| چکیده [English] | ||
| Survey was made for determination of some biological parameters of Yellowfin tuna in Hormozgan province (during 1995 to 1996) and it was determined that catch of above mentioned species in 1996 by gillnet was nearly 1133 tons. Comparing the length of the fish caught by industrial way with traditional way shows the bigger sizes were caught in industrial way. Yellowfin tuna was caught in the east Hormozgan strait specially Kouh-Mobarak and Gask to Meidani areas and the peak of hunting time was in April and September to December months. The maximum length of Yellowfin tuna was 158 cm and the minimum was 38 cm. The relationship between their weight and length was W=6.2 x 10-5 L 2.7283 . Their length and weight coefficient were estimated by these formula: L∞=181.62 cm, K=0.54 y-1 , and natural mortality, fishing mortality and total mortality are: Z=2.37, F=1.67 and M=0.70. | ||
