| Abstract | In total, 109 fish species (24,996 individuals)were sampled around Guadeloupe andMartinique Islands from October 2021 to September 2022 to estimate the morphometric relationships between total length and weight (LengthWeight Relationship: LWR) of each fish species according to potential spatial, temporal and sex differences. Of these species, this is the first time that the LWR was estimated in the Atlantic Ocean for 16 species. There is a significant relationship between length and weight for all tested species. For 83 tested species, the sex effect on the LWR showed significant sexual dimorphism for 24 species. Additionally, a link between the temporal effect and the reproduction period was tested for 68 species, of which 35 presented significant differences relative to the annual quarter of sampling. Finally, the geographical effect (i.e., the difference between samples from around Guadeloupe Island and those fromMartinique Island) was significant for 60 species. This island effect was significant for 25 species. |
