Willson February 1997 Author MARY F. WILLSON is a research ecologist, Forestry Sciences Laboratory, 2770 Sherwood Lane, Juneau, AK 98801. Abstract Willson, Mary F. 1997. Variation in salmonid life histories: patterns and perspectives. Res. Pap. PNW-RP-498. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 50 p. Salmonid fishes differ in degree of anadromy, age of maturation, frequency of repro- duction, body size and fecundity, sexual dimorphism, breeding season, morphology, and, to a lesser degree, parental care. Patterns of variation and their possible signif- icance for ecology and evolution and for resource management are the focus of this review. Keywords: Salmon, char, Oncorhynchus, Salmo, Salvelinus, life history, sexual dimor- phism, age of maturation, semelparity, anadromy, phenology, phenotypic variation, parental care, speciation. Summary Salmonid fishes differ in degree of anadromy, age of maturation, frequency of reproduction, body size and fecundity, sexual dimorphism, breeding season, morphology, and to a lesser degree, parental care. The advantages of large body size in reproductive competition probably favored the evolution of ocean foraging, and the advantages of safe breeding sites probably favored freshwater spawning. Both long-distance migrations and reproductive competition may have favored the evolution of semelparity. Reproductive competition has favored the evolution of secondary sexual characters, alternative mating tactics, and probably nest-defense behavior. Salmonids provide good examples of character divergence in response to ecological release and of parallel evolution. The great phenotypic plasticity of these fishes may facilitate speciation.

  • Acquisition of Potential for Sperm Motility in Rainbow Trout and Chum Salmon
    J. exp. Biol. 126, 89-96 (1986) 89 Printed in Great Britain © The Company of Biologists Limited 1986 ACQUISITION OF POTENTIAL FOR SPERM MOTILITY IN RAINBOW TROUT AND CHUM SALMON BY SACHIKO MORISAWA Biological Laboratory, St Marianna University, School of Medicine, 2095 Sugao, Miyamae-ku, Kawasaki 213, Japan AND MASAAKI MORISAWA Laboratory of Physiology, Ocean Research Institute, University of Tokyo, 1-15-1 Minamidai, Nakano-ku, Tokyo 164, Japan Accepted 17 July 1986 SUMMARY The male reproductive organ of rainbow trout and chum salmon consists of a pair of testes and sperm ducts. Spermatozoa in the distal portion of the sperm ducts exhibit full motility in the K+-free medium. However, spermatozoa from the testis were almost immotile in this medium. This suggests that the spermatozoa acquire a capacity for movement during their passage from the testis along the sperm duct. In chum salmon migrating into a bay, the sperm duct was almost empty. However, after the fish have travelled upstream for 1 km to their spawning ground in the river, the spermatozoa have left the testis, moved into the sperm duct and are capable of becoming motile. Thus it is probable that the process of acquiring the ability to move occurs within a relatively short period in this simple reproductive organ. Additionally, testicular spermatozoa demembranated with Triton X-100 exhibited motility, although the motility was less than that of demembranated spermatozoa from the sperm duct, suggesting that the acquisition of motility may correspond with the development of some function of the plasma membrane. INTRODUCTION Since Tournade (1913) demonstrated that mammalian spermatozoa acquire mo- tility during transit through the epididymis from the caput to the cauda after spermiation, much effort has been devoted to understanding the mechanism of this phenomenon (Hoskins, Brandt & Acott, 1978).

It is classiied as endangered (EN) by the IUCN due to its very low abundance and continual decline. Historically, the natural distribution range of the Danube salmon included drainages in Austria, Bosnia-Herzegovina, Montenegro, north-western Croatia, Czech Republic, Germany, Poland, Romania, Serbia, Slovakia, Slovenia and western Ukraine. Currently, Danube salmon populations are fragmented within the Danube drainage, with many being supported by artiicial reproduction and stocking programs.

  • ICES Marine Science Symposia
    II. Fish ICES mar. Sei. Symp., 194: 31-55. 1992 Pacific salmon in Atlantic waters Yves Harache Harache, Y. 1992. Pacific salmon in Atlantic waters. - ICES mar. Sei. Symp., 194:31-55. A century of Pacific salmon introductions to Atlantic waters is summarized. Move­ ments of fish were initiated in the last century, and in many countries large quantities of eggs have been introduced into rivers on both sides of the North Atlantic Ocean. The motivations for such programmes, the techniques used, and the results arc analysed for most of the documented attempts to introduce these species in the Atlantic area, with special attention being given to recent introductions (since 1950). Programmes for the introduction of Pink salmon (Oncorhynchus gorbuscha) in Newfoundland (Canada) and the Kola Peninsula (USSR) are reviewed in detail, and the use of coho salmon (Oncorhynchus kisutch) for ranching (New Hampshire, USA) and farming (Europe) is described. Pacific salmon released in Atlantic oceanic areas have shown in most cases an aptitude for survival, growth, homing, and spawning, even in areas where environmental characteristics are substantially different from their home waters. Survival rates are generally lower than in the original range and straying relatively important. However, in spite of significant returns, all attempts to establish reproducing sea-going populations have failed in the northern hemisphere. Although not developing rapidly, the use of coho salmon for aquaculture in Europe has an interesting potential. The possible causes of success or failure of the different attempts are discussed; they include an analysis of the adaptive mechanisms of populations which exist in their original habitat, and the influence of the ecological characteristics of the receiving country on the biology of the species.
