“…Özaydın (unpublished * ) stated that the diet of the majority of P. acarne included Polychaeta, Mysidacea, Decapoda, and Amphipoda, throughout the Aegean Sea. However, Rizkalla et al (1999) reported that crustaceans, teleosts, and echinoderms constituted the main food items of axillary seabream in the Egyptian Mediterranean Waters. According to Morato et al (2001) the diet of 38 axillary seabream specimens with 21.0-28.0 cm FL from the north-eastern Atlantic, consisted of a wide variety of small organisms, mainly fishes and several invertebrates (Thaliacea and Ophiuroidea).…”

Background. The knowledge of the age, growth, and feeding ecology of fish species is essential for conservation, monitoring, and management activities required for the sustainable use of fish stocks. The objective of this work was to describe the growth and feeding of Pagellus acarne from the Gulf of İzmir, central Aegean Sea. The information provided in this study contributes to the knowledge which is for sustainable management applications. Material and methods. The study was carried out to investigate the growth and feeding characteristics of axillary seabream, Pagellus acarne (Risso, 1827), in the Gulf of İzmir, the central Aegean Sea, from commercial trawl fishery between October 2012 and September 2013. Age and growth were determined by annuli counts of sagittal otoliths. Length-weight relation and the von Bertalanffy equation were used to evaluate the fish growth. Percentages by number, weight, and frequency of each food category were determined, and the index of relative importance (%IRI) was calculated to define the main food categories. A similarity of diet was also examined according to a season and fish size. Results. A total of 2036 specimens' were analysed. The lengths ranged from 7.5 to 22.0 cm and the weights ranged from 4.55 to 138.45 g. For the age determination, a total of 547 left sagittal otoliths were extracted. The age ranged from 0 to 4 years. Von Bertalanffy growth parameters were determined from mean lengths of age groups and the following parameters were obtained:

“…Sixteen fish species were identified in its diet of which Spicara smaris and Spicara flexuosa (Family: Centracanthidae) are the main fish prey. Rizkalla (1992) and Faltas (1993) declared that picarels (Family: Centracanthidae) constitute a remarkable percentage in the catch of Egyptian bottom trawlers. The present result shows that S. smaris is eaten in large number during winter.…”

T he ej^mination-of 418 -stomachs of Uranoscopus scaber in the Egyptian Mediterranean waters showed that the feeding intensity had a maximum value during April (85%). Analysis of food contents revealed that this species is mostly carnivorous fish, that feeds on a broad food items including pisces, crustaceans, molluscs, echinoderms, annelids, algae and higher plants. Spicara smarts and S, flexuosa (Family: Centracanthidae) were the main fish prey in the diet of stargazers. The test of seasonal diversity index of food items exhibited high value during spring (H 5 = 1.43) than in other seasons, due to wide diversity of food. Regarding the feeding diversity according to size groups, it was found to be high for fishes of large size groups of more than 20.0 cm (H* = 1.41). The test of food overlap according to seasons showed significant overlapping among all seasons with exception between autumn and winter. Significant overlapping was found between all size groups (<15.0 cm, 15.0-20.0 cm and > 20 cm).

“…Out of 299 trawling operations in Alexandria Mediterranean waters, the cephalopods are represented about 9.8 % of the total fish catch landing, of which 6.1 % cuttlefishes, 3.5 % octopuses and 0.21 % squids (Riad, 1993). Investigation of 149 trawling operations in Alexandria Mediterranean waters in the period from 1986-1988, cuttlefishes, octopuses and squids were found to represent 6.13, 1.47 and 0.09 %, respectively of the total catch (Rizkalla, 1992). Worth mentioning is that the squid catch represents less than 10% of the total annual landing from the Egyptian Fishers (Riad and AbdEl-Hafez, 2008).…”

Reproductive biology of males and females Loligo forbesi were investigated from samples obtained from commercial catch caught by local fishermen using trawling nets. The samples were seasonally collected (548 individuals) between spring 2010 and winter 2011. The results of sex ratio indicated that females outnumbered males during peak periods of reproduction. Based upon morphological features of the gonads, two and five maturity stages for males and females were described, respectively. Depending on the proportion of each maturity stage, as well as various maturity indices (gonado-somatic index, G.S.I and nidamental-somatic index, N.S.I) the spawning season was found to take place during spring and early summer. The mean size at first maturity was 13 and 11.8 cm. dorsal mantle length (ML) for males and females respectively.
