I often drop by Avaaz to see what I can sign and seen these two you might care to sign:
Go forth and sign!
Here’s a great little animation explaining briefly but accurately the EU Common Fisheries Policy. I particuraly like how they show how politicans use logic, reason and scientific data to generate sustainable species quota.
As usual, it’s all politics. So be sure to know where your politician lies on the serious issue of overfishing!
Here is a bit on Sottish fishermen, about to test a new net which may slash bycatch in Nephrops (Dublin Bay Prawns) catch by 70%
I wish them well, any potential mechanism trying to reduce bycatch should be welcomed with open arms, as I’ve discussed before!
Another positive is that the net was designed with by the fishermen themselves, which is fantastic! There is great contention between fishermen and fishery scientists. Fishermen insist scientists have to go out on the fishing boats to see what’s how much fish there is, while scientists (who do spend time trawling!) insist fishermen are, with bias judging there to be much greater stocks than there are.
There is a little fault on both side of course but I’m not getting into that here as I’m meant to be studying for exams.
The EU Common Fisheries Policy
The framework for ﬁsheries management in the EU is now set out in Regulation 2371/2002 under the Common Fisheries Policy (CFP) (European Council 2002). Since the 1970s, a variety of instruments have been employed to curb overﬁshing or to prohibit damaging practices and yet a growing number of commercial ﬁsh stocks in European waters are considered to be outside safe biological limits (Stokke et al. 2004).
The CFP uses two types of instruments to conserve fish stocks within its jurisdiction: total allowable catches (TACs) which set upper limits for the total amount of fish which can be landed from particular areas; and technical measures including gear regulations, closed seasons, closed areas, and minimum allowable sizes for individual species (Daw et al. 2005), in addition the policy attempts to limit fishing effort by controlling the capacity of fleets (structural measures) and limiting time spent at sea. The establishment of these measures is based on scientiﬁc assessment of the status of stocks.
Working groups of scientists within the International Council for the Exploration of the Seas (ICES) coordinate and report on research, which is then discussed by the ICES Advisory Committee on Fishery Management (ACFM) and used to produce scientiﬁc advice for the European Commission (Daw et al. 2005). Currently EU legislation designates TACs for each species. The TACs are divided between member states. Each state then allocates quotas to fishermen and fishermen co-ops.
The main intension of this legislation is to conserve stocks. Legislation dictates that any fish caught below minimum landing size or any fish that exceeds the designated quota, must be discarded. It is illegal to land fish exceeding quota limits or outside size limits.
Summary of discards and current discards policy
A huge problem with the current CFP is the wasteful discards policy in place. In its most simple form, discarding is the routine throwing overboard of unwanted or unlandable catch. A more succinct definition given by the Food and Agriculture Organisation (FAO) states discards to be “that proportion of the total organic material of animal origin in the catch, which is thrown away, or dumped at sea for whatever reason. It does not include plant material and post harvest waste such as offal. The discards may be dead or alive” (FAO 2005).
International changes to discards policies
The Canadian Government banned discarding in its Atlantic Groundfish fishery it is now illegal to discard any groundfish except those specifically authorised and those caught in cod traps. In addition to the banning of discards larger vessels are required to carry observers which would imply that there are now no illegal discards on these vessels (Clucas, 1997).
In Iceland the government introduced an Individual Transferable Quota system (ITQ) where a species specific Total Allowable Catch (TAC) is put forward (in weight) for a period of time, the ITQ system was followed by a ban of at-sea discarding of catch (Clucas, 1997).
The combination of these two measures, will ensure the retention of species over their quota but which still have a market, as it is mandatory to land small fish too, there are upper limits on the percentage weight of fish that can be landed below minimum landing size, ergo, discouraging the capture of smaller fish.
The Faroe Islands and Greenland adopted very similar regulations to that of Iceland. The Norwegian government introduced a ban on the discarding of some commercial species of fish in mid 1990 (Clucas, 1997). The Norwegian system of attempting to reduce mortality of illegal fish based on reducing their capture rather than reducing landing of “illegal” specimens (Løbach 1996).
Consequences of discarding
All marine fauna caught and discarded have usually only a very small percent chance of survival. The discard mortality of all fish species caught in the Nephrops fishery is estimated at 100% with Nephrops discard mortality estimated at 75–100% (Evans 1994).
The level of discard mortality depends on species characteristics, catch composition and haul duration (Lindeboom 1998). Organisms killed as discards, are lost as future potential income for fishermen, future spawning stock biomass and killing and returning fauna to the sea alters the ecosystem dynamics, but also providing food for benthic detritivores e.g. arthropods.
Possible alterations to the current discards policy
The current discards policy is showing to be extremely wasteful, and though it has theoretically reduced EU fish landing to represent a somewhat safe biological limit, the policy ignores the huge mass of discards and bycatch killed in the process.
In the North Sea for example; the flatfish beam trawl fishery, the discarded invertebrates; whelks (Buccinium undatum), starfish (Asterias rubens, Astropecten irregularis) and crabs (Cancer pagurus, Corystes cassivelanaunus, Liocarcinus holsatus) have estimated discard mortalities of 0, <10 and 60–70%, respectively (Lindeboom 1998).
The total annual quantity of discards discharged into the North Sea alone is estimated at 800,000–950,000 tonnes (Tasker 2000).
Many of the important commercial stocks (e.g. North Sea cod Gadus morhua) have suffered serious declines and are threatened with collapse; management measures have proven ineffective; and the European ﬂeet has not successfully been downsized to an appropriate capacity to exploit the dwindling resources (Gonzales Laxe 1999).
The current consensus of European fisheries scientists and managers is that improved selectivity of fishing gear will not sufficiently improve the state of stocks, and that this objective can only be achieved by a reduction in fishing effort (Catchpole, T.L. et al. 2004).
The European Fisheries Commission believes that the most important contribution towards reducing discards is through the improvement of North Sea fish stocks (Anon 2002); stating a reduction in exploitation will improve stock conditions and fish survival, though does not explain how discards will be reduced.
One of the most obvious ways one could reduce discards is to reduce fishing effort, however this has an immediate knock on effect to the fishermen, effectively reducing their catch solely to reduce discards. This method may encourage fishermen to be more diligent and selective in their fishing practices e.g. use of selective gear or inversely cause some fishermen to be less selective, catching as much as possible and keeping the better specimen and or high grading their catch.
With unchanged rates of discarding, an increase in discards will follow any increase in fishing effort or increase in fish abundance; thus, fishing effort controls do not provide a long-term solution to the discard problem (Catchpole, T.L. 2004). However, if one were to restrict the number of permissible fishing days per season and completely ban discarding the fisherman could compensate the loss in fishing days with the non-discarded fish, reducing overall fishing effort with no discards at all.
Furthermore the incorporation of selective gear could further increase the survival of juvenile, young and non-target species. Over a period of some years gear selectively could be increased, this would further allow species e.g. cod, survive to a reach a greater age and spawn several times over their lifetime.
The CFP is up for review in 2012, and recently there has been a big push to cut the current discards policy from future policies.
