| Abstract |
Aspects of the population and reproductive biology of the mysid Mesopodopsis slabberi were studied in the western Mediterranean (Encanyissada coastal lagoon, Ebro Delta, Spain). Misids were sampling at monthly intervals from August 1993 to June 1995. In December 1994 and February 1995 any individuals were found. The relationship between carapace length (Lc) and total length (Lt) was isometric: logLt = 1.0612logLc + 0.9411 (n = 178, r = 0.9411). The size of mature males and females was at a maximum in the winter, and a minimum in the summer. The longevity of individuals changed throughout the year; those with the longest life expectancy were members of the overwintering generation. Brooding females were recorded throughout the year, except in December 1993 and April 1994; they were most numerous in spring and autumn. The number of embryos or larvae (N) carried by females was related to the size of the females (range: 1-22, mean value: 4.8): logN = 1.8705logLc-0.0985 (n = 361, r = 0.4097, P<0.01). The size of the eggs (maximum diameter, Le) was related to the size of the females (range: 0.35-0.6 mm in total length): logLe = 0.3404logLc-0.4820 (n = 277, r = 0.5420, P<0.01). |
