THE EFFECT OF MAGGOT AND SNAIL MEALS BASED DIETS ON LARVAL PERFORMANCE OF CLARIAS GARIEPINUS (BURCHELL, 1822)
Abstract
The transition from endogenous to exogenous feeding is a critical event in the life of a fish. Great losses are sustained in the hatchery, as fry weans over from yolk absorption to exogenous feeding. Till today in Cameroon, exogenous feed for larval rearing to fingerlings is imported and very costly. This study aimed to evaluate the effect of diet formulated using locally available ingredients and sustainable protein sources such as maggot and snail meal which can be produced easily using readily available by-products.
Three-day old larvae were stocked in 9 plastic tanks (with each of the three treatments replicated thrice) of 85L capacity each filled to the 60L mark. They were subjected to three treatments as follows: Commercial diets throughout the trial (Tcc); Shell free Artemia cyst for the first 14 days followed by maggot and snail based formulated diet (Ta) and maggot and snail based formulated feed throughout the trial (Tlc).
Each treatment contained 2700 old larvae (300 larvae per replicate. The larvae were fed 5 times a day (8:00, 11:00, 14:00, 17:00 and 20:00 at 10% body weight. There was 50% renewal of water daily in all the tanks. At the end of the 60 days experimental period, fish in treatment Tcc recorded the highest weight increase (7.26±0.53g) which differ significantly (P<0.05) from that of treatment Tlc (0.68±0.11g) and treatment Ta (1.75± 0.44 g). Treatment Tcc recorded the highest length increase of 119.05±1.42mm) followed by Ta with length of 39.30±4.01mm. The least length increase was recorded in Tlc (26.66±1.76mm) which did not differ significantly from treatment Ta (39.30±4.01mm).
The best survival rate was recorded in Tcc (41±13) which differ significantly (P<0.05) from that of the other treatments: Tlc (36±6) and Ta (26±7). The specific growth rate was highest in Tcc (5.03±0.01) and Ta (3.85±0.09) and least in Tlc with 3.53±0.05. The best feed conversion ratio was obtained in Tcc (1.15±0.29) and the poorest Tlc (3.16±0.54). The water quality parameters were within acceptable range.
Though Tlc recorded the least SGR and FCR, the survival rate which is one key parameter in the larviculture for the local feed for C. gariepinus was comparable in the three treatments. This showed that with optimal conditioning, the dietary components of the formulated maggot and snail meals based diet may be more available for better performance. or used in combination with live feed, SGR and FCR can be improved.
