HOT and Hawaii's Fisheries Landings: Complementary or Independent Time-Series?

Jefrrey J. Polovina and Donald R. Kobayashi

Abstract

The Hawaii Ocean Time-Series (HOT) is a time-series of oceanographic point estimates at a fixed site off Oahu. The population abundance of coastal pelagic and demersal fishes are determined through an integration of physical and biological factors over temporal and spatial dimentions. Further, variation in fishery landings can be the result of not only changes in population size but also changes in catchability, targeting, and reporting. Is it likely to expect a relationship between the two time-series? What species would be most likely to show a relationship? What do the data show?
