival than those fed with control diet (p < 0.005). Specifically, C. gariepinus larvae fed 35% CP diet exhibited better growth performan...

The effect of zooplankton produced using rabbit manure and artemia on the survival and growth of larvae of Clarias gariepinus, Heterobranchus longifilis and heteroclarias

Ephrem TOSSAVI
Plurispecific fresh water zooplankton produced with rabbit manure, and dry artemia in powder (artemia Shell free) were used to evaluate survival and growth performances of larvae of Clarias gariepinus, Heterobranchus longifilis and heteroclarias witch initial weights are respectively 2.5 ± 0.0, 2 ± 0.14, 2.7 ± 0.1 mg for 12 days. Six experimental diets were tested in out of ponds by triplicate as follow: Czoo (Clarias gariepinus fed with fresh water zooplankton), Cart (Clarias gariepinus fed with artemia), Hzoo (Heterobranchus longifilis fed with fresh water zooplankton), Hart (Heterobranchus longifilis fed with artemia), HCzoo (heteroclarias fed with fresh water zooplankton) and HCArt (heteroclarias fed with artemia). At the end of rearing Czoo, Cart, Hzoo, Hart, HCzoo and HCart gave respectively survival rates of 74 and 73.5%, 63.5 and 60% and 70 and 62%. Final mean weights recorded were 15.54 ± 0.37, 13.3 ± 0.97, 34.13 ± 2.31, 36.46 ± 1.16, 18.14 ± 0.71 and 16.25 ± 0.52 mg for Cz...
Use of Probiotics as First Feed of Larval African Catfish Clarias gariepinus (Burchell 1822
Uchechukwu D ENYIDI
African catfish larvae do not have fully developed digestive system at onset of first exogenous feeding. Live feed like artemia have been used more than dry diets but is also costly. The gut microbiota may be influential in larval diet utilization. We therefore made three larval feed from two commercial probiotics and tested their growth and nutritional effects on first feeding hatchlings (larvae) of African catfish. The three diets were labeled as feed 1 (F1) made up of mixtures of mixtures of Lactobacillus acidophilus, Bacillus subtilis and Lactobacillus bugaricus, feed 2 (F2) was made up of 100% Saccharomyces cerevisiae and feed 3 (F3) was made up of 50% Lactobacillus mixtures and 50% Saccharomyces cerevisiae. The control diet F4 was decapsulated artemia. African catfish hatchlings were produced by artificial dry fertilization of brooders maintained in our lab. First feeding hatchlings 48 hours post fertilization (48 h pf) were stocked in well aerated 15l plastic aquariums at density of 100 larvae aquarium-1. There were three replicate aquariums per treatment feed. The photoperiod of the larval rearing system was 12 h D: 12 h L and the light intensity were maintained at 8 lux using black nylon coverings. The hatchlings were fed to satiation Original Research Article
