Effects of water movement and aeration system on the survival and growth of hatchery bred sugpo (Penaeus monodon Fabricius) in earthen nursery ponds

Abstract

An experiment was conducted to determine the effects of water movement and airlift aeration on the survival and growth of P. monodon fry reared from P₄P₅ to P₃₂P₃₃ in earthen brackishwater ponds. The high survival rates obtained justify the need for aeration when using the earliest stages of fry (P₄P₅) at higher stocking densities. For older stages regardless of source and at lower stocking densities, nursery operations based on traditional methods could also achieve better survival rates.
