A New Harvest Strategy for Bass

The Government’s Joint Fishery Statement included two key goals that are at the heart of world class fisheries management:

  1. Protect and improve our fish stocks; and
  2. Manage fish stocks to maximise the benefit to coastal communities.

So what bass stock level will maximise benefits to coastal communities?

One thing is certain, Maximum Sustainable Yield (“MSY”), which maximises only the tonnage of bass that is killed and sold, is not the answer.

  • MSY is recognised by scientists as being economically inferior to the principle of Maximum Economic Yield, so an MSY policy will not maximise benefits.
  • We have seen very clearly the result of using MSY for bass – a disastrous stock crash from which the stock is making a very slow recovery.  Coastal communities are still paying a heavy price for this mismanagement.

Defra has now shared its preliminary thinking on the Bass Fishery Management Plan (“FMP”) and we are very pleased to see that it includes the goal of maximising the benefits of bass fishing for local coastal communities.  However, that goal simply cannot be achieved without the right harvest strategy and Defra’s proposals on this front are far too timid.  They propose starting work in three years’ time (2026) on new research to assess alternative harvest strategies, with no plan for adoption or implementation.

The relationships between stock size and socio-economic benefits for coastal communities are complex and it will take scientists several years from 2026 to investigate these and propose an optimised harvest strategy.  It will then take years for future Governments to adopt and implement the harvest strategy and more years again for the fish stock to grow to the optimal size.  At that rate, we will be stuck with the failed MSY approach well into the 2030’s and probably not achieve the optimal stock size until 10 or 15 years after that.  Are we really prepared to fail on a key goal for the bass fishery and coastal communities for the next twenty years or more?  If so, what is the point of the Bass FMP?

We can do better than this by following the enlightened lead of fishery managers in Queensland, Australia.  They are aiming for a final target of 60% of the unfished stock size (as a proxy for Maximum Economic Yield) by 2027, with an interim target of 40-50% of the unfished stock size as a stepping-stone.

We should do the same.  We know that Maximum Economic Yield gives better economic benefits than MSY, so we should aim now for Maximum Economic Yield while the scientists work on providing an optimised harvest strategy within the next 3 years.

So we are asking Defra to be more ambitious in the draft Bass FMP and to recognise the need for concrete, rapid actions:

  • State firmly that we will move from MSY as soon as possible in order to achieve the goal of maximising benefits for coastal communities.
  • Set an interim goal of a bass stock size of 40-50% of the unfished stock size and ask the scientists to provide an interim harvest strategy to achieve this.
  • Ask the scientists to start working now on understanding the relationships between stock size and socio-economic benefits for coastal communities.
  • Set a date within the next 3 years for adopting a final harvest strategy aimed at maximising benefits for coastal communities.

Let’s put the Bass FMP firmly on track to deliver:

  • a more resilient bass stock that can cope with bad years when fewer young fish survive to maturity.
  • a higher Catch Per Unit of Effort for commercial fishers (so less fuel and time expended) and recreational fishers (fewer “blanks” and more bass per session).
  • higher commercial yields per fish (since the average fish size will be bigger).
  • more of the very big fish that recreational fishers love to catch.
