Length-length and length-weight relationships in Nephrops norvegicus from the Aegean Sea (Linnaeus, 1758)

Abstract

The objective of this study was to determine the length-length, length-width and length-weight relationships in Nephrops norvegicus as a basis for conversions. A total of 659 specimens were collected with trawl gears from the commercial trawler Hapulo lu between the 17th and 21st August 2008 in international waters of the middle Aegean Sea. Morphometric equations for the conversions of length and weight were constructed for females, males, and combined sexes. Females were generally smaller than males, and size-frequency distributions total length (TL), carapace length (CL), and body width (BW) revealed significant differences between females and males.
