“…Similarly, linear relationships between fecundity and weight have been reported by other authors (Arthi et al, 2013;Mir et al, 2013;Rao, 1981;Sarkar et al, 2009). In addition to the above, several other studies (Bindu et al, 2012;Buragohain and Goswami, 2014;Gupta et al, 2014) have reported significant relationship between fish length, body weight and ovary weight and fecundity in other catfish viz. Horabagrus brachysoma, Clarias magur and Ompok pabda.…”

This study demonstrates the comparative pattern of reproductive parameters viz. sex ratio, size at first gonadal maturity, gonadosomatic index (GSI), fecundity, egg dimension of O. bimaculatus analyzed from 13 different rivers during 2011-2013. It was observed that females start to mature earlier than males and mean size at first maturity in male and female varied considerably between the different populations. The reproductive period of fish were extended from April -August while in Southern rivers it was extended from March to July. The results indicated three types of reproductive patterns of O. bimaculatus in terms of age at first sexual maturity and absolute fecundity and distinct variation was observed across different rivers. The meanabsolute fecundity varied significantly between the rivers and was grouped in to three categories: (i) high absolute fecundity (ii) medium fecundity and (iii) low fecundity. The results indicated significant and positive correlation between absolute fecundity and total length, body weight and ovary weight in all the rivers (P<0.05). The oocyte distribution during the maturity season was consistent within the ovary but more fluctuations were observed within different population. This study provides quantitative account in to the comparative reproductive potential and inter-population reproductive strategies for the first time.

“…Gonads were weighed to the nearest 0.1 g (gonad weight, GW). Gonad development stages were distinguished according to color, relative size, and the presence of vitellogenic oocytes in females or milt in males (West, 1990;Lehodey et al, 1997;Bindu et al, 2012).…”

“…Reproductive strategies in fishes often reflect local adaptation to environmental and ecological conditions (Murua and Saborido-Rey, 2003;Thorsen et al, 2010). Therefore, a thorough understanding of the life history traits is of great significance in conservation biology (Bindu et al, 2012).…”

Reproductive biology of Chinese minnow Hemiculterella sauvagei Warpachowski, 1888 in the Chishui River, China

SummaryThis study describes the reproductive biology of the Chinese minnow Hemiculterella sauvagei. The length-weight relationship, sex ratio, spawning season, size at first maturity, and fecundity were analyzed based on 685 specimens collected from the Chishui River between July 2011 and July 2012. The relationship between standard length (SL) and body weight (BW) were estimated as BW = 2.14 9 10 À4 9 SL 2.801(R 2 = 0.839; N = 413; P < 0.05) for females and BW = 1.31 9 10 À4 9 SL 3.001 (R 2 = 0.868; N = 272; P < 0.05) for males. The female to male sex ratio, 1.52 : 1, differed significantly from a 1 : 1 ratio. Females predominated in standard lengths >12 cm. Analyses of the monthly variation in the gonadosomatic index (GSI), the monthly proportions of macroscopic gonadal maturity, and the size distribution of oocytes consistently suggested a prolonged spawning season of H. sauvagei from March to August, with a peak from April to May. Logistic curves describing the relationship between proportion of maturity (P r ) at each length interval and standard length were estimated as P r = 1/(1 + e 26.867-0.306SL ) (R 2 = 0.999; N = 413; P < 0.05) for females and P r = 1/ (1 + e 10.522-0.142SL ) (R 2 = 0.999; N = 272; P < 0.05) for males. Size at first maturity was estimated as 7.4 cm for males and 8.8 cm SL for females. Absolute fecundity varied from 563 to 5052, with a mean of 2413 AE 874 oocytes per ovary. The relative fecundity was estimated to be 41-299, with a mean of 171 AE 55 oocytes per ovary. The present study provides useful information for fishery management and resources conservation.

“…Based on the pattern of development and ovulation of oocytes, Tyler and Sumpter [36] defined two spawning patterns: single batch and multiple batches. For instance, golden catfish, Horabagrus brachysoma, was typical of single batch species due to its single peak of oocyte diameter distribution [23]. Likewise, A. nigrocauda has a unimodal distribution of oocyte diameter indicating that it is a single batch species.…”

“…For each gonad, its maturity stage was classified as: (1) I, undeveloped; (2) II, early developing; (3) III, later developing; (4) IV, mature; (5) V, spawned; and (6) VI, spent [22]. The gonad development stages were distinguished according to gonad color, relative size and the presence of vitellogenic oocytes in females or milt in males [23][24][25] ( Table 1). Females with vitellogenic oocytes were considered mature.…”

Reproductive characteristics of Ancherythroculter nigrocauda, an endemic fish in the upper Yangtze River, China

Knowledge on the reproductive biology of fishes is critical for understanding a species' life history and devising appropriate management strategies. Anthropogenic forces, such as damming and overfishing, threaten fishes endemic to the upper Yangtze River. We conducted a study on the reproductive biology of an endemic species, Ancherythroculter nigrocauda in order to provide information on the life history of this species and to assist in its conservation. From July 2011 to June 2012, a total of 417 fishes were captured via monthly sampling by fishermen in the Longxi River, a tributary in the upper Yangtze River. Although the female-male ratio was 1:1.03, females were predominantly larger in body size. Gonad somatic indices and oocyte diameter distribution showed that the spawning period of A. nigrocauda in the Longxi River ranged from April to August, with the peak in April. Body length at 50 % sexual maturity of A. nigrocauda was estimated to be 125 and 106 mm for females and males, respectively. Absolute fecundity of A. nigrocauda varied between 11,300 and 504,630 eggs, with the mean of 162,377 eggs. In conclusion, A. nigrocauda mature early, spawn once, and are highly fecund, all of which are consistent with an r-selected life history. It is recommended that a moratorium on fishing this species be enacted and the culture of this species be continued.
