Understanding Factors Influencing Under-caught TACs, Declining Catch Rates and Failure to Recover for many Quota Species in the Southern and Eastern Scalefish and Shark Fishery

Despite improvements in the status Southern and Eastern Scalefish and Shark Fishery (SESSF) fish stocks, three key indicators of the performance of the fishery have raised concerns:

  • the fishery is failing to catch the TAC’s of many quota species despite historically low levels of fishing effort — at the end of the 2015/16 season, less than 50% of the TAC of two-thirds of quota species was caught;
  • there has been continued decline in catch per unit effort for some species; and
  • there has been a lack of recovery of some overfished species.

These concerns prompted the FRDC to fund this project to investigate a range of potential causes/issues the underperformance of these three indicators.

A range of potential causes/issues of underperformance were evaluated during focussed investigations. This culminating in a workshop to rank the likelihood of potential for each cause/issue to affect each indicator, and to make recommendations to address those causes/issues.
