چکیده انگلیسی
In this paper, life history characteristics of tropical flatfishes occurring at the fringing reefs of Curaçao to a depth of 20â¯m were studied. In total four flatfish species were caught, three common Bothidae species: the eyed flounder Bothus ocellatus, the mottled or maculated flounder B. maculiferus and the peacock flounder B. lunatus, and -in small numbers- the channel flounder Syacium micrurum. B. ocellatus and S. micrurum only occurred in sandy moats on the shallow reef terrace and fore reef and between coral patches on the terrace and fore reef slope. The other species could also be found on coral patches. The depth distribution of the various species overlapped: all species were caught over a depth range from a few meters up to 20â¯m. All Bothus species were carnivores, preying on a variety of mobile benthic animals such as fishes and crustaceans. Reproduction seemed to occur year round in all three Bothus species. Growth between the species varied considerably with a maximum age found in B. maculiferus and B. lunatus of a little over 1â¯year, and in B. ocellatus of about 2â¯years. Growth was lowest in B. ocellatus and highest in B. lunatus: after one year B. ocellatus was about 10â¯cm in size, B. maculiferus 25â¯cm and B. lunatus about 35â¯cm. After correction for differences in water temperature, the Bothus species showed a similar variability and range in growth rate as some temperate and subtropical flatfish species. These observations do not fit the hypothesis postulated by Pauly (1994) of an increasing importance of food-limitation in juvenile flatfish with decreasing latitude, despite the low densities and biomass of benthic in- and epifauna in the soft sediments in mangroves, seagrass beds and the reefs of Curaçao.
