This study was carried out to describe the feeding habits of Scorpaena porcus and to investigate the effect of sex, size
and season on their diet. Within the framework of this study, food preferences of 262 Scorpaena porcus (13±0.26 cm;
67±3.46 g) (±SE of means) which were taken from the stomach contents of fish caught at Trabzon coast (located at the South
– Eastern Black Sea coast, between November 2003 and January 2004) were investigated. Scorpaena porcus fed mainly upon
red mullet (Mullus barbatus) (IRI%=34.67) and mud shrimp (Upogebia pusilla) (IRI%=28.10), but also upon harbour crab,
brown shrimp, sea horse, and others. It was found that there were significant differences between its dietary habits in summer
and winter times (χ2=38.10, P<0.01). Scorpaena porcus, fed mainly upon harbour crab (IRI%=63.43) in summer and red
mullet (IRI%=57.46) in winter. As a result of statistical evaluation, red mullet, harbour crab and sea horse were found
statistically significant in their seasonal diet (P<0.05).
