“…More or less alike information has been published by earlier authors like (Azadi and Siddique, 1986;Marimuthu and Haniffa, 2007;Narejo et al, 2015) in Channa striata from elsewhere. Similar observation was also published by various workers in different fish species like Narejo et al (2006) in Gudusia chapra, Mastoi et al (2008) in Labeo calbasu, Chandio et al (2016) in Notopterusnotopterus, Bakht et al (2020) in Cyprinus carpio, Thebo et al (2022) in Ompokpabda, reported alike information related to the findings.…”

T he snakehead Channa striata (Bloch) is an airbreathing fish locally called as Shakur, Sol and commonly as Stripe Murrells is widely distributed in Asia and Africa (Narejo et al., 2015). It is commercially important, high-prized, carnivorous, fast growing and hardy fish could be reared with other cultured Abstract | Fecundity and gonadal periodicity of Channa striata from River Indus, near Jamshoro, Sindh, Pakistan was examined from 240 samples (120 for each sex) during October 2020 to September 2021.The experimental fish was procured from the commercial catch of local fisher community. The investigations were based on estimation of fecundity and its relationship with other body parameters, variation in egg size and calculation of gonadosomatic index. The results of fecundity estimation were based on 10 mature female fish ranging in size 30.4 to 43 cm and from 235.0 to 765.0 g in length and weight respectively. The lowest egg production (2193) was noted from small sized and highest was recorded (11830 eggs) from large fish. Egg production ability was noted ideally co-related by weight of ovary in relation to length and weight of fish. Egg size measurement reveals that the ova was noted to be increased in size during August to October (0.95 to 1.2 mm), after extrusion, there were no gonads during November to January and again start developing from February 0.1 to 1.2 mm that indicated that fish breeds onetime in year having peak during October. GSI values also showed similar trend of increasing the size of gonads from 0.2 to 2.0 and from 0.5 to 5.5 in both sexes. Lastly, it was decided that egg production capacity (fecundity) showed strong association with ovary weight in Channa striata from River Indus near Jamshoro as compared with other parameters.

“…Similar findings (140 -535) were also reported by Srivastava et al (2012) conducted in River Gomti for individuals of 18 -18.9 cm. Chandio et al (2016) worked on N. notopterus in Keenjhar Lake of Pakistan and reported a fecundity of 105 -1500 eggs in fishes of 18.5 -30.5 cm. In the present study, the relationship between fecundity and body length was found to be positively correlated with r = 0.54 which was less than that reported by Chandio et al (2016) who reported r value of 0.99.…”

Notopterus notopterus (Pallas, 1769) commonly known as bronze featherback is an important freshwater fish widely distributed in deep and clean waters in the rivers, beels, reservoirs and ponds. This study elucidates the length-weight relationship (LWR), relative condition factor and fecundity of N. notopterus collected from the river Brahmaputra in Dhubri, Assam, India. A total of 181 fish specimen were sampled. The LWR showed a positive isometric growth with uniform increase in height or width with increasing length. The value of a and b in males were 0.0120 and 3.06 respectively. In females, a and b were slightly higher being 0.0230 and 3.18 respectively. The coefficient of determination for combined sex was equal to 0.8572 (p < 0.001). The relationship between the fecundity and four variables viz. total length, body weight, gonadal length, gonadal weight were analysed and the relationship between the fecundity and gonad weight was much more significant than other variables considered. The current study might serve as a valuable guideline for establishing future biometric studies for fishes collected from this stretch of the river Brahmaputra.

“…The knowledge of fish reproduction is the most important in sustainable fisheries management, as well as to sustain fish processing business especially in Barito Kuala District. Numerous studies closely related to the featherback have been devoted to describe on reproductive biology [13,32,33], fecundity [6,34,35], genetic [36,37], length-weight relationship and condition factor [15,38], feeding habits [39,40], the age and growth [41], population dynamics [19], culture strategy [42,43] and conservation measures for this species [20,44]. In addition, Wibowo and Marson [37] reported that morphometric and meristic of N. chitala from Barito River, South Kalimantan were similar to those of C. lopis and N. notopterus from Kampar River, Riau Province, but genetically different from each other.…”

Featherback Fishery in Barito Kuala District, Indonesia: Potency, Business Opportunity and Challenge

Barito Kuala District is the largest producer of the featherback (Notopterus chitala) in South Kalimantan Province, Indonesia. It contributes about 42.29% of total regional fisheries production. Recently, supply and demand of raw material for fish chips processing business is completely dependent on the catch from the rivers. Ironically the capture fishery production for featherback tends to decline, which absolutely affecting on production volume and selling expense of the fish products. No commercial aquaculture supports this business, so far. Data on capture fishery, fish processing business and fish farming were tabulated and analyzed using descriptive method. There was a great market opportunity for featherback chips in this area of study, where the demand of fish chips (36 tons/year) was six times higher than the supply to the market (6 tons/year). The average annual profit received by the producer was USD 897. The Net Present Value (NPV), Internal Rate of Return (IRR), and Net Benefit Cost Ratio (Net B/C) were USD 2,796, 137%, and 4.59 with the Payback Period (PP) value was 8 months 15 days, indicating business was considered feasible and profitable, as well as has the favorable prospect. To increase the values, the culture business should be promoted. An attempt was made by Freshwater Fish Culture Center Mandiangin to culture them; however, the result are still being challenged to overcome this problem. The ideal interconnection of the three key issues was further discussed.
