“…The breeding season of C. striata appears to coincide with the rainy season and extends from May to August as evidenced by higher GSI values during this period. Some researchers have established relationships between HSI and GSI in fishes (Cantanhede et al 2007;Ghafouri et al 2019). According to Zardo and Behr (2015), gonad maturity and reproductive activity imply the use of materials obtained from ingested food and mostly from energy reserves deposited in different parts of the body.…”

The striped snakehead Channa striata is a valuable food fish and has a high market value. The feeding and natural breeding grounds of this economically important fish species have been reduced due to increasing anthropogenic activities and habitat alterations in the Gangetic River system. The present study was undertaken to assess the feeding and reproductive biology of C. striata, which is widely distributed in India and many other Asian countries (Pakistan, Bangladesh, Thailand, China, etc.). A total of 400 fish specimens were collected from three sites on three different rivers in Uttar Pradesh, India. Feeding habits, feeding intensity, gonadosomatic index, fecundity, maturity stages based on macroscopic studies, and sex ratio were examined. C. striata was found to be a carnivorous species (dominantly piscivorous). The feeding intensity varied according to season and fish size, with a higher intensity being observed during pre-spawning and post-spawning seasons. The reproductive biology of the striped snakehead from the Gangetic River system demonstrated that the gamete maturation occurred during May to July. The fecundity of C. striata ranged from 3652 to 48,450 eggs. Fecundity was linearly correlated with body length, body weight, and ovarian weight. The average ratio of males to females was observed to be 1:3.2.

“…After identifying the various stages of sexual maturation, diameter of sex cells was measured during different growth phases under magnifications of 40× by a scaled ocular micrometer. The stage of gonad maturity was determined visually following Brown-Peterson et al (2011) which is widely used in different works (e.g., Abaszadeh et al, 2013;Hamzeh et al, 2017;Siami et al 2017;Keivany et al, 2018a;Ghafouri et al, 2019). Reproductive seasonality was determined by examination of the monthly changes in the gonadosomatic index.…”

Some aspects of the reproductive biology of Planiliza abu (Mugilidae) were investigated by collecting of 428 specimens caught with trawl by local fishermen from Karun River, Ahwaz, from November 2016 to September 2017. The total length for males ranged between 10-17.1 (13.6±1.26 SD) cm and for females, between 10.5-17.3 (13.44±1.35) cm. The age range of fish in both sexes was between 0 + -7 + years and the most abundant age group was the 4 + . The sex ratio in the studied fish was equal (P>0.05). The mean egg diameter was significantly different (P<0.05) in different months and the individual size ranged between 0.12 and 0.57 mm. The absolute fecundity ranged from 3600 to 48600 eggs and the relative fecundity from 120 to 900 eggs per 1 g of body weight. The highest hepatosomatic index in females was in February during yolk vitellogenesis (1.89). Based on gonadosomatic index, egg diameter, and monthly distribution of ovarian maturation stages, the spawning season of this fish is long, but peaks in February (GSI 12.35) and March (GSI 12.18). This species appears to have a group synchrony reproductive pattern.
