The fishing industry is the second most profitable after agricultural industries in coastal areas especially. Fishes are caught in bulk and the rare ones, though protected are still caught illegally as delicacies. Fishes like salmon and sardines are used for food and their breeding capability is quite high which is gradually reducing due to presence of toxic substances in water. But unfortunately due to bycatch problems, even non-edible fishes are caught which are killed by fishermen. Pollution is another major factor. Overfishing should be controlled though that will take sometime as the government has to feed large masses. But nowadays, fishermen do not want to work under government-run fisheries as it is not very profitable for them. They use their own fishing boats which accounts for the fastest reduction of fish populations all over the world.
The fish population is declining due to overfishing, habitat destruction, and pollution. Conservation efforts and sustainable fishing practices are needed to help stabilize and increase fish populations.
Extinction of species, since the fishing methods are tailored to the way the species behave. Killing of unintended species.
The fastest known species of fish is the Atlantic Sailfish (Istiophorus albicans) at 68 mph but is closely followed by the Indo-Pacific Sailfish (Istiophorus platypterus).
Europe's countries are mainly declining in population and GDP.
if a species is declining then the species that eats that one has less food and will decline fast as well
The fastest water animal is the dolphin, but the fastest fish is the sail fish, not a sword fish.
It has been placed on the list of endangered species.
because there are no fish
Declining fish populations in Scandinavia can be attributed to overfishing, habitat loss, pollution, and climate change. These factors have contributed to the depletion of fish stocks and disrupted the marine ecosystem, leading to a decline in fish populations in the region.
The world's fastest mammal, the cheetah, can reach speeds of up to 70 miles per hour, while the world's fastest fish, the sailfish, can swim at speeds of up to 68 miles per hour. Therefore, the cheetah is faster than the sailfish.
No, there are thousands of species of fish.
Most sources believe that the fastest recorded speeds of saltwater fish have been achieved by Swordfish and Blue Marlin, both of which have been observed to be able to swim at 80mph, especially when being persued by shark predators. The second fastest record belongs to the Sailfish, which has been known to hit 60mph. Swordfish, sailfish and marlin are all related species.
