Twenty-three seabird species used food made available by fishing operations. Mean number of species recorded per day varied between 2.5 and 6, depending on the fishery and was significantly lower in the Bahia Engafio area. The highest number of species (17) was observed at the Golfo San Matias area. Kelp Gulls (Larus dominicanus) and Black-browed Albatrosses (Diomedea melanophris) were the most important seabirds, both in frequency of occurrence and numbers, followed by White-chinned Petrels (Procellaria aequinoctialis) or South American Terns (Sterna hirundinacea), depending on the fishery. Kelp Gulls were present between 91.6 and 100% of days at all fisheries except for Bahia Grande (28.6%), with numbers which varied between a few and 600 birds (means between 148.2-178.8 birds). Black-browed Albatrosses were present between 92.2 and 100% of days at all fisheries except for Bahia Engafio (7.3%), with numbers that varied between one and 375 birds (means between 53.7-123.7 birds). Most other species were either present in small numbers or were rarely observed. Seabirds obtained prey during discarding activities or from the net. Seabird mortality as a result of incidental captures was very low, with only one Imperial Cormorant (Phalacrocorax atriceps) and one Magellanic Penguin (Spheniscus magellanicus) killed during 394 hauls on 124 trips in the five fishing areas.
Coastal trawl fisheries appear to have a small impact on Patagonian seabirds in terms of incidental mortality, but might have a significant effect through the provision of fishing waste, especially for Kelp Gull and Black-browed Albatross populations.

La Gaviota Cocinera Larus dominicanus y el Albatros Ceja Negra Diomedea melanophris fueron las aves marinas m~is importantes en las flotas costeras, tanto en frecuencia de ocurrencia como en abundancia, seguidas por el Petrel Neg...
Spearfishing was becoming an increasingly important economic activity in the Caribbean as a result of socioeconomic factors related to underemployment and the low capital outlay for equipment. For a year (2011) we surveyed spearfishing in 23 Jamaican beaches. Spearfishing has expanded from approximately 1% of fishers in 1991 to about 10% in 2011. The fishery is larger than expected and probably produced 4 000tons per year. Though reef fishes dominated catches, other resources such as lobsters, conch and octopus were regularly taken. Many small juvenile fishes were observed in catches well below their adult or optimum sizes. A total of 58% of spear-fishers reported they would have significant difficulty finding alternative employment if spearfishing was banned. Spearfishers reported exploiting the entire island shelf and also nearly all the offshore banks, especially Pedro Bank. Night spearfishing was common and targeted sleeping reef fishes. The activity is banned and should be enforced. Our recommendations include: register all spearfishers, actively manage spearfishing, a partial ban for part of the year and a ban on using scuba and hookah gear for spearfishing. Rev. Biol.
