spanish scientists have studied interactions(相互作用,相互交流) between the loggerhead turtle (caretta caretta赤蠵龟) and fishing gear(钓鱼用具,打捞用具) such as longline hooks used at the water surface, mass beachings, and the effects of climate change on these animals. in order to reduce captures of this 1 species without causing economic losses for fishermen, the scientists are proposing that fishing in the summer should only be carried out by night and in areas more than 35 2 miles(海里) from land. populations of loggerhead turtles (caretta caretta) are in decline all over the world, and particularly in the 3 sea, where more than 20,000 animals are accidentally caught each year. finding responsible and sustainable fisheries(渔业) solutions was one of the prime objectives of this research study, published in the latest issue of the journal of 4 ichthyology(应用鱼类学) .

researchers from the spanish institute of oceanography (ieo) in malaga, the university of malaga (uma) and the sea classroom, also in malaga, tested whether using different kinds of animal bait(饵,诱饵) would reduce captures of loggerhead turtles, and how these changes could impact on fishing yields(生产量) .

the scientists used real commercial fisheries data taken by scientific observers on board fishing boats. the results were clear. "using fish as bait could greatly reduce incidental catches of loggerhead turtles, but could also 5 affect catches of swordfish(箭鱼) ", josé carlos báez, lead author and a researcher at the ieo, tells sinc.

the research team also showed that stopping using small molluscs(软体动物) such as squid(鱿鱼,乌贼) as bait could not ensure that incidental(偶然的,附带的) catches of loggerhead turtles would be prevented, since "as an opportunistic 6 it also 7 on hooks baited with fish, and can find these more easily when molluscs are used", explains the expert.

the study proposes other measures that, the researchers say, would not involve modifying the equipment used in any way that "could result in low economic yields because of a decline in fish catches", says báez. these techniques would reduce the number of turtles caught while maintaining fishermen's profits.

"most accidental catches happen during the day, more than 35 nautical miles from the coast, and in the summer, meaning that it would be enough to limit longline fishing at these times and places in order to drastically reduce captures of this species", says báez, who adds that these measures should be tested before being adopted.

longline fishing is practised by 356 8 in spanish waters, and provides employment for many 9 towns. however, accidental captures of species such as the loggerhead turtle are also damaging to fishermen's interests, because of the economic losses caused and the time spent in freeing the turtles.
