Evaluating genomic selection, genetic compatibility, and reproductive success in hatchery-origin coho salmon (Oncorhynchus kisutch)

Frontiers in Ecology and Evolution
Genetic compatibility arises from the combined effects of assortative (matching) and disassortative (mismatching) alleles in mated pairs and may have undeveloped utility in conservation breeding programs.

Expert‐Based Prioritization of Control Measures for Salmonid Rickettsial Septicemia in Chilean Salmon Aquaculture

Journal of Fish Diseases, EarlyView.
ABSTRACT Piscirickettsiosis (SRS) remains the main infectious disease affecting salmon aquaculture in Chile. This study evaluated expert perceptions of the effectiveness of SRS control measures and the level of agreement among industry professionals.

Assessment of Salinity Tolerance in Lepeophtheirus salmonis Following Five Generations of Freshwater Treatment Selection

Journal of Fish Diseases, EarlyView.
ABSTRACT Non‐medicinal approaches for controlling sea lice (Lepeophtheirus salmonis) infestations, such as freshwater (FW) treatments, have been increasingly implemented to support more sustainable parasite control in aquaculture. This study evaluated the efficacy of FW treatment against sea lice under controlled experimental conditions and assessed ...

Development of a Multiplex Polymerase Chain Reaction Assay for Differentiating Three Lactococcus Species Associated With Piscine Lactococcosis

Journal of Fish Diseases, EarlyView.
ABSTRACT Piscine lactococcosis is an important bacterial disease of farmed fish. The causative agents, Lactococcus garvieae, Lactococcus petauri and Lactococcus formosensis, are closely related, which complicates species‐level identification. We developed a conventional multiplex PCR assay targeting species‐specific genes identified by comparative ...

Divergence of sexual size dimorphism between wild and hatchery chum salmon under intensive Japanese hatchery programs [PDF]

Artificial propagation weakens sexual selection by reducing male-male competition and female choice, which favor larger males in natural reproduction. If homing ability and sexual selection were strong, wild-origin salmon would exhibit more pronounced ...

Similarities Between the Lipid Profiles of Skin and Liver of European Sea Bass (Dicentrarchus labrax) Fed Diets With Different Lipid Content

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT The fatty acid composition of fish is influenced by species, age, diet, and tissues, which respond differently to dietary lipids. This study examined how two commercial diets with contrasting polyunsaturated fatty acid (PUFA) profiles, affecting eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), alter the fatty acid composition in ...

Identifying thermally tolerant bull kelp (Nereocystis luetkeana) source populations for restoration under climate change

Journal of Phycology, EarlyView.
Abstract Kelp forests are declining in many parts of the world due to climate change and other stressors. Restoration is one solution to return kelp forests to places where they have been lost, yet continually warming oceans may necessitate the identification of thermally tolerant strains to facilitate the long‐term success of kelp restoration.

Diel release timing is a critical determinant of reef fish survival in Post‐larval Capture, Culture, and Release

Restoration Ecology, EarlyView.
Abstract Introduction Predation is a dominant force shaping survival of coral reef fishes. Synchronous, nocturnal settlement during low‐light, new moon periods may have developed as an adaptive response to intense predation during settlement. Post‐larval Capture, Culture, and Release (PCCR), where juvenile fishes are released directly to the reef ...
