Utility of streamer tags to assess survival and growth of juvenile tiger prawns (Penaeus monodon) in aquaculture environments

摘要: Abstract Experiments in tank and pond environments over 5–6 months showed that growth rate of juvenile Penaeus monodon was unaffected by tagging at 15 mm carapace length (CL) or 18 CL. The mortality prawns tagged CL consistently greater than those both environments, suggesting the minimum size for to obtain less biased survival estimates is least Survival same as untagged animals (40–50%), but (50%) (70%). These results suggest an environment-specific effect on tag-induced mortality: ability independent data from aquaculture ponds allowed be detected. This has been impossible wild fisheries work this paper highlight inadequacy methods prawn populations. Tag colour also tag recovery rates, no mechanism explain bias identified. Streamer tags will prove useful are unlikely affect important performance characteristics marked animals, such rate, reasonable relative among groups can obtained. However, use gain accurate group they meant represent successful, even relatively well-controlled situations, because environment specific effects mortality.
