Project Abstract

Abstract
The study focused on investigating the effect of feeds formulated from local feed stuffs on the growth of Clarias gariepinus, a commercially important freshwater fish species. The research aimed to explore the potential of utilizing locally available feed ingredients to formulate cost-effective and nutritionally balanced feeds for aquaculture production. The experiment involved formulating four experimental diets using various combinations of locally sourced feed ingredients such as maize, soybean meal, fish meal, and wheat bran. These diets were compared with a commercial feed as the control group to evaluate the growth performance of the fish. A total of 120 juvenile Clarias gariepinus with an average weight of 5.0 ± 0.2 g were randomly distributed into five treatments with three replicates each. The fish were fed twice daily at 5% body weight for a period of 12 weeks. Throughout the study, water quality parameters were monitored and maintained within optimal ranges to ensure the well-being of the fish. Growth performance parameters including specific growth rate, feed conversion ratio, and survival rate were measured to assess the efficacy of the experimental diets. The results indicated that the growth performance of Clarias gariepinus varied among the different dietary treatments. Fish fed the diet containing a combination of maize, soybean meal, fish meal, and wheat bran showed comparable growth performance to those fed the commercial feed, with no significant differences in terms of specific growth rate and feed conversion ratio. However, the survival rate was slightly lower in fish fed the experimental diets, although still within acceptable ranges for aquaculture production. Overall, the findings suggest that feeds formulated from locally available feed ingredients have the potential to support the growth of Clarias gariepinus. By utilizing cost-effective local feed stuffs, aquaculture practitioners can reduce production costs while maintaining growth performance. Further research is necessary to optimize the formulation of local feeds and assess long-term effects on fish health and product quality. This study contributes to the growing body of knowledge on sustainable aquaculture practices and the utilization of indigenous resources for feed formulation in fish farming.

Project Overview

INTRODUCTIONAquaculture involves various methods adopted by man in order to improve the natural production of aquatic organisms in an enclosed water body or the rearing of aquatic organisms under semi controlled system.In recent times, there has been great interest in fish farming by both the government and private organizations in the country this may be a reflection of the desire to produce high protein food in the country. However, this noble goal may not be achieved if all the facets of fish culture namely nutrition, desired water quality, breeding seed multiplication and pathology are not understood. In a bid to fight protein deficiency many countries, the world over including Nigeria have been making significant advance in fish farming with nutritional studies as an important aspect.Clarias gariepinus belongs to the family clariadae. This family of catfish is appreciated by consumers for its quality meat (Pruszyriski 2003) it utilized natural food and supplemental feed for fast growth. In addition, it commands high price in the market because of its tastes and texture of flesh. It is recognized by its long dorsal and anal fin which gives it a rather eel like appearance. This catfish has a slender body and flat pairs of barbells. This prominent barbells gives it the image of catlike whistlers.Feed development studies is an aspect of applied nutrition and the zeal for understanding of the nutrition of animal species has been restricted to relatively few species beyond man himself. In U.S.A., the success of channel catfish farming is based among other factors on the nutritional requirements. In Philippines and other far and Middle East countries, agricultural facilities are regular features of the rural economy. In these areas, the development of pelleted balanced diets gave a tremendous boost to the development of the industry (Bardach et al., 1972).Jamua and Ayinia (2003) reported that feed accounts for at least 60% of the total cost of fish production which to a large extent determine the variability and profitability for cheap alternative source of protein that aim to reduce production cost without compromising fish quality. This is so because the dissolved nutrient that promote primary and secondary production in the natural environment are seasonal and might be insufficient or may not occur in required proportions to meet the nutritional demand of cultured fishes (Ugwumba and Ugwumba, 2003). There is therefore the need to develop and encourage fish farmers to make use of locally available nonconventional feed resources (Ibiyo and Olusegun, 2004).In Nigeria, attempts to articulate fish feed studies have been haphazard. Efforts so far, include the work of Dim (1982) on Clarias species; Workers at the Nigeria Institute of Oceanographic and Marine Research (NIOMR) Lagos (Igbinosun et al., 1983) have also been contributing significantly towards the understanding of the requirement of a few species such as Chrysichthys nigrodigitatus. The foregoing research work therefore, underscores the realization the expected role of aquaculture in providing cheap protein food, may not be achieved if we allow our cultured species to depend on the natural productivity of the pond water for growth. Huet, (1972) and Loveil, (1979) appreciated this fundamental fact when they observed that yield usually increased significantly when supplementary diets are fed to fish.Generally, Large Scale aquaculture production facilities would have to contend with several factors which include high investment cost, fish seed and feed supply as well as skilled manpower among other. Of these, it appears that adequate feed supply situation would invariably play a leading role in ensuring an economically attractive return on aquaculture investment. Hence, cheap and high quality feed would help to ensure economical production of table fish with a reasonable period of time.This research work is one of the several effort aimed at developing pelleted feed for C. gariepinus from local feed stuffs. It is hoped that the result of this work would provide illuminating information militating against aquaculture development in Nigeria and form a springboard for further research and development in various aspects of nutrition for C. gariepinus and other related species.1.2 Objective of the StudyTo ascertain which of the protein source (plant or animal) that is better.To determine at what percentage body weights is better to feed the fish.To produce quality feed for catfish C. gariepinus using available local materials at cheap price.
