Comparing dominance relationships and movement of native marble trout (Salmo marmoratus) and introduced rainbow trout (Oncorhynchus mykiss)

Abstract

Behaviour observations of the endangered native marble trout (Salmo marmoratus, Cuvier, 1829) and introduced rainbow trout (Oncorhynchus mykiss, Walbaum, 1792) in the laboratory and in a tributary to the Idrijca River in Slovenia were combined to study the movements and dominance relationships between individuals of the two species in an open field test. Under laboratory conditions, no difference between the species was detected for neither time spent actively or distance moved. In species

Structural and ultrastructural aspects of the skin of large yellow croaker Larimichthys crocea

“…The fish exhibit a variety of attractive skin colors and patterns, highlighting their uniqueness (Luo et al, 2021; Slominski et al, 2004). Furthermore, the skin color of fish, such as marble trout ( Salmo marmoratus ), coral hind ( Cephalopholis miniata ), and guppies ( Poecilia reticulata ), is an important economic characteristic (Galal‐Khallaf et al, 2019; Khoo et al, 1999; Pengal et al, 2023). Large yellow croaker ( Larimichthys crocea ) is an economically crucial marine fish in China (Weng et al, 2022; Zhang et al, 2021).…”
