The aspect ratio of the caudal fin of 63 fish species was measured. Swimming speeds for these species, representing 129 cases, were obtained from the literature for various fish sizes and speeds, i.e. "minimum speed" for sustained swimming and "maximum speed" (+ "burst" speed). Results show a...

An attempt to fit the von Bertalanffy growth equation to three species of deep sea snappers using the ELEFAN method was unsuccessful, mainly because the fish are slow-growing, long lived species. Problems were also encountered in estimating asymptotic length and Z/K using a Wetherall plot....

Catch assessment estimates for the motorized and non-motorized canoes at Boa-Manga (Cameroon) were found to be 5.13 and 2.70 t/year, respectively, leading to an estimated lower limit for the production of the Ocean division (100 km coastline) of 1190 t/year. The net economic benefit for the...
