The ecological and economical impact of the invasive Pacific red lionfish Pterois volitans on native Atlantic communities

Introduction

To invade the marine red lionfish on the native communities of Atlantic can be regarded as among one of the most hazardous introductions of the oceanic fish which has high impacts on the biodiversity of coral reefs. Such predators munch through spacious varieties of native fish and invertebrate species at elevated rates. The venomous spines of those species assist them in avoiding predation and maintain survival. A prospective introduction of the red lionfish is probable to come as an outcome of direct predation, overcrowding, and high competition. Due to such influences, a lot of factors such as climatic changes, and overfishing may lead towards the results which are certainly irreversible and those consequences could adversely impact the industry of tourism and commercial fisheries. The significance of some previous detection it has become an extensively important field to study about the Atlantic communities as the red lionfish are seen far most in the regions of northern Rhode Island alongside the United States eastern coast (Morris, J. et al 2009). Examining and screening is a helpful tool in order to determine when the red lionfish reach towards it carrying capacity for possibly starving a scenario of worst case. A huge amount of red lionfish overlap with a huge minimization of biomasses in several different types of species of red lionfish preys (Green, et al 2012). Due to some probable and possible results which are implicated in societies and economies in totally depend on the oceanic communities of Atlantic.

Biology of the red Lionfish

Lionfish are the spawners of gonochoristic pair that shows a complicated courtship before the release of spawns. In their inhabitant ranging, the courtship of red lionfish occurs abruptly before being mysterious and then expand well in the hours of night times (Fishelson 1975). Till the courtship's end, the female lionfish rises towards the exterior surface and makes release of two masses of eggs from each lobe of the ovary (Morris, 2009). The red lionfish reproduce at a frequency of around 4 days in the Bahamas and North Carolina throughout the whole year (morris, 2009). Such frequency of reproduction equates to a yearly re-productiveness of an approximation of 2 million eggs (Morris, 2009). Such female lionfish mature something like 180 mm of length in total and a male lionfish of white color mature at an approximation of 100 mm of length in total (Morris, 2009). Some invalidated estimations about daily age utilization of otoliths show that the species of lionfish have the natural tendency to become sexually mature in just the first year of life (Ahrenholz & Morris, 2009).

The feed of a mature lionfish is dependent up on about more the forty distinctive species of victim fishes in the Bahamas which includes labrids, small gobiids, grammatids, pomacenrtids, apogonids and some other juveniles such as mullids, larger serranids, lutjanids ...
