“…Catfish is a fatty fish and is of importance to human health. In addition, catfish are highly resilient, being able to survive poor water quality and can be transported live to the market; they can also be preserved as smoked product (Anetekhai et al, 2004). Presently fish feed alone account for between 60 and 75% of the total cost of fish production (Babalola, 2010).…”

This study investigated the effects of dietary palm oil (PO) on growth performance and carcass composition of Heterobranchus longifilis with the goal of replacing dietary fish oil with palm oil. In this study triplicate groups of H. longifilis fingerlings were fed the experimental diets for 8 weeks. Five isonitrogenous (45% crude protein), isoenergetic (20 KJg-1) experimental diets were made containing either 6.0% FO and 0% PO, 4.5% FO and 1.5% PO; 3.0% FO and 3.0% PO; 1.5% FO and 4.5% PO; or 0% FO and 6.0% PO using soybean and fish meal as the protein source. Dietary palm oil had no significant effect on growth rate or feed conversion ratio. Similarly, No significant differences were observed between dietary treatments for moisture, protein and ash content in H. longifilis fingerlings. However, fillet saturated, monounsaturated fatty acids and liver lipid deposition were significantly (P<0.05) higher in fish fed 6.0% PO diet. This study suggests that the replacement of cod liver oil by palm oil as lipid supplement in the diet permitted a clear improvement of growth and FCR of H. longifilis. This indicates that PO can effectively replace FO in the diet of the fish without compromising fish growth and feed efficiency.

“…Thus freshwater aquaculture is the most promising avenue to increase aquaculture production in the short and medium term. Anetekhai 2 reported that freshwater aquaculture is the most understood form in Africa, but that the inadequate and expensive feed is one of the major factors affecting poor performance, as described later. The dominant countries of freshwater aquaculture are Egypt and Nigeria.…”

World aquaculture production in 2002 reached 39.8 million metric tons (Mt). However, despite a general understanding that the advancement of aquaculture is very important for food security and poverty alleviation, aquaculture in Africa is insignificant compared to the rest of the world. African aquaculture contributed only 1.2% (463 × 10 3 Mt) of world aquaculture production. Moreover, our calculation based on FAO statistics revealed that the average per capita consumption of fish in Africa decreased from 9 kg in 1990 to 7.8 kg in 2001. This decrease in the per capita consumption of fish appears to be a threatening sign for food security in Africa. There are many political, economic and technical issues that are obstructing the development and promotion of aquaculture in Africa. Egypt, the desert but rice producing country, has a long history of aquaculture and is the leading producer, especially of freshwater aquaculture in Africa. Total aquaculture production in Egypt in 2002 was 376 × 10 3 Mt, which supplied 81% of that in Africa. In the present review, based on the case of Egypt, we propose measures and research areas to develop and promote rice-fish culture and desert aquaculture. Rice-fish culture is a model of aquaculture styles for wet and pluvial regions, and desert aquaculture is also a model for arid and semi-arid regions not only in Egypt but also for other African countries. Poor knowledge on fish feeds and feeding technology is one of the major constraints in the expansion of aquaculture. In order to improve and increase the productivity of aquaculture in Africa, we propose measures and research subjects for developing supplementary and complete feeds using regional ingredients.

“…Fish production from aquaculture ranges from 15,840 metric tonnes in 1991 to 25,720 mt in the year 2000 and 86,350mt in 2009 [9]. Production varies from 0.5mt/ha in small scale to 10mt/ha in large scale for earthen ponds and this largely depends on level of management intensity [10]. Tilapia and clariid are the most culturarable species in Nigeria.…”

As the global population increases, demand for food, most especially protein will increase. Production from fisheries is crucial for food security in the face of current population increase. Despite the reliability on fisheries and aquaculture to supply the animal protein needed by the world population, climate change has significantly reduced production and increase instability in the sector. In order to achieve food security and fisheries development goal, climate smart aquaculture which is an adaptation to climate change and lower emission intensities per output will be necessary. This review therefore discusses climate smart aquaculture as veritable approach to increasing fish production in the face of climate change trend in Nigeria. A number of changes already evident can be attributed to climate change; drastic change in weather condition, reduction in water levels, changes in hydrological regimes of inland water, heavy wind storm, excessive sunshine, increased incidence of flooding and drought. The effects of these changes have resulted in changes in ocean fish productivity, fish disease infestation and reduction of production from inland and aquaculture systems. Climate smart adaptation and mitigation strategies has helped to increase the resilience and adaptive capacity of communities and ecosystems, examples of such strategies include adopted strategies in the Niger-Delta region of Nigeria where about 80% of fish farmers were reported to have adopted strategies such as use of tarpaulin/tank ponds during dry weathers, about 70% have adapted by adjusting time of stocking while 60% stocked fish species that can better adapted to climate change impacts. Other adaptations strategies include erection of cover/shades over ponds, digging boreholes/wells to supply water during dry weathers and well-structured drainage system to guide against flooding. Integrated aquaculture is also an important adaptive measure which has gained huge popularity in Nigeria. The use of low carbon producing energy source in the production and processing of product from aquaculture is a viable means to mitigate against climate change, example include the use of gas or electricity rather than charcoal in fish smoking. Aquaculture waste water treatment before discharge is also a good mitigation practice been recently developed. Climate change will have significant impacts on fisheries and aquaculture in Nigeria. Climate smart aquaculture will respond to these changes by boosting adaptive capacity and resilience both of communities and the ecosystems on which they depend. It is important therefore to ensure adaptation and mitigation in response to climate change so as to safeguard sustainable fish production and food security improvement. effects of these change has resulted in elevated water temperatures [3], which affects fish physiological processes, thereby affecting spawning, survival of the juveniles, recruit into the exploitable phase of population, population size, production and yield [4]. The impacts of increased flooding of ...
