Seasonality and Chaos in a Plankton Fish Model

Theoretical Population Biology, 1993
The dynamics of a plankton-fish model comprising phosphorus, algae, zooplankton and young fish are analyzed for different values of average light intensity, phosphorus concentration in the inflow, and adult fish biomass. Light intensity and water temperature are periodically varied during the year, while the other parameters are fixed at realistic ...

The Impact of Transferable Fishing Quotas on Cost, Price, and Season Length

Marine Resource Economics, 2021
Individual fishing quotas give fishers incentives to reduce costs (or increase productivity), lengthen the harvest season and increase price by improving catch quality. To what extent each of these three effects will be present when the management system

Fishing Behavior and the Length of the Fishing Season

Marine Resource Economics, 1998
The basic hypothesis of this paper is that the amount of fishing that a fish harvester undertakes during a year is not determined entirely by circumstances which are exogenous to the fisher, such as weather conditions and resource availability, but is also partially a matter of individual choice.

Seasonal variation and the immune response: A fish perspective

Fish & Shellfish Immunology, 2007
The environment in which an animal lives affects the physiology and psychology of that animal. The greater the distance from the equator the more profound this influence becomes, as the environment becomes more variable over the years. Temperature, photoperiod, precipitation and other environmental conditions, which are directly or indirectly ...
