| description | The unique hydrological and biological characteristics of Kalloni Bay (Panayotidis and
Klaoudatos, 1997) could affect the morphological and chemical characteristics of
economically important pelagic species, such as S. pilchardus. Aim of this preliminary study
was to investigate the morphometric and proximate characteristics of S. pilchardus
speciments caught in Kalloni Bay and to compare them with speciments from open sea areas
around Lesvos Island during a five-month period (mid-May to mid-October 2017). There was
a significant difference on both the length and the weight of the individuals and the
homogeneity of the samples between the Kalloni Gulf and the open sea areas. Variations for
both areas were evident among different morphological characteristics of the speciments and
the constituents of the proximate analysis that were determined during the sampling season.
The morphology of S. pilchardus in the Kalloni Gulf along with the condition indices that were
calculated and the proximate characteristics that were found during the laboratory analysis
indicate that the individuals might be of the same population but at a different maturity state.
Further research of this species in both the Kalloni gulf and the open Aegean Sea is substantial
due to the economic importance of S. pilchardus, especially in areas having a nursery role, and
will provide further useful information on the possible effects of hydrological and biological
characteristics in the Kalloni Gulf. |
