In females and males, the body is gray or yellowish in color and has 3-4 black spots along the sides of the body. Attempts to produce viable tetraploids that could then be used to mass-produce triploids in crosses with normal diploid fish have, to date, not met with success. Genus: Oreochromis Female fishes of this genus keep their eggs in their mouths for hatching. WebThe purpose of this study is to investigate the economic value of fish (Nile Tilapia) in Lake Hawassa and determine the factors affecting the households willingness to pay for a quality improved fish product.

Psychological health, Strengthening bones, Combat cancer cells, Cardiac health, Assist to lose weight. The scrap from canneries, as well as entire fishes that are not relished by man, are dried and ground in mill. Recent advances in molecular genetics are likely to provide tools that can enhance traditional selectivebreeding methods. The O. niloticus O. aureus hybrid often produces inconsistent sex ratios, and broodstock contamination can lead to further deviations from predicted sex ratios. Commonly, new introductions of tilapia take place with relatively small numbers of fish leading to strong founder effects. Tilapia is now the third most important fish in aquaculture, providing around 1.5 million metric tonnes per year. Above all man can digest it easily. There are numerous so-called strains of tilapia throughout the world, and several are promoted as having particularly desirable traits for aquaculture.
