Population assessment and yield per recruit of longtail tuna (Thunnus tonggol) in Northern of the Persian Gulf and Oman Sea (Iran, Hormozgan Province)
The purpose of this paper was to detail some important biological aspects of T. tonggol in coastal waters of Hormuzgan Province(Persian Gulf and Oman Sea). A total monthly data of 4383 individuals ranging from 25 to 124 cm fork length were collected from April 2015 to March 2016. The data were analyzed with FiSAT II software using the ELEFAN1 package to estimate the population parameters. Th...
متن کاملLength frequency, length-weight relationship and catch per unit of effort (CPUE) of Longtail tuna (Thunnus tonggol) and Yellowfin tuna (Thunnus albacares) caught by purse seine in Oman Sea
Length frequency, length-weight relationship and catch per unit of effort (CPUE) for longtail tuna and yellowfin tuna in purse seine fishing were studied in Oman Sea between July and August 2015. Length range and mean of longtail tuna were obtained 56-98 and 74.13±0.41 cm, respectively. Length range and mean of yellowfin tuna were obtained 51-128 and 74.62±0.46 cm, respectively. The length-weig...
متن کاملDevelopment of Formaldehyde Biosensor for Determination of Formalin in Fish Samples; Malabar Red Snapper (Lutjanus malabaricus) and Longtail Tuna (Thunnus tonggol)
Electrochemical biosensors are widely recognized in biosensing devices due to the fact that gives a direct, reliable, and reproducible measurement within a short period. During bio-interaction process and the generation of electrons, it produces electrochemical signals which can be measured using an electrochemical detector. A formaldehyde biosensor was successfully developed by depositing an i...

متن کاملReproductive Biology of Albacore Tuna (Thunnus alalunga) in the Western Indian Ocean
The reproductive biology of albacore tuna, Thunnus alalunga, in the western Indian Ocean was examined through analysis of the sex ratio, spawning season, length-at-maturity (L50), spawning frequency and fecundity. From 2013 to 2015, a total of 923 female and 867 male albacore were sampled. A bias in sex ratio was found in favor of females with fork length (LF) < 100 cm. Using histological analy...
