Fish availability is the proportion of the population living in an area where it can be taken by the fishery during a given fishing season.

In contrast to artificially bred fish supplied year-round, the catch of wild fish occurs at certain times, depends on the biological cycle, which each fish has its own. During these seasons the main production of seafood for the food industry takes place. The availability of raw materials and their value for the whole year depends on how the season goes, how much fish is caught.
