Researchers seek help on lobster catches

NIWA researchers are seeking the help of recreational divers, snorkellers and lobster potters in the Hauraki Gulf and Bay of Plenty to learn more about how rock lobster are faring.

Researchers will be stationed at boat ramps in the region at various times for the next five months where they will approach recreational fishers and ask them to participate in a research survey about their catch and effort when targeting rock lobsters.

The area - known as CRA2 – covers a large stretch of North Island coastline from Pakiri Beach near Leigh in the north to Te Araroa on the East Cape. It is an important fishery for commercial and recreational fishers as well as tangata whenua.

The government made cuts to commercial catches last year in a bid to rebuild the rock lobster population in this area, after low stocks were identified. A reduction to the recreational daily bag limit in this area is also under consideration.

Fisheries New Zealand’s Director Fisheries Management, Stuart Anderson says actions were taken to rebuild the fishery in 2018, and this research will further support understanding of the fishery.

NIWA fisheries scientist Bruce Hartill says the purpose of the survey, which begins this month, is to understand whether the lobster population is rebuilding as intended and to monitor changes in recreational harvesting over time.

“It is important we get up-to-date accurate information to enable fishery managers to make decisions on the best data available. What we need to find out is whether recent management measures are working and whether lobster numbers have returned to sustainable levels.”

The researchers have selected 41 days at random until February on which to conduct the surveys that will happen at 12 boat ramps. The survey will continue at the same time for the next five years.

People returning from gathering lobster will be asked by interviewers if they can measure their catch, when and where they’ve been fishing and which methods they used. The interviewers will also ask other fishers to participate in the survey, so the information collected can be used to help manage other species.

Mr Hartill stressed the interviews are voluntary but said the more information the researchers get, the better the data available to Fisheries New Zealand will be.

“Fisheries New Zealand need to understand any changes and trends over time. This is incredibly important information and we appreciate everyone’s cooperation."
