What is proportional stock density?
Proportional Stock Density (PSD) is a measure of species size structure. The metric is a ratio (expressed as percentage) between the number of quality-sized individuals or larger individuals and stock-sized individuals. Stock and quality size designations vary by species.
What is PSD in fisheries?
Proportional Stock Density (PSD) Method. A simple method of assessing the current status of a pond fishery is the use of proportional stock density (PSD). The PSD method is applicable to ponds dominated by a largemouth bass and bluegill combination.
What is proportional size distribution?
Proportional size distribution (PSD) indices, which formerly were referred to separately as proportional and relative stock densities, are convenient measures for numerically summarizing fish length frequency data and facilitating comparisons of size structure among fish populations (Willis et al.
How do you calculate fish population?
The most basic probability sampling procedure used in fish population sampling is simple random sampling, in which a predetermined number of sampling sites is selected from all possible sampling sites such that every potential site has an equal chance of being selected (Hansen et al.
How do you count fish in pond?
You divide the number of fish you found by the area of water you counted and get the density of fish in the reservoir. Then you multiply density by the area of the reservoir and you can have a rough idea about total quantity of fish in a reservoir. You will have to develop a sampling design to estimate fish abundances.
What is fish population dynamics?
Fish population dynamics is the study of change in a fish population over time. Fundamentally, a population size after some time interval equates to the population size before that interval plus births (i.e., recruitment) and immigration and minus mortality and emigration.
Why do fish populations vary?
Fish populations vary because of density-dependent and -independent processes that determine recruitment, growth, and natural mortality, and in response to fishing.

Common Fish Populations
All fish have specific water temperature tolerances. Warm-water fish, like largemouth bass and sunfish, prefer water temperatures above 80°F in the summer while cold-water fish, like trout, cannot survive if the summer water temperature exceeds 75°F for a prolonged time.
Measuring Your Fish Population
Approximately 15 percent of pond owners surveyed indicated that they had little or no knowledge of the current status of their pond fishery. The most accurate method for determining the fish population is to hire a professional fisheries biologist to sample the pond using a boat electrofishing unit (Figure 2).
Proportional Stock Density (PSD) Method
A simple method of assessing the current status of a pond fishery is the use of proportional stock density (PSD). The PSD method is applicable to ponds dominated by a largemouth bass and bluegill combination. The method is less accurate for other combinations of bass and/or sunfish.
A Bass Crowded Pond
The example pond from Table 1, when plotted on Figure 3, is considered a "bass-crowded" pond characterized by numerous small bass and few but large bluegill. This condition occurs most frequently in ponds that are not consistently fished. If bass are not routinely harvested, they may overcrowd the pond and reduce the bluegill population.
A Bluegill-Crowded Pond
A bluegill-crowded pond has many small bluegill and just a few large bass. This population structure often occurs in ponds that are regularly fished. Anglers tend to overharvest bass and underharvest bluegill. As a result, large bass are continually removed, allowing more bluegill to survive.
Angling Guidelines
The harvest guidelines presented above are useful to change a pond fish population, but what should be done once the desired fish population is achieved? Fish management is a continuous process that is necessary even to maintain a stable fish population. Here are some guidelines for anglers to keep the pond bass and bluegill population stable:
Miscellaneous Fish Management Issues
Creating optimum fish habitat is easiest done during the construction of the pond. Slightly undercut banks and rock ledges can be created during construction to provide great habitat for both bass and bluegill. Large trees cleared during construction can be placed on the bottom of the pond to provide additional habitat.
