Countries involved in bluefin tuna fishing have decided to do more to protect a species of shark against collateral killing, environmental groups said Saturday.
Elizabeth Griffin Wilson of the Oceana group said the 48-state International Commission for the Conservation of Atlantic Tunas (ICCAT) had ruled that tuna fishermen who find a silky shark in their nets must put it back in the sea.
The only exceptions should be coastal communities who hunt the shark for consumption, she said.
Wilson hailed the move, saying studies had shown the silky shark to be highly vulnerable to long-line tuna fishing in the Atlantic.
The US Pew Environment Group also praised the decision, while deploring the fact that another shark, the porbeagle, was not similarly protected.
Marine protection groups claim that three-quarters of migratory shark species that inhabit bluefin fishing areas are threatened with extinction.
Pew wants fishermen to use new materials that allow sharks to escape, such as nylon fishing lines that can be severed by a shark but not a tuna.
ICCAT has been meeting in Turkey to discuss ways to put tighter controls on catches of the endangered fish, savoured by sushi eaters for its firm meat.
One decision was to introduce an electronic tracing scheme for catches to replace the returns on paper which environment groups say is open to widespread fraud.
ICCAT also cut from 20 metres to 12 metres the size of boat which must undergo a mandatory inspection of its bluefin haul on return to port, Pew said.
But the WWF condemned as weak and insufficient a decision to set the minimum size of swordfish allowed to be caught at 90 centimetres (three feet).
Small steps for tuna, sharks and swordfish

Measures to prevent illicit fishing of Mediterranean bluefin tuna have been strengthened at the annual meeting of governments involved in the industry.
The International Commission for the Conservation of Atlantic Tunas (Iccat) decided to implement an electronic system for recording bluefin catches.
Research shows catches have been far higher than skippers have declared.
The meeting, in Turkey, also gave extra protection to the silky shark, whose numbers are falling because of fishing.
Tuna boats often snare this species by accident; and now, fishermen will have to release them alive.
Government delegates also voted through a minimum legal size for swordfish, and will draw up a comprehensive recovery plan in 2013.
But proposals for protecting the porbeagle shark, classified as vulnerable to extinction on the internationally recognised Red List, were rebuffed.
The most controversial issue on the agenda - illegal fishing for the lucrative bluefin in Libyan waters during the height of this year's civil conflict, which BBC News revealed earlier this month - will be addressed in a separate meeting next year.
Conservation groups gave a mixed reception to the outcomes.
"Iccat's new bluefin tuna electronic catch documentation scheme is an important and positive leap forwards in the monitoring of the fishery and protection of the species," said Sergi Tudela, head of fisheries for WWF in the Mediterranean region.
A report from the Pew Environment Group last month showed that last year 140% more bluefin meat entered the market from the Mediterranean than was declared, largely because the paper-based catch recording system was open to abuse.
The new system will not, however, track bluefin through the "farms" or "ranches" where they are fattened for eventual sale, usually to Japan.
"The continued absence of data on quantity and size of bluefin tuna caged in fattening farms creates a black hole and provides an easy facility for the laundering of illegal, unregulated and unreported catches of Mediterranean bluefin tuna," said Dr Tudela.
Although the focus of Iccat meetings is often on the Mediterranean, the body also regulates fishing across a huge swathe of the Atlantic Ocean.
This includes waters off the west coast of Africa which are beginning to see heavy fishing.
Here, Iccat governments voted to restrict the use of fish aggregating devices (Fads) which attract tuna and sharks, and whose use often leads to significant catch of unwanted species and juveniles.
The Istanbul meeting also produced some good news for birds in the south Atlantic.
Longline boats, which tow lines tens of kilometres long carrying thousands of baited hooks, will have to use at least two out of three methods proven to reduce the accidental catch of albatrosses and other ocean-going giants.
The three strategies comprise deploying streamers from the back of the boat to scare birds away, setting lines at night, and adding weights to their hooks so they sink too deep for the birds to reach.
"This is a great day for albatrosses and other seabirds which die needlessly every minute of the day, accidental casualties in the tuna and swordfish fisheries," said Dr Cleo Small of the RSPB and BirdLife International.
