Discussion
- Weight at birth is guessed from Sterechinus which has Wd0 of 0.5 mug
- In view of low somatic maintenance, pseudodata k_J = 0.002 1/d is replaced by pseudodata k = 0.3
- mod_1: GSI because found information for the species (it was a guess in the original mod)
- mod_1: ldl added data from ; average annual water temperature 11C, ranges from 9.5°C (49°F) in April up to 12.9°C (55.1°F) in September, https://www.watertemperature.org/Salt-Point-State-Park-UnitedStates-Beach.html
- mod_1: LDw added data to model_1
- mod_1: WwJO added data to model_1
- mod_1: LWw added data to model_1; LWw, LDw, WwJO, and LR were measured for the same individuals (not all ind have all measurements)
- mod_1: L-R data assumes yearly spawning, so the mean accumulation time is 365/2 d
