Document Summary
Case 12: slot length for lmb in a small impoundment: slot sizes are used to restructure high-density, slow growing lmb in a small impoundment. Factors to consider: recruitment (to population, fishery, or gear, growth (incremental increase, length and/or weight, from one period of time to another, mortality (lack of survival from one year to the next) Also consider: desirable size to anglers (age of recruitment to fishery, psd categories, maximum sustainable yield, current or predicted harvest rates. Condition factors: relative weight (wr) weight/length relationship, 100 is a good condition (standard) Relative abundance may not include the younger portion of the population. Length or age on x-axis, and frequency on y-axis. What proportion of fish in a population (stock) are of a desirable size to anglers. Categories are stock, quality, preferred, memorable, or trophy. Smaller fish may be completely absent from a psd graph. Brian started that year, water level was low .
