Table 2.
Carapace length, body weight, body indices, gonad maturation stage in females and lipid content in pooled samples from relevant tissues in Nephrops collected in the Clyde Sea area at different times of the year: Winter-December; Spring-April; Summer-July and Autumn-September. Values represent mean ± SEM. Number of replicates in body indices is n = 20 and lipid composition is n = 3. Different letters indicate values that are significantly different according to season (p < 0.05).
