“…Ovarian histological analysis is one of the best ways to observe the sexual maturity and gonadal development of broodstock during the reproductive period. Numerous scientists [ 23 , 51 , 52 ] stated that histomorphological characteristics of the ovary provide important details on the stages of oocyte development and peak spawning season. The histological results showed that all the oocytes in the female ovary did not develop at a time, reflecting that this fish had an asynchronous ovarian oocyte development.…”

Long-whiskered catfish Sperata aor is a freshwater catfish known for its supreme flesh quality and fast growth, whose captive-reared broodstock denotes a difficult challenge for aquaculture. The reproductive dysfunctions in long-whiskered catfish raised in tank conditions were observed by comparing tissue biochemical composition and ovarian histology of wild female broodstock. Sixty (60) female broodstocks were used in the current study, consisting of 30 reared at sandy-muddy soil tank bottoms in captive conditions and 30 wild individuals collected from the haor basin during the breeding season. The fish reproductive state was investigated using the biometric and reproductive parameters, biochemical composition and levels of amino acids in the different tissues, and histological analysis of ovarian development. Results revealed that the biometrical parameters of wild and captive female broodstocks exhibited no remarkable difference (p > 0.05). Nevertheless, the wild fish had remarkably higher (p < 0.05) GSI (8.73%), oocyte weight (0.45 mg/egg), and ripeness (27.08%) in comparison with captive-reared broodstock. The total length and body weight, body weight and ovary weight, ovipositor diameter and ovary weight, and GSI and HSI displayed a positive relationship with R2 = 1, R2 = 1, R2 = 0.993, and R2 = 0.973, respectively, for wild broodstock, while R2 = 0.994, R2 = 0.806, R2 = 0.804, and R2 = 0.896, respectively, for captive broodstock. Additionally, the proximate composition in oocytes and liver tissues in both broodstocks did not differ significantly (p > 0.05). However, two essential amino acids (EAA), i.e., lysine and phenylalanine, and two non-essential amino acids, i.e., glutamic acid and glycine, were highly significant differences (p < 0.05) in the oocytes and liver of wild broodstock compared to the captive-reared broodstock. On the other hand, the EAA, e.g., isoleucine, threonine, leucine, and arginine, were highly dominated in both wild and captive female brood oocytes and liver. The ovarian histological slides from each fish group showed three oocytes developmental stages that indicated the asynchronous-reproductive ovarian oocytes of this fish. This study may be useful to fully understand the factors affecting the spawning and reproduction of S. aor broodstock, crucial for management in captive conditions as well as conservation and protection for sustainable aquaculture management of S. aor.

“…The spawning season of longtail tuna in Thailand waters occurred in May and August (Hassadee et al, 2014), in Indian waters occured in October-November (Abdussamad et al, 2012), and in the waters of Taiwan around December (Wei et al, 2011). The diversity of the spawning season and periodicity exists due to the varied ecological environments (Agarwal, 2008;Jega et al, 2018;Papoulias et al, 2006). The water temperature, photoperiod, and prey items may influence the spawning season of fish (Tormosova, 1983;Papoulias et al, 2006;Ma et al, 2012).…”

“…Lambert (2008) said that fecundity varies in relation to parental quality (size, condition), food availability, as well as environmental and evolutionary factors (stock biomass, fishing pressure). Jega et al (2018) stated that the differences in fecundity and reproductive potential were affected by the size of fish, food availability, temperature, salinity and genetics.…”

Longtail tuna (Thunnus tonggol) is one of common economically important pelagic fish species in Indonesia. The objective of this study is examining the biology of reproduction, consisting of length of weight relationship, sex ratio, maturity stage, gonado somatic index (GSI), length at first capture, and length at first maturity and spawning pattern. A total of 633 longtail tuna, ranging 29-58 cmFL and consisting of 293 males and 340 females, were collected from the Java Sea between April 2018 and March 2019. The results showed that the longtail tuna growth pattern was isometric. The sex ratio was not significantly different between male and female. The length of first capture longtail tuna of drift gillnet (43.2 cmFL) was bigger than the length at first maturity (42,3 cmFL). This indicates that the most of longtail tuna caught by drift gillnet have already spawned. The peak’s spawning season occurred in May and November, with fecundity ranging from 783,597 - 1,579,160 eggs. Longtail tuna has multiple spawning pattern

“…According to Jega et al [10] and Indarjo et al [9], the cause of the deviation from a 1:1 sex ratio is unidentified but it may have been impacted by differences in fish growth between the sexes as well as food availability and abundance. The dominance of females may be due to migration of female specimens to breeding site or may be fishermen are setting their gears close to breeding ground.…”

“…Fecundity, on the other hand, is a reproductive biology pathway that exhibits variation in the degree of production leading to an increase in the amount of fish captured [8]. For the assessment of commercial potentialities, stock study, life history, particular culture, and fishery management, in-depth and accurate information of fish fecundity is essential [10]. The representation of male and female fish in a population is revealed through studies on sex ratio.…”

Studies on fish biology are important because they help determine the best management strategy to use in order to conserve fish species in their natural habitat. Thus, some aspects of the Biology of Sarotherodon melanotheron and Tilapia guineensis in the Mahin Lagoon were covered in this study. For the study, 121 fish samples were collected. The sex ratio of S. melanotheron (1:1.64) and T. guineensis (1:1.36) showed no significant deviation from the expected 1:1. Fecundity ranged from 243 to 1223 in S. melanotheron and 156 to 600 in T. guineensis with means of 344.39±166.85 and 286.27±114.85 respectively indicating low fecundity in both species. Observed Gonado-Somatic Index (6.40±3.25% for T. guineensis and 5.65±3.31% for S. melanotheron) suggested the peak of gonad maturity. The regression equation of the length-weight relationship indicated that S. melanotheron exhibited negative allometric growth in male (b=1.66, R2=0.63), female (b=2.80, R2=0.83) and combined sex (b=2.55, R2=0.78) while T. guineensis exhibited positive allometry in male (b=3.05, R2=0.97), female (b=3.04, R2=0.95) and combined sex (b=3.04, R2=0.96). The condition factor was greater than 2 for both species. This study also revealed that the fecundity of the two species was size dependent. Examination of stomach fullness revealed that 4.2% and 0.0% of S. melanotheron and T. guineensis had empty stomachs while 20.0% and 3.8% had full stomachs respectively. This study therefore established that the study area was conducive for the fish. Monitoring and regulation of the fisheries is therefore recommended for conservation and management of the study area.
