متن کاملAggregation dynamics and foraging behaviour of striped red mullet Mullus surmuletus in the western Mediterranean Sea.
Habitat-related heterogeneity of striped red mullet Mullus surmuletus heterospecific foraging assemblages was examined off the coast of Spain. Video-based focal-follows conducted on 122 M. surmuletus assemblages (446 total individuals) revealed an array of attendant species (n = 7) with composition linked to benthic habitat complexity; bare sandy substrata were characterized by homospecific gro...
متن کاملDiscriminating stocks of striped red mullet (Mullus surmuletus) in the Northwest European seas using three automatic shape classification methods
Stock identification is of primarily importance for population structure assessment of economically important species. This study investigates stocks of striped red mullet using three automatic methods of stock identification based on otolith shape and growth marks. Otolith shape is known to be a promising approach for stock identification but interpreting patterns of variance is a difficult pr...
