Efficiency Ratio

Growth performance, feed utilization, survival and body indices of African catfish Clarias gariepinus juveniles fed diets containing maggot meal as replacement of fish meal was evaluated for 42 days. Sixty fingerlings of Clarias gariepinus, average weight of 10 g were randomly distributed into six circular tanks at the rate of 10 fish per tank. There were two treatments, DT1(maggot meal-based diet) and DT2 (fish meal-based diet). The fish were fed twice daily. Water quality parameters were monitored on a weekly basis throughout the experimental period. Growth, nutrient utilization and body indices parameters were evaluated at the end of the experiment. Crude protein, crude lipid and ash were higher in the fish meal-based diet (34.65%, 7.33% and 18.03% in DT2 as against 28.70%, 7.20% and 11.0.1% in DT1 respectively), while crude fibre was higher in maggot meal-based diet. The selected water quality parameters: temperature, dissolved oxygen, ammonia and pH were slightly lower in maggot meal based treatment, but none of them was differently significant. Mean weight gain, specific growth rate, protein intake, protein efficiency ratio, lipid intake and lipid efficiency ratio (17.25±0.70 g, 2.39±0.06 %/day, 95.50±1.27 g, 1.81±0.06, 23.96±0.32 g and 7.20±0.24 respectively) were all significantly higher in DT2. The feed conversion ratio was higher significantly in DT1. Survival, hepatosomatic index and condition factor were similar between the two treatments. Though the aforementioned body indices indicated that the total replacement of fish meal with maggot meal is not harmful to the fish, a partial replacement may be better for optimum output

Comparative study on African catfish hypophysation indices using ovaprim and chicken pituitary gland extract (CPGE) was carried out. Sixteen (16) African catfish brood stocks between 1100 and 2300 g in ratio 2:1 and four (4) numbers of layer birds (Gallus gallus domesticus) between 1200 and 2200 g in ratio 1:3 were used respectively. The experiment was batched into “A” and “B”. Batch ‘A’ was placed on ovaprim while batch ‘B’ was placed on CPGE. An indoor hatchery vat, measuring 0.6096 m x 1.8288 m x 0.3048 m each was used for the incubation. Digital measuring kits were used to monitor water quality parameters and measurement of the brood stocks weights independently. Brood stocks on ovaprim and CPGE treatments had the following mean hypophysation indices in these order: fecundity (11100±7690 and 17760±13863), latency period (9.53±0.54 and 9.77±0.49), fertilization percentage (94.03±5.90% and 90.6±10.11%), hatchability percentage (75.6±0.81% and79.35±10.27%), number of eggs produced (5889±657.37 and 9403.33±589.80), total number of larvae hatched (4717.33±1111.0 and 7111.33±506.64), SGR (0.67±0.31 and 1.1±0.31), and survival rate (64.81±0.71 and66.24±2.19) respectively. There was no significant difference (p = 0.05) in the mean values of fecundity, latency period, fertilization and hatchability percentages in both treatments but there was significant difference (p ≤ 0.05) in number of eggs produced and total number of larvae hatched in both treatments. The water quality parameters were within the range for induced breeding techniques and there was no significant difference (p= 0.05) in both experiments. Both ovaprim and CPGE had excellent results from the induced breeding of Clarias gariepinus and yielded good results. Therefore, CPGE could be recommended from the view point of excellent results and its availability from chicken slaughter houses as against ovaprim which are imported.

This study aims to determine the effect of artificial feed by adding cassava leaf flour (Manihot utillisima) to the water quality of the African catfish nursery pond (Clarias gariepinus). This study used the T test (one sample T test) to compare the treatment with artificial feed and commercial feed consisting of 3 replications. The feeding dose was 3% of the weight of the fish for 30 days of maintenance with the frequency of feeding twice a day. Parameters observed were NH3, NO2, NO3, pH, temperature, DO and survival of African catfish. The results showed that the provision of artificial feed in the African catfish nursery did not have a significant effect (P> 0.05) on the observed water quality parameters. The quality of water obtained during maintenance by providing commercial and artificial feed is still supporting the survival of African catfish.

