Collecting biological information - commercial catch

How is the data collected?

The commercial fishing sector voluntarily participates in species-specific monitoring programs in a number of ways. For example:

  • Some commercial fishers assist by notifying Fisheries Queensland about catches and allowing the catch to be measured at a location convenient to the fisher.
  • Some commercial fishers measure fish and collect samples themselves (especially Spanish, spotted and grey mackerel, king threadfin and barramundi) and provide the information to Fisheries Queensland.
  • Many seafood wholesalers and retailers keep fish frames for monitoring, or allow Fisheries Queensland staff to measure fish at their premises, and sometimes to remove otoliths from the fish. Commercial fishers then provide further information about each of the sampled catches (e.g. fishing location and information on any catch sorting that occurred prior to them being measured).

Collecting thorough information on a species throughout Queensland usually requires a combination of the sampling methods outlined above. This is due to differences within the fisheries and marketing for each species and the need to collect information that is representative of the entire commercial catch.
