Scientists are looking for ways to prevent the complete extinction of dolphins
Since the beginning of 2019 on the French coast threw 1.2 thousand dead dolphins. The bodies of many of them had wounds, suggesting that the animals were killed, caught in fishing nets. About it writes TCH.
The number of dead dolphins could be much higher, since, according to estimates of biologists, for every dead Dolphin that are brought to shore, accounting for at least a few animals whose bodies remained in the water. Thus, less than six months of 200-thousand population of dolphins inhabiting the Bay of Biscay, could have been killed about 6 thousand.
Scientists believe that the mass death of dolphins caused by fishing, namely, the unintentional catch of dolphins, falling along with other inhabitants of reservoirs in the network apart. According to scientists, the dolphins fall into the fishing nets due to restrictions on the catch of a flounder. Because this fish lives at depth, the grid had to be increased above, what they have begun to get dolphins.
“This could have disastrous consequences. Dolphins inhabiting the Bay of Biscay, reach sexual maturity at the age of 8 years and can live to 25. The females give birth to cubs once every three years. To restore the population of animals in case of its rapid decline will not be too simple,” the article reads.
Now trying to save the animals as activists and the leadership of France. The conservancy Sea Shephers patrolling the Gulf on Board his vessel the MV Sam Simon and record the number of trawlers and dead dolphins. Their constant presence is not like the local fishermen.
“Sea Shepherd are fighting with people who hunt whales in Japan, and it is good, however, as they haunt us when we work and put pressure on us, ordinary fishermen, simply because the network some of us sometimes get dolphins? It is incomparable,” said 75-year-old Jean Lagarde, one of the oldest fishermen of La Rochelle.
However, the Chairman of the French Department of Sea Shepherd Lamia was Essemlali believes that these efforts are insufficient and calls to attract more independent observers and to install cameras on Board fishing vessels. And some activists offer to install fishing nets acoustic repellents that will play sounds, scaring the dolphins.
