“…The main resource in the diet of S. porcus is Crustacea, predominating both in relative abundance and frequency of occurrence. This result is in accordance with Castriota et al (2012) where crustaceans accounted for 89% of the relative abundance of prey and 94.5% of the frequency of occurrence. Crustacean decapods are the main dietary components of S. porcus and other scorpaenids (Harmelin-Vivien et al , 1989; La Mesa et al , 2007; Castriota et al , 2012).…”

“…Most previous studies on this species have been carried out with fish collected in fishing grounds from Mediterranean areas (Gulf of Valencia: Morte et al ., 2001; Gulf of Naples: Zupo & Stübing, 2010), Adriatic Sea (Castriota et al , 2012) and Black Sea (Başçïnar & Saǧlam, 2009; Bilgin & Çelik, 2009; Demirhan & Can, 2009). On the Atlantic coast, specifically in the province of Cadiz, this species is mainly caught with bottom longlines.…”

Feeding ofScorpaena porcus(Scorpaenidae) in intertidal rock pools in the Gulf of Cadiz (NE Atlantic)

The present work on the feeding ecology of Scorpaena porcus according to season, sex and size, is the first study carried out in the rocky intertidal in the NE Atlantic. Previous studies were carried out with fish collected in fishing grounds from Mediterranean areas. A total of 106 fish were caught in monthly samplings from April 2008 to July 2010 in three areas of the rocky intertidal zone in the Gulf of Cadiz. The diet composition varied with season, size and sex. Shrimps were the main diet resource during all year, but other prey were also important depending on the season. As the size of fish increased, predation on smaller crustaceans decreased and consumption of larger crustaceans and fish augmented. Females and males based their diet on shrimps, while indeterminate fish fed largely on amphipods. No significant differences were found between feeding intensity and season, size and sex. Nevertheless, the PERMANOVA results showed that the number of prey is affected by the interaction between sex and size class. Our results highlight that S. porcus is a stenophagic species that shows a gradual segregation in the use of resources as it grows, which indicates there is no intraspecific competition in the rocky intertidal.

Black scorpion fish (Scorpaena porcus) is an important species for both artisanal and industrial fisheries in the Turkish Black Sea, with 306 tonnes landed in 2017. The diet composition of this species was investigated through the examination of their stomach contents. A total of 621 S. porcus (ranging from 12.79–765.5 g) were caught by trammel net in the south-eastern Black Sea (Turkish waters) from December 2015 to November 2016. The importance of prey items in the diet of S. porcus was assessed using the Index of Relative Importance (%IRI). Overall, the dominant species was the isopod Idotea balthica (52.8%IRI) followed by decapods (38.5%IRI) and teleosts (8.7%IRI). Seasonal variations in the diets were observed, with isopods predominant in autumn (>85%IRI), teleosts in winter (>77%IRI) and decapod crustaceans (>78%IRI) in spring and summer. The modified Costello's graphical analysis evinced a specialist feeding strategy for S. porcus during winter, spring and autumn while a shift to generalistic feeding strategy was exhibited in summer by a limited number of S. porcus individuals.
