France, R., Holmes, J., & Lynch, A. (1991). Use of size-frequency data to estimate the age composition of crayfish populations (Vol. 48).
Zusammenfassung: Age-classes in crayfish populations can be determined from size-frequency data provided 4 tents are adhered to only crayfish collected from areas of rock substrate are used; trapping are excluded; species do not have longevities exceeding about 4 yr; and most importantly, sample sizes are greater than about 200. Studies that have failed to follow these guidelines have met with limited success in dissecting mixed frequency distributions. Further, 3 validation procedures must be undertaken: temporal replication within molting events to measure the precision of both data collection and size-frequency analysis; corroboration with known-age crayfish from either field recaptures or laboratory molt increments; and concordance with independent analysis of the mean size at onset of sexual maturity. When these checks support the size-frequency results, population age composition and analyses of rates of growth or mortality can be considered reliable.

Zusammenfassung: A classification system for whitefish (Coregonus lavaretus L. s.l.) stocks was developed. The classification program is based on frequency distributions of gillrakers and length distributions in different age-groups. The system is based on time sharing, interactive use of a UNIVAC-1108 computer with a terminal.

Boutillier, J., Noakes, D., Heritage, D., & Fulton, J. (1988). Use of multiattribute utility theory for designing invertebrate fisheries sampling programs (Vol. 8).
Zusammenfassung: Multiattribute utility theory (MAUT) and integer programming are employed to examine optimal sampling strategies for commercial invertebrate fisheries in British Columbia, Canada. Attributes considered in the study take into account various biological, economic, social, and political aspects of the fisheries. Twenty-six fishery managers, biologists, and researches from the Department of Fisheries and Oceans participated in ranking and assigning weights to each of the attributes to provide overall utility scores. Integer programming was then employed to generate optimal sampling strategies subject to various cost, personnel, are, and fishery constraints. The results clearly demonstrate the potential usefulness of MAUT analysis for developing strategies to monitor commercial invertebrate fisheries.
