- •
Time series of D. gigas and D. gahi catches are not related to thermal anomalies.
- •
Time series of D. gigas and D. gahi catches show that the changes in abundance are related to first order dynamics. This suggests that denso-dependent processes affect populations of these squids. This can be modeled as a function of density observed in previous years.
- •
Population dynamics of squids are related to their life-history strategies.
