Length-weight relationships, condition factors and relative weight of five fish species of Bushehr waters, Northern Persian Gulf

Abstract

The aim of this study was to record the length-weight relationship parameters and condition factors for some commercially important fish of Bushehr coastal waters of Persian Gulf. The length-weight relationships were calculated for five species caught during fishing surveys using different types of fishing gears (trawls, pots and gill net with different mesh size) during April 2008 to December 2010. The b value ranged between 2.733 for Argyrops spinifer and 3.03 for Epinephelus coioides. The coefficient of determination (r 2 ) was very significant for all the species. Relative weight had significant differences (Kruskal-Wallis test, P<0.001) with best performance by E. coioides. This results show that this range size of specimens in these populations apparently do not reach and surpass 100% of mean weight. In this study, length-weight relationships and condition factors are reported for the first time for A. spinifer, Pomadasys kaakan and Lutjanus malabaricus from the Persian Gulf and for Lethrinus nebulosus and Lutjanus malabaricus ruber which has not been previously recorded in the Iranian waters.

Growth pattern, condition and prey-predator status of 9 fish species from the Arabian Sea (Baluchistan and Sindh), Pakistan

“…But a very few study was conducted on condition factors of these species. Fulton's condition factor for E. coioides (Raeisi et al, 2011) andA. latus (Awan et al, 2017) were smaller than our current findings.…”

Length-weight relationship of two fish species from Cholvar River, western Iran: Mastacembelus mastacembelus (Banks & Solander, 1794) and Glyptothorax silviae Coad, 1981

“…Information on length–weight relationships of Iranian fish fauna is limited to some reports on commercially important species (Hosseini, : Naddafi et al., : Shokri et al., : Esmaeili, ; Esmaeili and Ebrahimi, : Abdoli et al., : Heydarnejad, 2009; Alavi‐Yeganeh et al., : Raeisi et al., ; Bibak et al., ). Two species of M. mastacembelus and G. silviae are native to the Cholvar River, Iran.…”

Life-history traits variation of Lutjanus malabaricus (Bloch & Schneider, 1801) in the waters off Northern Vietnam

“…Several studies have addressed basic life-history traits, age, growth, maturation and spawning of the Malabar blood snapper across southern, central and western parts of its range (Edwards, 1985; Newman et al ., 2000, 2002; Andamari et al ., 2004; Fry et al ., 2009; Fry and Milton, 2009; Masood and Farooq, 2011; Raeisi et al ., 2011; Mazumder et al ., 2016; Ernawati and Budiarti, 2019; Nurulludin et al ., 2019; Rapi et al ., 2019, 2020; Wibisono et al ., 2019; Ben-Hasan et al ., 2021). According to these studies, the life-history parameters of L. malabaricus may vary significantly, depending on the region.…”
