Intersex Gonad Differentiation in Cultured Russian (Acipenser gueldenstaedtii) and Siberian (Acipenser baerii) Sturgeon1 [PDF]

open access: yesBiology of Reproduction, 2014
Among sturgeons, the occurrence of individuals with gonads containing both testis and ovary components is considered pathological, and such fish are described as intersex individuals or intersexes. Intersexes are observed in both wild and cultured populations of sturgeon, usually at low frequencies.

Immersion challenge of three salmonid species (family Salmonidae) with three multilocus sequence typing variants of Flavobacterium psychrophilum provides evidence of differential host specificity

open access: yesJournal of Fish Diseases, EarlyView., 2023
Abstract Bacterial coldwater disease (BCWD), caused by Flavobacterium psychrophilum, results in significant losses among multiple salmonid (family Salmonidae) species. Molecular epidemiology and serotyping studies have suggested that some variants are host specific; however, these associations have not been evaluated by cross‐challenging fish species ...

Meta‐analysis of major histocompatibility complex (MHC) class IIA reveals polymorphism and positive selection in many vertebrate species

open access: yesMolecular Ecology, Volume 31, Issue 24, Page 6390-6406, December 2022., 2022
Abstract Pathogen‐mediated selection and sexual selection are important drivers of evolution. Both processes are known to target genes of the major histocompatibility complex (MHC), a gene family encoding cell‐surface proteins that display pathogen peptides to the immune system.

Embracing nanotechnology for selenium application in aquafeeds

open access: yesReviews in Aquaculture, Volume 15, Issue 1, Page 112-129, January 2023., 2023
Abstract Selenium (Se) is an important micronutrient that has been used in aquafeeds for the normal growth, welfare and health of aquatic animals. Through nanotechnology, Se can be converted into nanoparticles that are more bioavailable, utilized and absorbed by aquatic animals.

Reproductive sterility in aquaculture: A review of induction methods and an emerging approach with application to Pacific Northwest finfish species

open access: yesReviews in Aquaculture, Volume 15, Issue 1, Page 220-241, January 2023., 2023
Abstract Aquaculture is the fastest‐growing food‐production sector and is striving to become a long‐term sustainable approach to meet the rising global demand for seafood. During the expansion and advancement of aquaculture, minimizing ecological impacts should occur concomitantly with maximizing production. Farmed fish, often genetically distinct from
