“…The values obtained for L ∞ (99 cm for males; 69 cm for females) appear to be realistic, as the largest male and female caught during the samplings had total lengths of 85.0 cm and 69.0 cm, respectively. Pazira et al. (2005) reported growth parameters for the Mesopotamian spiny eel from southern Iran as L ∞ = 92.3 cm ( K = 0.081 year −1 ) for males and L ∞ = 87.3 cm ( K = 0.082 year −1 ) for females.…”

“…Knowledge on M. mastacembelus ecology and biology is rather limited . Coad (1987, 1995, 1996) studied its taxonomy and distribution; however, the only study on growth properties of the species was in southern Iran (Pazira et al., 2005). Two studies dealt with histological and embryological properties (Gezen et al., 2005a,b; Şahinöz et al., 2006).…”

Age at length, growth and reproduction of 220 Mastacembelus mastacembelus specimens from the Atatu¨rk Dam Lake were studied from July 2005 to July 2006. Total lengths and weights ranged from 7.0 to 85.0 cm and from 6 to 1100 g, respectively. Maximum age was 13 years. The regression model fitted to length and weight data was W = 0.0228 L 2.43 for males and W = 0.0029 L 2.95 for females. The von Bertalaffy growth equations for males and females were L t = 99.2 [1)e )0.11 (t)0.12) ] and L t = 69.2 [1)e )0.26 (t)0.35) ], respectively. Males dominated especially at an older age; the overall sex ratio was 1 : 0.63 (M:F). The breeding period was from May to July. Fecundity ranged from 2540 to 24 000 eggs per female.

Abstract:Length-weight relationship of Macrognathus pancalus had been carried out from two different waterbodies of upper Assam during 2009-2011. The pool data for the co-efficient of regression (b) was recorded as 1.408 in juveniles; 2.977 in males; 3.034 in females. It reveals that females have better growth than males and juvenile. The 'b' for males was found to be minimum (1.408) in 6-9 cm and maximum (3.024) in15-18 cm whereas, for females the lowest (1.807) in 9-12 cm and highest (3.202) in >15 cm groups. In different seasons, the 'b' value ranged from 2.982 (premonsoon) to 3.253 (winter) for males while for females, from 2.825 (post-monsoon) to 3.571 (winter). It indicates that both the sexes did not follow the cube law (b=3). The higher condition factor 'K' for males (4.622) and females (4.362) were observed in 9-12 cm and lower values for males (4.128) and for females (3.961) were recorded in 12-15 cm and >15 cm length group. The maximum (4.282) and minimum (3.686) of 'K' for males were recorded in post monsoon and pre-monsoon while in female, the maximum (4.376) in monsoon and minimum (3.913) in winter. It reveals that the species were in good conditions. The 'r' values for in all cases were found to be highly correlated between length and weight.

“…Data on the growth of other mastacembelids are sparse but it seems that in Iran M. mastacembelus grows to about 160 mm in its first year (Pazira et al 2005), whereas in the warmer waters of Bangladesh M. armatus, a smaller species, grows to 145 mm in a year (Mustafa and de Graaf 2008). These values support the idea that the smaller specimens of M. vanderwaali, collected in the Batoka Gorge, were no more than a few weeks old.…”
