Tilapia culture is practised in tropical and subtropical regions of world and has been growing at an outstanding rate during the past two decades. The worldwide production of tilapia in recent years has increased significantly and this increase has been influenced by the fast expansion of the Oreochromis niloticus species raised in China,Philippines,Thailand,Indonesia and Egypt. Pond culture of Tilapias has received great attention in recent years with Nile tilapia (Oreochromis niloticus) dominating fresh water aquaculture.
This species is preferred due to its;
1 Rapid growth rates
2 High tolerance to low water quality
3 Efficient feed conversion (FCR)
4 Ease of spawning
5 Resistance of disease
6 Good meat taste
Only recently appropriate models have been employed to foster aquaculture growth including development of domestic and export markets for fish in sub Saharan Africa. This made investment in Aquaculture attractive. Freshwater aquaculture production dominates the region where one-third of it's total production is tilapia specially Nile tilapia
Aquaculture industry in Tanzania started in 1940s with experimental ponds at Korogwe and Malya. Like in many other African countries Aquaculture industry was not well productive in the past due to lack of proper management and use of incorrect technology coupled with physical problems such as drought and poor infrastructure. In recent years Aquaculture production started to rise up and it is dominated by Nile tilapia where by small fish scale farmers practise both extensive and semi-intensive aquaculture system.
Growth rate of fish under culture conditions depends much on management species applied during the culture period. The factors which determine growth performance of the fish include species cultured,stocking density,pond fertilization,water quality control parameters and good supplemented.
Nile tilapia and their hybrids are common in mixed sex cultures due to their high growth rates and sometimes may attain a marketable size before commencement of spawning. Feed conversion ratio determined as weight of the feed consumed per weight gained by the fish differs according to experimental conditions, culture system and species differences.
NB.Through good performance of Nile tilapia the fish hatchery centre in Tanzania should be improving inorder to produce good fish seeds for the aim of maintain the current quality of fish cultured by fish farmers in the rural and urban areas which will increase production.