Fish Feeds

There is paucity of information regarding efficiency and suitability of most imported floating feeds used for growing catfish in Nigeria. This study therefore determined proximate compositions of three commercial floating fish feeds (Vital Feed, Top Feed and Allier Aqua Feed) and their effects on growth parameters when fed to juvenile African catfish (Clarias gariepinus). 65 litre capacity rectangular plastic tanks were stocked with healthy juveniles catfish of similar average weight were fed with these feeds for a period of 56 days (8weeks at the rate of 20 fish per tank. A triplicate trial was maintained for each feed, totalling nine tanks in all and 60 fish per feed. The tanks were labelled based on the type of feed. The rearing water quality parameters were monitored throughout the experiment. The results indicated that catfish fed with Top Feed had significantly (p80%) were observed in all groups while water quality parameters were not affected due to the feed offered. The results of the proximate composition attested to the fact that feed with high protein and lipid contents results in better fish growth i.e. Top feeds with high protein (45.16±2.73) and Allier Aqua with high (13.00±2.11) content. Variations in growth parameters and estimated cost of feeding observed in the present study imply that catfish that catfish farmers should exercise great caution in selecting commercial floating feeds for their fish since these feeds produce different growth effects on fish.

The Cost

The study was designed to investigate the rate of larval (maggot) production from different culture enclosures, as well as to compare the cost effectiveness and utilization of the maggot in the diet of African mud catfish, Clarias gariepinus. Musca domestica larvae were cultured from poultry dung for five week, where upon they were utilized as a replacement for fish meal in the diet of fingerlings of African mud catfish. The maggots were cultured in four different enclosures: aluminium mobile maggotry, aluminium, plastic and wooden boxes. The harvested maggots were processed by oven drying and powdered as maggot meal. The maggot meal was used to substitute fish meal in eight diets with different inclusion levels of 0% (control), 20%, 30%, 40%, 50%, 60%, 70% and 80%. The formulated diets were fed to C. gariepinus fingerlings in triplicates for 10 weeks. The growth, nutrient utilization and survival of fish were monitored during the experimental period. The cost effectiveness of different culture enclosure was studied. Results indicate that aluminium box was the best option, giving the highest weight of maggot production, and was the most cost effective of all the culture enclosures studied. Significant differences (p < 0.05) were recorded in weight gain of fish between the control and the maggot meal-based diets, while the highest weight gain was observed in fish fed 70% maggot meal-based diet. Specific and relative growth rates were found to be high in fish fed 60% maggot meal diet, while they were lowest in fish fed 20% maggot meal diet and the control diet. The best protein intake was recorded in fish fed the 70% maggot meal-based diet and lowest in fish fed the control diet. Survival of fish was generally high (78.3%-93.30%) and was significantly (p < 0.05) different between the fish fed as the control and the maggot meal-based diets. The study confirms that maggots of Musca domestica are suitable as partial replacement of fishmeal at 60-70% inclusion level for optimal growth performance and nutrient utilization in Clarias gariepinus fingerlings.

