We explore the properties of a simple model to determine the optimal time to harvest a hypothetical squid population. Optimality criteria involve both commercial and management objectives; to maximize profitability and ensure the survival of a minimum spawning stock. Optimal harvest times depend on natural mortality and growth rates. This relationship is modified by squid price when the commercial objective is to maximize catch value. We also consider the risk associated with mistiming of fishing events. Data from a commercially exploited squid stock, Falkland Islands Loligo gahi, suggest that early harvesting is often appropriate for this species.
