Assessment Of Structure Of Largemouth Bass Stocks By Sequential Sampling
We examined the accuracy and application of sequential sampling to determine structure of fish stocks, using electrofishing data for largemouth bass (Micropterus salmoides) as an example. Structure of the stock was categorized with the index of Proportional Stock Density (PSD), which is the percentage of quality-size fish in the stock. Minimum stock and quality sizes for largemouth bass were defined as 20 and 30 cm, respectively. Sequential sampling is based on data evaluation during collection. An average reduction in sample size of 42% is realized when populations are sampled...
