Maternal Output in Polar Fish Reproduction
43
FEe is fecundity (i.e. the total number of eggs to be spawned per
individual fish). Thus, MO is the total volume of eggs expressed in mm 3 .
Table 1. Reproductive parameters of 59 marine fish species. Species are grouped according
to their mode of oviposition, i.e. pelagic and demersal, and zoogeography, i.e. boreal and
polar (Arctic and Antarctic combined). BL = body length (mm); ED = egg diameter (mm);
EV = egg volume (mm\ FEC = fecundity (no. ind- I ); MO = maternal output (mm 3 ind- I );
na = data not available. References to the reproductive parameters are in brackets following
