Maturity is one of the most important biological parameters used in stock assessment programmes. Indeed, macroscopic stage gonadal development an essential feature estimating maturity ogive and spawning biomass. It also useful for determining season a species monitoring long-term changes cycle as well many other research needs related to biology fish. Despite efforts made during last few decades standardize data among all researchers, marine biologists continue without manageable unique...
Background. European hake, Merluccius merluccius, is a major predator in demersal ecosystem, and of great importance for the fishery. Knowledge feeding ecology fish species essential implementing multispecies approach to fishery management. Therefore this work was intended analyse stomach contents dietary changes according size, season, sex, depth better understanding ecological role Adriatic marine communities. Materials methods. A total 1646 specimens hake were collected Sea by...
The stomach contents of 1096 specimens Chelidonichthys lucerna were examined in order to analyse their diet composition according fish size, sex, depth and season. Sampling was carried out from May 2005 March 2007 during several bottom trawl surveys the Adriatic Sea (north-east Mediterranean). Feeding activity more intense juveniles than adults. most important prey Crustacea (mainly Decapoda: Brachyura, such as Goneplax rhomboides , Liocarcinus spp., Philocheras spp.) Teleostei European...
Summary Length–weight relationships were estimated for the first time seven species of gurnards (Triglidae) based on data collected over past 27 years in Adriatic Sea (northeast Mediterranean). Results show significantly different between juveniles and adults (females males combined) Aspitrigla cuculus, Eutrigla gurnardus, Chelidonichthys lucerna Lepidotrigla cavillone. Isometric growth is indicated four species, allometric all species.
Stomach contents of 283 anglerfish (Lophius budegassa), collected in the Adriatic Sea (north-eastern Mediterranean) from experimental trawl surveys 2005 and 2006, were examined to assess their diet as influenced by fish size, sex water depth. Changes food quantities stomach observed, percentage empty stomachs decreasing with increasing body size No differences found between male female diets. The is essentially an 'opportunistic feeder' that consumes mainly fishes, crustaceans molluscs....
Otolith and somatic mass of two Gadidae ( Merlangius merlangus Trisopterus minutus ) were compared in order to analyse the sex‐specific relationship between otolith growth at age. In present study, appeared a reliable indicator age both species. reflected growth, but these characters varied differed species sexes.
A multi-specific approach in fish diet studies provides insight into the complexity of trophic interactions marine communities. The feeding habits three gurnard species, Aspitrigla cuculus, Chelidonichthys lucerna and Eutrigla gurnardus (Scorpaeniformes: Triglidae), from north-middle Adriatic Sea were studied to evaluate prey-resource partitioning amongst species within comparing juveniles’ adults’ for each species. total 1818 specimens (390 A. 973 C. lucerna, 455 E. gurnardus) collected by...
In this study we investigated the spatio-temporal distribution of gurnards (8 species Triglidae and one Peristediidae) in northern Mediterranean Sea using 22 years MEDITS bottom trawl survey data (1994-2015). Gurnards showed significant differences terms abundance, dominance composition among geographical sub-areas ecoregions, with highest relative biomass (BIy) being found Malta, eastern Corsica, Balearic Islands Ionian Sea. The lowest BIy were observed highly exploited areas western...
Background. Red gurnard, Chelidonichthys cuculus (Linnaeus, 1758), is distributed in the Mediterranean Sea, Black and eastern Atlantic Ocean from Norway to Mauritania, although it rarely found North Sea on Norwegian shelf. The aim of this work was conduct a comprehensive study red gurnard Adriatic selected aspects population biology some its environmental implications. Materials methods. sampling covered entire subdivision GSA17 (north-central Sea) based several bottom trawl surveys MEDITS...
