There are dozens of fish breeds that are taken to distant lands for cultivation. Be it local species or a race that is rare and on the verge of extinction. When these fishes breed in foreign waters, having a variable temperature and habitat, these breeds turn invasive and try to dominate its surroundings. This results in the local fishes of the foreign land relocate from the area. The invasive peacock bass is one such breed that affected domestic breeds in Thailand, Panama, and significant countries in South America.
Invasive Peacock Bass: The Overview
Cichla Monoculus is one such brand exported across the world for easy consumption. It is known by it’s the common name: Peacock Bass. They easily fell prey to fishermen’s baits and caught quickly. However, due to their capacity to breed speedily, they occupy and expand their survival area in the waters. They are excellent predators and consume native fishes around them. This often raises a considerable hue and cry near the coasts where the peacock bass breed.
This breed is invasive by nature and can cost a fortune if they predate native stocks. An experiment by researchers in South American lakes threw light on this predating concept. A lake completely free from invasive peacock bass was abundantly filled with it. After a certain period, the study revealed that the native fishes were nowhere to be found inside the waterbody.
The Experimental Analysis
Specialists thought about the quantities of local species in two lakes attacked by peacock bass, Gatun, and Alajuela, with the amounts of local species found in Lake Bayano, a waterbody completely free of peacock bass. In spite of facilitating other obtrusive predators, similar to Parachromis managuesis, a form of Cichlid. The Lake Bayano has a more prominent stock of local fish. Now that the issues have come to light, the local authorities are taking care of the breeding of the peacock bass in these waters. Any connected waterbody is not independent of inhibition of other kinds of fishes. However, manned waterbodies have a lesser chance of being infiltrated by predating breeds that destroy the local marine culture.
Fish anglers in Asian waters see the peacock bass as an imminent threat to their fish breeds. According to them, there is a negligible consumption of fishes like Cichlid in Malaysia, the Philippines, and India. However, local fishes consumption is very high in these places. Therefore local mariners cannot afford to let predating fishes into their waterbodies. They see it as a live weapon bent on destroying their livestock.
Similar Cases of Predating
Other cases where foreign fishes eat away the local ones are also there. The invasive peacock bass is not the only breed to do so. In the 1980s, Nile Perch breeds were the cause of extinction of 500+ endemic cichlid fish in Africa. Nile Perch is also known as Lates niloticus, and this incident happened in the popular Lake Victoria. However, these fish breeds are interesting. A lot is unknown about them. Significant researches will reveal later on.
