The Forgotten Requirement for Age Validation in Fisheries Biology

Abstract: A survey of 500 studies published between 1907 and 1980 that included estimates of fish age indicated that only 65% mentioned age validation or attempted to validate the ageing technique In less than 3% was the technique validated for all age classes Among the 35% that did not consider age validation, many did not consider the possibility that ages may be incorrect Among 75 additional publications published in primary journals between 1965 and 1980 that assessed stock dynamics and used fish ages, only 40% mentioned or attempted age validation, and none successfully validated all age groups used in the analysis Many investigators continue to neglect the critical study of age validation despite the clear direction of the early work on age determination We show that estimated ages greater than the maximum validated age must not be considered accurate Use of inaccurate ages has caused serious errors in the management and understanding of fish populations Only by mark-recapture studies or use o

Gene Nomenclature for Protein-Coding Loci in Fish

Abstract: The Fish Genetics Section of the American Fisheries Society established its Nomenclature Committee to develop and promote standardized genetic nomenclatures. Here, following public comments on previously published draft guidelines, we present the committee's revised version of a nomenclature for protein-coding loci in fish. This nomenclature closely parallels the one used for human genetics, but improves on it in several respects. The fish system (1) includes standardized abbreviations for commonly analyzed proteins, and provides formal symbols for gene loci encoding these proteins; (2) specifies typographic conventions for distinguishing between genes and proteins and for identifying alleles; (3) provides for multilocus isozyme systems, isoloci, regulatory loci, and pseudogenes; (4) allows important basic information (such as subcellular distributions of gene products, active substrate isomers, recent gene duplicates, and orthologous relationships among loci) to be specified in gene symbols via ...

Predator-Prey Interaction between Largemouth Bass and Bluegills as Influenced by Simulated, Submersed Vegetation

Abstract: Data from the literature suggest that predatory success declines as habitat complexity increases. To explain this phenomenon, we studied the predator-prey interaction between largemouth bass Micropterus salmoides and bluegills Lepomis macrochirus in four laboratory pools (2.4–3.0 m diameter, 0.7 m deep), each with a different density (0, 50, 250, 1,000 stems/m2) of artificial plant stems. Behavior was quantified for both predator and prey during largemouth bass feeding bouts lasting 60 minutes. Predation success (number of captures) by largemouth bass was similar at 0 and 50 stems/m2, then declined to near zero at 250 and 1,000 stems/m2. As stem density increased, predator activity declined due to a decrease in behaviors associated with visual contact with prey. Reduced predation success by largemouth bass in habitats of increased complexity apparently is related to increases in visual barriers provided by plant stems as well as to adaptive changes in bluegill behavior.

Primary and Secondary Effects of Stress in Fish: Some New Data with a General Review

Abstract: Handling in fish induces perturbations of various biological parameters which have been investigated or reviewed in an attempt to analyse and quantify the resulting stress. Endocrine changes, being early consequences of stress, are referred to as primary effects. Original data obtained on coho (Oncorhynchus kisutch), sockeye (O. nerka), and chinook (O. tshawytscha) salmon show that all types of stress result in an increase in circulating catecholamines, mainly adrenaline. There is no quantitative difference in response intensity between the species studied but large individual variations exist. In mature male coho salmon, struggling and hypoxia also resulted in an increase of plasmatic corticosteroids. Secondary effects occur as a result of these endocrine changes. Metabolic disturbances include a pronounced increase in blood glucose, and either a decrease or an increase of plasmatic free fatty acid (FFA) according to the species. These metabolic disturbances brought about by stress of short dura...
