Influence of sex and maturity state on trace elements content in liver and muscle of the Sciaenidae Totoaba macdonaldi.

ABSTRACT:

Background

The fish Totoaba macdonaldi is endemic to the Upper Gulf of California. Its migratory movements involve sites with high levels of trace elements in the environment that can accumulate in tissues. In this study, lead (Pb), copper (Cu), cadmium (Cd), zinc (Zn) and iron (Fe) concentrations in male and female totoaba liver and muscle were quantified at various sexual maturity stages along the species' geographic distribution.

Methods

Generalized linear models were used to explore associations between trace element concentrations and season of the year, sex/maturity stage, and total fish length.

Results

No detectable Pb concentrations were recorded in liver or muscle; Cu, Cd, Zn and Fe contents in totoaba liver and muscle were typical of fish inhabiting a
