In the study sample of fish Byah (Liza macrolepis) from the Musa estuary in Khuzestan by tour Gvshgyr springs 20 mm size in a random
period of one year from November 2009 to October 2010. 449
fish Byah (Liza macrolepis) that were 300 male and species of fish
149 female were caught .Largest age group in the fish population in a
year were observed 19/37%.Two-year-old fish (+2) with a 30/51%, fish under a year (+0)
with 23/16%, three-year fish (+3) with 6/9% and four-year-old fish (+4) with
2/22% of the combined age were accounted
for. Two fish (+2), one year (+1) and under one year (+0) were observed in all
months sample combined of age. Three-year fish (+3) were sampled in all months
except May .Among the sampled fish with the maximum age was +4 years
old.Variation coefficient of fish+1, +2, +3 and +4, respectively 10, 5, 3/3 and
2/5 was observed. In attention that the
coefficient of variation of fish by age is less than 20 Determine the optimum
age of fish Byah (Liza macrolepis).
