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