Effect Of Feeding

 No or little information on the use fresh (wet) housefly maggots (Musca domestica) in African catfish (Clarias gariepinus) fry feeding. Therefore, this study was conducted to investigate the effect of feeding on fresh (wet) housefly maggots with or without artificial diet on water quality, growth performance, survival percentage and feed utilization of African catfish fry under laboratory conditions. Housefly maggots produced from a mixture of poultry droppings and foods wastes, it was used to replace artificial feed at 0, 50 and 100% levels. Catfish were fed artificial diet alone (Feed 1), fresh (wet) housefly maggots alone (Feed 2), and 50% fresh housefly maggots with 50% artificial diet (Feed 3) were prepared and tested on triplicate groups of African catfish fry (initial weight of 0.25±0.02 g) for 60 days. Results showed that final weight (g/fish) was significantly highest (P£0.05) in fish fed feed 3 (6.03±0.08), followed by fish fed feed 2 (4.62±0.27), followed by fish fed feed 1 (3.15±0.68). Specific growth rate (%/day) was also significantly highest in fish fed feed 3 (5.31±0.10), followed by fish fed feed 2 (4.86±0.03), followed by fish fed feed 1 (4.18±0.24). The same trend was observed with total weight gain, percentage weight gain, daily growth rate and relative growth rate. Feed intake and protein intake were significantly highest (P£0.05) in fish fed feed 3 and fish fed feed 2, followed by fish fed feed 1. While, feed conversion ratio (FCR) and protein efficiency ratio were not significantly (P>0.05), but the improvement in FCR recorded in catfish fry fed feed 3 and feed 2 under the experimental conditions. Survival percentage was within the range 55–75%, with insignificant differences (P>0.05) among treatments. The water quality parameters such as temperature, pH, dissolved oxygen, total ammonia, nitrite and nitrate were not significantly (P>0.05) among the treatments and were tolerable for fish culture. Accordingly, use of the 50% fresh (wet) housefly maggots with 50% artificial diet in African catfish fry feeding had positive effect on growth performance and reduce of the feed cost.

Growth performance and survival of Tor putitora fry under different stocking densities were evaluated fry rearing system. The experimental period was 10 weeks from 31 December to 10 March 2019. The experiment was carried out in nine earthen ponds of 0.04 ha each under three treatments with three replications.  Thirty days old fry were stocked at the rate of 1.0X105/ha was designated as treatment- 1 (T1), 1.5X105/ha` as treatment- 2 (T2) and 2.0X105/ha as treatment- 3 (T3), respectively. Fry were fed with commercially available nursery feed containing 32% crude protein. It was observed that, lower stocking density showed highest daily weight gain in T1 (growth 0.066 ± 0.006 g/day) compared with higher stocking density in T2 (growth 0.044 ± 0.004 g/day) and T3 (growth 0.024 ± 0.003 g/day), respectively. It is also noticed that, the lower stocking showed the highest survival rate (79.66 ± 4.34 %) than the other two treatments (66.97±3.67 and 54.67± 3.12 %). The values of different water quality parameters were within the optimum ranges for the rearing of carp fry. Water quality parameters did not show significant variations in the experimental ponds under different stocking densities. Among these three stocking densities lower stocking density (T1) showed the best result compare with the other two higher stocking densities.

This trial aimed to evaluate effects of stocking densities of 1-5 fish/m2 on growth performance, survival rate and economic efficiency of Asian seabass (Lates calcarifer) in earthen ponds. Fish with an initial length of 90.7 ± 0.1 mm and weight of 20.8 ± 0.1 g/fish and ponds with 600 m2 each and 1.5 m depth were used for this study. Experiment was designed with three treatments, including different stocking densities of 1, 3 and 5 fish/m2. The fish was fed with pellete feed containing 43 - 44% crude protein. Water quality parameters including temperature, dissolved oxygen, pH, salinity, transparency and ammonia concentration were measured once a week. Fish were sampled every 30-day intervals for length and weight measurement then for their growth estimation. Costs were recorded for economic efficiency estimation. Results showed that the water quality parameters were in suitable ranges for growth and development of Asian seabass. The final average length and weight of density 1 fish/m2 was significantly higher than those at 3 and 5 fish/m2 (P < 0.05). However, there was no significant difference on the fish growth in terms of daily length and weight gain, as well as survival rate and feed conversion ratio between different stocking densities. Asian seabass culture at 3 and 5 fish/m2 resulted in a higher profit compared to at 1 fish/m2. The highest economic efficiency in terms of area pond was showed at 5 fish/m2 treatment.
