Abstract
Length weight relationship parameters were determined for 17 fish (Arnoglossus kessleri, Blennius ocellaris, Callionymus lyra, Cepola macrophthalma, Citharus linguatula, Lesueurigobius friesii, Merluccius merluccius, Lophius piscatorius, Merlangius merlangus, Gobius niger, Mullus barbatus, Solea solea, Spicara maena, Serranus hepatus, Trachurus trachurus, Trachurus mediterraneus, Uranoscopus scober) species in the Marmara Sea. Fish samples were collected monthly bases between September of 2011 and July of 2014 with a beam trawl. The growth type of each species were determined and the calculated b values changed in range from 1.2565 to 3.4018.
Highlights
The morphometric relationships especially length and weight parameters are highly crucial for fisheries science, and population stock assessment studies
The demersal fish distributed in the Sea of Marmara has under the influence of high fishing pressure and benthic pollution. According to these restricted factors related the growth, we aimed to reveal the updated length and weight relationships of species representing of the demersal life of the Marmara Sea
The fish species, number of individuals, size intervals and mean values, coefficient, exponent values of length-weight relationship parameters, the standard error of the b, the correlation factor (r2) and the growth types are presented in Table 1 for each species, respectively
Summary
The morphometric relationships especially length and weight parameters are highly crucial for fisheries science, and population stock assessment studies. It gives information about the growth type of fish, whether growth is isometric or allometric. Some of other previous studies were conducted relating the length and weight relationship of fishes in the Sea of Marmara (Keskin and Gaygusuz, 2010; Bok et al, 2011; Demirel and Dalkara, 2012), these studies were approached in a confined geographical area. In addition to this, Demirel and Dalkara (2012) were studied at 17 stations in the Sea of Marmara
