Özet
The objective of this study was to determine the length-length and length-weight relationships in Parapenaeus longirostris as a basis for conversions. Specimens were collected with hauls from the commercial trawler “Hapuloglu” between 9 and 12 December 2006 in Sιgacιk Bay and Kusadasι Bay in the Aegean Sea. Morphometric equations for the conversions of length and weight were constructed for females, males, and combined sexes. The equations for carapace length (CL), total length (TL), and body width (BW) for combined sexes were found as CL = 0.2296 × TL – 2.272, r 2 = 0.97, BW = 0.3708 × CL + 0.7694, r 2 = 0.91, and BW = 0.0861 × TL – 0.169, r 2 = 0.90, respectively. The length-weight relationship was determined as W = 0.0031× TL3.108, r 2 = 0.98 for total length and W = 0.546 × CL2.743, r 2 = 0.97 for carapace length. Males were generally smaller than females (K-S test; p 0.05). L'objectif de cette etude a ete de determiner les relations longueur-longueur et longueur-poids chez Parapenaeus longirostris pour servir de base de conversion. Les specimens ont ete collectes a l'aide des traits de filet par le chalutier commercial “Hapuloglu” entre le 9 et le 12 decembre 2006 dans les baies de Sιgacιk et Kusadasι, en mer Egee. Les equations morphometriques pour les conversions de la longueur et du poids ont ete etablies pour les femelles, les mâles et les sexes combines. Les equations pour la longueur de la carapace (CL), la longueur totale (TL) et la largeur du corps (BW) pour les sexes combines sont respectivement de: CL = 0.2296 × TL – 2.272, r 2 = 0.97; BW = 0.3708 × CL + 0.7694, r 2 = 0.91; et BW = 0.0861 × TL – 0.169, r 2 = 0.90. La relation longueur-poids a ete determinee comme W = 0.0031 × TL3.108, r 2 = 0.98 pour la longueur totale et W = 0.546 × CL2.743, r 2 = 0.97 pour la longueur de la carapace. Les males sont en general plus petits que les femelles (K-S test; p 0.05).
