Weight-length relationships are presented for 60 fish species captured from Izmir Bay, Central Aegean Sea. Samples were collected using bottom trawls (mesh sizes 24 mm at stretched cod-end). The b values W ¼ aL b showed a mean value of 3.027 (SE ¼ ±0.03) and more than 50% of the values ranged between 2.912 and 3.189. One species, Cepola macrophthalma, showed strong negative allometric growth.

The present work was aimed at determining the growth parameters of the garfish, Belone belone, a commercially important pelagic fish species in Izmir Bay (Aegean Sea). A total of 347 garfish specimens was collected during the period January-December 1997 from purse-seine boats operating in Izmir Bay. Fork length and total weight of the specimens ranged from 26.0 to 54.5 cm and from 16.51 to 281.73 g, respectively. Maximum age group determined was V for females and IV for males. Female : male ratio was 1 : 0.45. Most specimens belonged to age group II. The von Bertalanffy growth equations for length and weight were L t ¼ 62:71ð1 À e À0:237ðt þ 1:566Þ Þ for both sexes.

Age and growth of the hollowsnout grenadier was studied based on samples collected seasonally in the Agean Sea between March 2003 and January 2004. Total length ranged from 9.0 to 21.6 cm. Length-weight relationship was described as a ¼ 0.0032, and b ¼ 3.008. Age determinations based on otolith readings were between 1 and 10 years. The von Bertalanffy growth curve fitted to observed lengths-at-age provided parameters of L ¥ ¼ 24.9 cm, k ¼ 0.115 and t o ¼ )3.494.
