Abstract
Aspects of the population and reproductive biologyof the mysid Mesopodopsis slabberi were studiedin the western Mediterranean (Encanyissada coastallagoon, Ebre delta, Spain). Misids were sampling atmonthly intervals from August 1993 to June 1995. InDecember 1994 and February 1995 any individuals werefound. The relationship between carapace length (Lc)and total length (Lt) was isometric:logLt = 1.0612logLc + 0.9411 (n = 178,r = 0.9411). Thesize of mature males and females was at a maximum inthe winter, and a minimum in the summer. The longevityof individuals changed throughout the year; those withthe longest life expectancy were members of theoverwintering generation. Brooding females wererecorded throughout the year, except in December 1993and April 1994; they were most numerous in spring andautumn. The number of embryos or larvae (N) carried byfemales 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). Thesize of the eggs(maximum diameter, Le) was related to the size of thefemales (range: 0.35–0.6 mm in total length):logLe = 0.3404logLc−0.4820 (n = 277, r = 0.5420, P < 0.01).
