ABSTRACT

Some biological aspects of the Lizardfish, Saurida tumbil, from the Persian Gulf, Iran, were studied by regular monthly collections. A total of 173 specimens, including 17 immatures, 26 males, and 130 females from the Khozestan coasts were collected with a bottom trawl. Females ranged from 26.1 to 59.0 cm (38.7±6.8) in total length and from 126.5 to 1510 g (477.1±260.8) in weight. Males ranged from 26.3 to 38.3 cm (32.7±3.2) in total length and from 128.3 to 450.5 g (260.2±83.5) in weight. The slope of the regression line suggested an isometric growth for the fish. The gut content consisted mostly of fish species and the relative length of the gut (RLG) was 0.45 on average, suggesting a carnivorous feeding habit. The absolute fecundity was 74,444-250,452. The gonadosomatic index showed two peaks for the females (March and October), perhaps indicating that the species is a spring and autumn spawner.

    • "Condition factor values for males, were the highest in November and December and the lowest in September and August, while for females the highest values were in April and October and the lowest in February and December. This factor has not been studied before in I. hormuzensis to compare with, but usually it is higher in females and in non-spawning fish (Soofiani et al., 2006, Asadollah et al., 2014). "

    ABSTRACT: The reproductive biology of the Iranian cichlid, Iranocichla hormuzensis Coad, 1988, was investigated for 13 consecutive months in lower Mehran River, from August 2008 through August 2009. Four hundred and eighty six individuals (252 males and 234 females) were captured using a seine net (5 mm mesh size). The observed sex ratio was 1M:0.93F (χ², df = 1, P = 0.414). Mean ± SD of total length (TL) values in females and males were 62.08 ± 6.51 and 70.34 ± 8.16 mm, respectively. The frequency of 56-65 mm size class was higher in females and the 66-75 mm size class in males. A gonadosomatic index (GSI) analyses of females indicated that the reproductive period was during February-June, with a peak in March. Fecundity was best correlated with total body mass (M) (linear regression, r2 = 0.62) condition factor (linear regression, r2 = 0.62) and total length (TL) (linear regression, r2 = 0.56). The absolute fecundity ranged between 48-167 eggs with a Mean±SD of 107±35.2. Egg diameters ranged from 0.58 to 2.93 mm.

    ABSTRACT: A total of 691 specimens (114 males, 538 females and 39 immature) were collected from Bushehr coastal waters of the Persian Gulf, from February 2007 to February 2008 to study the reproduction of this species along with its gonad histological development. Mean absolute and relative fecundity was 263162 ± 31046 and 273 ± 27, respectively. The ova diameter ranged between 6 µ and 875 µ with a mean of 318 µ. The curvilinear relationship between fecundity and total weight was F = 2657.8 W 0.6617. Monthly changes in the gonadosomatic index exhibited a higher value in May and October in both sexes (P ≤ 0.05). Observations on the seasonal distribution of maturity stages and seasonal fluctuations in the gonadosomatic index confirmed recent findings that the spawning periods have 2 peaks, a higher in May and a lower in October. The Hepatosomatic index and GSI fluctuations were similar in females, but different in males. Males and female of Saurida tumbil reach the first sexual maturity at 25.5 and 27 cm, respectively. The sex ratio was 1M:5F (P ≤ 0.001). The simultaneous presence of postovulatory follicles and yolk globules in some ovaries indicated that this species is a multiple spawner.

    ABSTRACT: The Great lizardfish is one of the commercial demersal fishes in the Persian Gulf and Oman Sea. In this study the food preference index (FPI), Fullness index (FI) and stomach contents of Saurida tumbu were evaluated to assess the quantity and kind of food which this species consumes in the study area. The samples were collected monthly from commercial bottom trawl fisheries in main fishing grounds of eastern Strait of Hormuz. A total of 346 specimens were collected during the years 2009-2010 of which 269 specimens were female and 77 specimens were male. The minimum and maximum total length were 161 and 590 mm, respectively with the highest frequency in length group of 350-370mm. Results showed that 20.9% of stomachs were full, 18.9% were semi-full and 60.2% were empty. The main stomach contents (FPI=80.2%) were fishes and minor stomach contents (FPI=25.7%) were crustacean (Specially crab and shrimp) and cephalopods were found as random food. The minimum and maximum FIs were 2.5 and 42.5 in December and September respectively; and the overall CV was 60.2. The results indicate that this fish is a relatively frugal species which consumes fishes as main food and there is no difference in feeding of male and female.
