总的来说,从2021年10月至2022年9月,在瓜德罗普岛和马提尼克岛附近采样了109种鱼类(24,996个个体),以根据潜在的空间估计每种鱼类的总长度和重量之间的形态关系(长度重量关系:LWR)。时间和性别差异。在这些物种中,这是首次在大西洋中估计LWR为16种。所有测试物种的长度和重量之间都存在显着关系。对于83个测试物种,对LWR的性别效应在24个物种中表现出明显的性二态性。此外,对68个物种的时间效应和繁殖期之间的联系进行了测试,其中35个与抽样的年度季度有显著差异。最后,地理效应(即,瓜德罗普岛周围的样本与马提尼克岛的样本之间的差异)对于60种物种而言是显着的。这种岛屿效应对25个物种来说是显著的。
In total, 109 fish species (24,996 individuals) were sampled around Guadeloupe and Martinique Islands from October 2021 to September 2022 to estimate the morphometric relationships between total length and weight (Length Weight 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 from Martinique Island) was significant for 60 species. This island effect was significant for 25 species.
