Fecundity and reproductive habits in Patagonotothen tessellata (Richardson, 1845) from the Beagle Channel, Argentina
Population fecundity and reproductive habits in Patagonotothen tessellata were established for each reproductive period during 1988 and 1989. Fecundity/total length and fecundity/total weight relationships were analysed through regression models. Fecundity was positively correlated with fish length...

Mean fecundity was 25932 eggs (range 7634–62033). The regressions for each reproductive period are similar, suggesting that the amount of energy allocated to reproduction does not vary between spawning periods.
