New fish get into the Adriatic Sea, threatening regional species

F or decades, Croatian fisherman Marko Kristic has actually cast his nets in the carbonated water of the Adriatic Sea. Now an intrusion of the Mediterranean parrotfish is endangering his conventional catch and his livelihood, he states.

Due to environment change and increased maritime traffic, the parrotfish, along with around 50 new types, has actually infected the Adriatic, threatening the native fish population.

Kristic said the parrotfish was very first spotted in the southern Adriatic about 15 years earlier, but it has actually given that become a. common bycatch in his nets.

While delighted in as a delicacy in locations where it is native, the. parrotfish is not to the taste of residents around his village of. Molunat in southern Croatia.

I can't offer it to anybody. The regional population will not eat. this new fish, Kristic stated.

Nenad Antolovic, a researcher for the Dubrovnik-based. Institute for Marine and Coastal Research, states fish stocks in. the Adriatic, the northern most arm of the Mediterranean, have. dropped due to overfishing, environment modification, and the invasion of. brand-new species.

The Adriatic is altering, it is getting warmer. Since of. that, brand-new organisms appear. By (that) I indicate fish and planktons. and algae, Antolovic stated.

According to 2023 information from the Italian National Company for. brand-new Technologies, Energy and Sustainable Economic Advancement. ( ENEA), the Mediterranean is ending up being the fastest-warming sea on. the planet.

New fish species have gotten here in the Mediterranean and the. Adriatic from the Red Sea through the Suez Canal due to warmer. waters or carried in the ballast tanks of ships, endangering the. survival of around 460 native fish species, Antolovic stated.

Some of the new fish are dangerous for people, such as the. toxic lionfish or stonefish.

Last month, an angler from the Dubrovnik location caught a. smalleye squaretail, a deep sea occupant, unusual in the. Adriatic.

In neighbouring Montenegro, scientists from the Institute of. Marine Biology in the seaside city of Kotor singled out the blue. crab as an example of an invasive species.

It got here ... about 20 years earlier and is among the worst. invasive types in the Mediterranean, said researcher Olivera. Markovic.

Anglers and researchers say stocks of shellfishes such as. the green crab have been cut down, and in some places eliminated. completely.

The population of the green crab ... has actually been dramatically. reduced because the appearance of the blue crab, Markovic said.

The rabbitfish, pufferfish and lionfish are growing in. warmer Adriatic waters along the Montenegrin coast, stated Ilija. Cetkovic, a scientist at the institute.

The greatest issue is the lionfish.
