Length-weight relationship of six pelagic copepods from Bahia de La Paz, Mexico
Sergio Hernández Trujillo, Gabriela María Esqueda Escárcega y Sonia Futema Jiménez
The relationship between dry weight (DW) and prosome length (PL) were assessed for seven species of pelagic copepods from Bahia de La Paz: Acartia clausi, A. lilljeborgii, Centropages furcatus, Labidocera johnsoni, Temora discaudata, and Undinula vulgaris. The species of higher length and dry weight was U. vulgaris (1. 99±0. 12 mm, 218. 54±33. 04 !g, respectively) and the lowest was A. clausi (0. 82±0. 03 mm, 0. 044±0. 01 !g, respectively). The dry weight-prosome length relationships were significant for three copepod species: A. clausi (logDW=1.06LogPL- 1.49, p< 0.05), L. johnsoni (logDW= 0.56LogPL+0.26, p<0.05), and T. discaudata (logDW= 1.175LogPL-1.61, p<0.05). The effect of food conditions on the relationship was examined using the condition factor. Next step is adjusted mean weight and length along the year to establish a comprehensive regression equation by examining samples collected in as many months as possible.
