Abstract
Measurements of total length (TL) and total weight (Wt) of the coney,Epinephelus fulvus (n = 418), and the red hind, Epinephelus guttatus (n = 512); and, measurements of fork length (FL) and total weight for the queen snapper, Etelis oculatus (n = 173), were collected in Nevis from March to May, 1995. The data were used to calculate length/weight relationships (in millimetres and grammes) for the three species. These relationships are presented: for E.fulvus weight (Wt) is equal to 3.394 x 10-5 x TL3 274; for E. guttatus it is equal to 1.2 18 x 10-6 x TL3.397; and for E. oculatus to 4.754 x 10-5 x FL2.801. These results, on comparison to those obtained from previous studies, may be interpreted as suggesting that the stocks fished in Barbados, St. Lucia, and Nevis could be from the same biological population. While these results may be considered just preliminary, they are among the first significant scientific results to be produced from data obtained by the island’s fisheries data collection system
