2.1.1 Native A. regius vs. Invasive S. commerson A native meagre in the Eastern Mediterranean, A. regius, was one of the most common commercial fish in Israel. However, this species has since disappeared from local catches, while interestingly, the Lessepsian migrant mackerel S. commersonhas has dramatically increased in population. Studies have been done on this occurrence, and it has been theorized that, due to similar life histories and diets, this may be an example of an invasive migrant outcompeting a native species and occupying its niche[3]
 * In the interest of making this paragraph more encyclopedic I would remove “while interestingly.”

Eight species of invasive prawns from the Erythrean Sea have been recorded in the Eastern Mediterranean. These prawns are considered highly prized to the Levantine fisheries, and compose most of the prawn catch off the Mediterranean coast of Egypt, being 6% of total Egyptian landings.[4]However, this high abundance of invasive prawns has lead to the decline of a native penaeid prawn M. kerathurus, which supported a commercial Israeli fishery throughout the 1950s. Due to out competition and its habitat being overrun by these migrants, this native species has since disappeared, having a detrimental impact on the commercial fishery.[5]


 * Change ‘lead’ to ‘led’
 * These prawns are considered highly prized to the Levantine fisheries, and compose most of the prawn catch off the Mediterranean coast of Egypt, being 6% of total Egyptian landings.

Might rearrange sentence structure: A highly prized species of the Levantine fisheries, prawns make up most of the catch off the Mediterranean coast of Egypt, representing 6% of total Egyptian landings.

The goldband goatfish, Upeneus moluccensis, was first recorded in the eastern Mediterranean in the 1930’s and has since established an abundant population. Following a warm winter of 1954-1955, it increased to 83% of the Israeli catch, replacing the native red mullet, which also effected the Egyptian fishery, being 3% of their total landings.[6] The high water temperatures of this unusually warm winter may have resulted in the poor survival of red mullet juveniles, which may have allowed the goatfish population to expand into this opened niche.[5] Native mullet have since been displaced into deeper, cooler waters, where it has been found that Lessepsian migrants consist of only 20% of the catch, whereas in shallower, warmer waters, these invasives take up a staggering 87% of the catch.[5] From this data, it is apparent that the Lessepsian migrants have not adapted to the more temperate environment of the deeper areas of the basin, but have established dominant populations in the habitats most similar to the tropical sea habitats from which they came.


 * …Following a warm winter of 1954-1955... –consider changing to “following a warm winter during 1954 and 1955, the population increased to…”

–Despite the fact that this is a very educated and well-formed likely explanation/hypothesis Wikipedia doesn’t like scientific hypothesis in their articles unless they are widely proven and completely definitive.
 * “The high water temperatures of this unusually warm winter may have resulted in the poor survival of red mullet juveniles, which may have allowed the goatfish population to expand into this opened niche.”
