Discussion
- Metamorphosis is assumed to not affect morphology, not metabolism
- Males are assumed to have the same parameters as females
- weight 0 is given to age at birth, length at birth, ultimate physical length.Age at birth is unknown and we do not have yet a good guess. shape changes so we think a different shape coeff in the early stages would be different.Wwi corresponds to heaviest individual measured by Lago2016, and the Li was from the literature-as we have weight-length we prioritize a good fit for Wwi over that of Li. The Ni data is an assumption from Hosi1982, more realistic implementation of modelling original data should be implemented in a future version. The egg dry weight is an actual measurment and so is given more weight.
- v, kap and p_M are given more weight to account for the paucity of information on this species life-cycle.
- we accept a loss of fit in the initial part of the t-L curves which we attribute to changes in shape
Facts
- Production of mature ova is continuous and oviposition takes place roughly every 30 days. (Ref: Hosi1982)
- Feeding starts at stage Calyptopsis I (Ref: Hosi1982)
- Intermoult time is temperature dependant. (Ref: Hosi1982)
