Quarterly Fishery Surveys - Salton Sea [ds428]

After each quarter's sampling is completed a draft report is prepared, summarizing the numbers and species of fish netted, and calculating the overall and species-based catch-per-unit-effort (CPUE). The primary focus of sampling is to establish presence/absence of species, and populations trends. This report will also offer qualitative comments on the condition and breeding status of each species. After annual repetitions of seasonal sampling, enough data will be collected to allow statistical tests for population trends, significant differences in numbers, seasonality, and site use, by and among the four species of sportfish. These data and analyses will be informative to the management of the fisheries, and the efforts to restore the Salton Sea.
