Aquatic Species Versus Terrestrial Livestock
Selective breeding programs for aquatic species provide better outcomes compared to terrestrial livestock. This higher response to selection of aquatic farmed species can be attributed to the following:
- High fecundity in both sexes fish and shellfish enabling higher selection intensity.
- Large phenotypic and genetic variation in the selected traits.
Selective breeding in aquaculture provide remarkable economic benefits to the industry, the primary one being that it reduces production costs due to faster turnover rates. This is because of faster growth rates, decreased maintenance rates, increased energy and protein retention, and better feed efficiency (Gjedrem and Baranski 2009). Applying such genetic improvement program to aquaculture species will increase productivity to meet the increasing demands of growing populations.

Famous quotes containing the word species:
““If Steam has done nothing else, it has at least added a whole new Species to English Literature ... the booklets—the little thrilling romances, where the Murder comes at page fifteen, and the Wedding at page forty—surely they are due to Steam?”
“And when we travel by electricity—if I may venture to develop your theory—we shall have leaflets instead of booklets, and the Murder and the Wedding will come on the same page.””
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
