To understand the functional meaning of morphological traits in the exploitation of natural resources, it is necessary to develop a quantitative, meaningful scheme for understanding ecophenotypes; this will facilitate management and conservation, which are the most pressing challenges in vulnerable aquatic environments. In this context, the managem...

Trace elements integrated into fish fin rays from the ambient environment may represent a permanent record of the environmental conditions that an individual has experienced throughout its lifetime. Fish from hatcheries used for stocking may therefore carry a natural intrinsic tag of their origin, which can be then later used for assessing the effi...

Demographic data of the great sturgeon, Huso huso, from the Iranian coastal waters of the Caspian Sea were derived from measurements of individuals with a fork length ranging from 84 to 255 cm, obtained from commercial fisheries.

Validation was a...

Kutum (Rutilus frisii) displays different egg colours during the spawning season, mostly due to the presence of carotenoid pigments. In this study, the authors investigated the relationship between the egg colour and muscle lipid of adult female kutum and the correlation between egg carotenoid content and the immune parameters of larvae. The result...

Because trace elements of otoliths are considered a natural marker capable of recognizing the chemical composition of ambient water and fish migration history, these elements could be potentially used to analyse the movement of reproductive (R) and non‐reproductive (NR) mature‐sized fish. Supposedly, it is not essential for NR individuals to migrat...
