Some terms

Biomass (B) is the weight of the fishes in the sea

Fishing mortality (F) is an indicator of the proportion of fish killed by fishing

MSY is the maximum sustainable yield

Bmsy is the biomass that can produce MSY

Fmsy is the fishing mortality resulting in MSY and Bmsy

Blim is the biomass below which recruitment is reduced and collapse possible

Bpa is a biomass slightly above Blim but far below Bmsy (Bpa ~ Bmsy-trigger)

Legal Background

The UN Convention on the Law of the Sea (UNCLOS 1982), Article 61(3), requires that coastal State fisheries

management measures in the EEZ must aim at restoring and maintaining fish stock biomass that can produce

maximum sustainable yields.

The United Nations Fish Stock Agreement (UNFSA 1995), Annex II, specifies that after the rebuilding phase, Fmsy is to be used as a limit reference point.

The precautionary principle, as contained in the Treaty on the Functioning of the European Union, Article 191(2) and in UNFSA Article 6, demands that „States shall be more cautious when information is uncertain, unreliable or

inadequate. The absence of adequate scientific information shall not be used as a reason for postponing or failing to

take conservation and management measures.“

Biomass of European Fish Stocks

Average size of European fish stocks (bold blue line). The upper arrow indicates the path, if 75% of the stocks were to reach the Johannesburg target in 2015. The lower arrow shows the current trend.

Fishing Mortality of European Fish Stocks

Average fishing pressure on European fish stocks. The lower arrow indicates the path if 75% of the stocks were to be fished at the maximum sustainable rate in 2015. However, with the trend since 2000, that target will be missed by more than 30 years.

Why Should Europe Care about Global Fisheries?

42% of the global trade in fish and fish products is imported by the Europe

A CFP reform that correctly implements UNCLOS and UNFSA, such as done by USA, NZ and AUS, will force others to follow

A failed CFP reform will encourage continued overfishing, in Europe and globally

US$ 1.2 billion European fish exports into the USA will be endangered

Generic Harvest Control Rules for European Fisheries

Rainer Froese, Trevor A. Branch, Alexander Proelß, Martin Quaas, Keith Sainsbury & Christopher Zimmermann

FISH and FISHERIES 2010

Nine simple rules for European fisheries management resulting in 1) Economic optimization of the fishery

2) Adherence to UNCLOS and UNFSA

3) True implementation of the precautionary principle 4) Building on international experience

5) Progressing towards ecosystem based management 6) Compatible with the biology of European fish stocks

• Under these rules, stocks can be four times larger and

catches 63% higher, on average, compared to current levels.

(14)

HCR 1: Reference and Trigger Biomass

The reference biomass Bmsy for the subsequent rules and reference points is the biomass that can produce the maximum sustainable yield.

This biomass also acts as a trigger when stocks fall below this level.

Froese et al. 2010 Fish and Fisheries

(15)

HCR 2: Target Biomass

The target biomass, to be achieved on average over approximately 5 years, is 1.3 Bmsy.

The target biomass can be increased as

required by economic, ecosystem or other considerations.

Froese et al. 2010 Fish and Fisheries

(16)

HCR 3: Limit Biomass

The limit biomass Blim, which is to be avoided with a high probability, is 0.5 Bmsy

A higher biomass limit may be set for species with low resilience to exploitation.

Froese et al. 2010 Fish and Fisheries

(17)

HCR 5: TAC Reductions

If the biomass falls below Bmsy, then the TAC is linearly reduced, as a function of biomass, to reach zero catch at Blim.

Froese et al. 2010 Fish and Fisheries

(18)

HCR 9: Size structure

The mean size and age in the catch will be

adjusted to minimize changes in age structure caused by fishing and to reduce the effects of fisheries-induced unnatural selection.

Status of European Stocks

Move stocks here.

Landings may then be 63% higher from 4 times larger stocks

Making a Miracle Come True:

Three Options for Rebuilding the Cod Stock in the Eastern Baltic Sea

Rainer Froese & Martin Quaas

We compared a request by fishers with current management and with the rules proposed by Froese et al. 2010

The rules would rebuild and maintain the stock above Bmsy and provide the highest profits over the next 10 years

Investing in the Resource is Smart

Conclusions

• Getting the CFP reform right is of European and of global importance

• European fish stocks are underperforming assets

• Investing in larger stock sizes leads to

improved ecosystems status, healthy stocks, healthy fisheries and healthy profits
