Discussion
- Preferred temperature 12.1 C, so body temperature 17 C is assumed
- Males are assumed to differ from females by {p_Am} only
- Cole2010 gives an estimated fecundity of 7.2e6 to 9.7e6 eggs for FL 93.6 cm, but 5.7e5 seems to be maximum for optimized kappa, given the other best-fitting parameters.Notice that 8e6 eggs weigh 51 kg, while a fish of FL 93.6 weighs 23 kg. That seems a lot of eggs, even when accounting for partial dehydration
- The large value for [p_M] that was found, probably relates to the cost of enthermy
Facts
- Keeps its body core approximately 5 C warmer than its environment (Ref: Wiki)
- weight-length Ww in g = 0.02239*(TL in cm)^3.02 (Ref: fishbase)
