Some fleets may have reported having a higher proportion of sailfish than spearfish, not necessarily because there is a higher catch of the first, but because there may be differences in the accuracy of the identification.
Boats engage in strategic gamesmanship in an effort to take "high catch" of the day.
Historically, shrimp trawlers can end up catching 3 to 15 times more bycatch (the unintended catch of fish and other marine life) than actual shrimp, making it one of the fisheries with the highest catch rate of non-targeted species.
Governments consult the scientists who tell them that high catches of fish are sustainable, and ignore more cautious assessments.
In the southern hemisphere Mourato et al. (2014) also reported relatively high catches of sailfish caught with longlines in the southwest Atlantic (South of 20°S), during the spawning season of this species in the austral summer.
quinquefasciatus and nonanal baited traps added with CO2 led to significantly higher catches of Culex mosquitoes [33].
Seamounts showing higher catches of yellowfin (Figure S5) and bigeye (Figure S6) for the whole period 1980 2007 were located between the parallels 10°N and 10°S with Federated States of Micronesia, Papua New Guinea, Solomon Islands and Kiribati (Phoenix Islands and Line Islands) having important seamounts.
The deep-water coral habitats can act as spawning areas for some species and nursery areas for others, as suggested by the higher catches of benthopelagic species (such as the shrimp Aristeus antennatus and Aristaeomorpha foliacea), as well as sharks, hakes, rockfish, greater fork beard, gurnards, and blackspot seabream by long-line in these areas [180], [192].
The crab bottom gillnet and the mackerel gillnet are highly selective, as demonstrated by high catches of the target species.
By ensuring that vessels are kept out of the salmon zone, high catches of squid can be maintained, while minimising the salmon by-catch.
