The effects of environmental stress on the physiology of growth in rainbow trout, Salmo gairderi Richardson [PDF]
, 1988 There is little doubt that both mammalian and teleost growth hormones can accelerate growth and increase food conversion efficiency in all commonly-reared species of salmonid fish.

Fish and Fisheries, Volume 27, Issue 3, Page 431-450, May 2026.ABSTRACT Hatcheries and stocking programmes have long been a cornerstone of fisheries management, seen as tools for fisheries enhancement and/or conservation of threatened populations. Their use draws controversy, however, from a growing body of research over the last 50 years suggesting that stocking can have negative consequences for wild stocks, and

Journal of Integrative Plant Biology, Volume 68, Issue 4, Page 985-1012, April 2026.For a century, Vitamin E has been studied for its health benefits. This review traces its journey from basic biological discovery, and the recent identification of its link to chlorophyll degradation, to the modern era of sustainable microbial manufacturing, highlighting the innovative technologies that define its future production.

Electrical phase angle as a new method to measure fish condition [PDF]
, 2009 In this study, phase angle (the ratio of resistance and reactance of tissue to applied electrical current) is presented as a possible new method to measure fish condition.

The Genetic Basis of Color Polymorphism in the Orb‐Web Spider Gasteracantha cancriformis
Ecology and Evolution, Volume 16, Issue 3, March 2026.This study investigates the genetic basis of coloration in the polymorphic spider Gasteracantha cancriformis using RNA‐seq data from different female color morphs. We assembled a reference transcriptome and identified differentially expressed genes associated with known pigmentation pathways, including carotenoids, melanin, ommochromes, and pteridines.

Heterozygosity and morphological variability of chum salmon (Oncorhynchus keta) in southern British Columbia [PDF]
Heredity, 1985 We compared variability in two meristic and six morphometric characters with heterozygosity within and among 27 populations of chum salmon (Oncorhynchus keta) in southern British Columbia. Among individuals, there was no relationship between levels of heterozygosity at 10 electrophoretic loci and degree of meristic or morphometric variation.

Range‐wide life history diversity and climate exposure in adult Chinook salmon
Ecosphere, Volume 17, Issue 3, March 2026.Abstract Climate change is threatening ecologically and culturally important species. For species with broad ranges and complex life cycles, such as migratory Pacific salmon (Oncorhynchus spp.), climate exposure may vary across space and diverse life history strategies.

Ecotoxicity Thresholds for Ametryn, Diuron, Hexazinone and Simazine in Fresh and Marine Waters [PDF]
, 2018 Triazine and urea herbicides are two groups of photosystem II inhibiting herbicides frequently detected in surface, ground and marine waters. Yet, there are few water quality guidelines for herbicides. Ecotoxicity thresholds (ETs) for ametryn, hexazinone

Genetic structure of chum salmon Oncorhynchus keta river populations.
NIPPON SUISAN GAKKAISHI, 1983 Chum salmon populations which distributed extensively from North America via the U. S. S. R. to Japan were investigated. Several regional populations consisting of adjacent river populations were identified from the gene frequency data. It is presumed that the accumulation of the genetic intermingling for generations lead to genetic similarity among ...
