Interactive Effects of Temperature and Soybean Meal‐Based Diets on the Physiological Status of Juvenile Totoaba macdonaldi: Growth and Blood Parameters

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Growth and haematological parameters are used in aquaculture as indicators of the health of cultivated fish in response to changes in diet and the physicochemical conditions of the water. In this study, the physiological status of Totoaba macdonaldi was evaluated based on growth, haematological parameters and blood chemistry in response to two

Kyttyrälohi (Oncorhynchus gorbuscha) vieraslajina Pohjois-Euroopassa

, 2023
Tiivistelmä. Kyttyrälohi on pienikokoisin, mutta runsaslukuisin Oncorhynchus -suvun lajeista. Kyttyrälohella on erikoistunut kahden vuoden elinkierto, minkä seurauksena niille on muodostunut kaksi erillistä kantaa, jotka eivät lisäänny keskenään. Kyttyrälohen luontaiseen levinneisyysalueeseen kuuluu Tyynenvaltameren pohjoisosa ja siihen laskevat ...

Phenotypic Sorting of Pink Salmon Hatchery Strays May Alleviate Adverse Impacts of Reduced Variation in Fitness‐Associated Traits

Ecology and Evolution
Maladapted immigrants may reduce wild population productivity and resilience, depending on the degree of fitness mismatch between dispersers and locals. Thus, domesticated individuals escaping into wild populations is a key conservation concern.
