“…During the current study, S. niger, S. curvifrons, C. diplochilus and G. holbrooki were observed with 'b' value less than 3.0 (b < 3), therefore showing a negative allometric growth pattern. The pattern of negative allometric growth with 'b' value of less than 3.0 has been reported earlier in S. niger (Bashir et al, 2016;Sheikh and Ahmed, 2019), S. curvifrons (Qadri et al, 2017), C. diplochilus (Mushtaq et al, 2016;Sidiq et al, 2021) and in G. holbrooki (Eagderi and Radkhah, 2015). However, C. carpio, C. carassius, P. conchonius showed a positive pattern of allometric growth with b >3.0.…”

For aquaculture assessments, the length-weight relationship and condition factor are considered as standard methods for determining fish growth, its health and the potential yield. A year-long study was conducted to calculate length-weight relationships (LWRs) and condition factor (K) for seven fish species, Schizothorax niger (Alghad or snowtrout), S. curvifrons (Sattar snowtrout), Cyprinus carpio (Common carp), Carassius carassius (Crucian carp), Pethia conchonius (Rosy barb), Crossocheilus diplochilus (Kashmir latia) and Gambusia holbrooki (Mosquito fish) in Manasbal Lake. The results revealed that four captured fish species (S. niger, S. curvifrons, C. diplochilus and G. holbrooki) exhibited negative allometric growth, while other fish species (C. carpio, C. carassius, P. conchonius) exhibited positive allometric growth. LWR was significant at P < 0.01 in all seven fish species, with a coefficient of determination (R2) ranging between 0.73 to 0.96. The K was higher in C. carpio than C. carassius, P. conchonius, G. holbrooki, C. diplochilus, S. niger and S. curvifrons. The current study providing the LWRs and condition factor of seven fish species from Manasbal Lake, Kashmir will be helpful for the management of fish species as well as for assessing the ecological condition of the Lake.

“…The authors have recently reported uniform spermatogenic capacity in both the principal (September-October) and residual (February-March) breeding seasons in male S. plagiostomus (Purohit et al, 2022). Nonetheless, the seasonal variations in annual ovarian cycle of S. plagiostomus observed were not fully consistent with that reported for other Schizothoracine species found in Kashmir valley, e.g., S. curvifrons (Qadri et al, 2019) andS. niger (FAROOQ et al, 2018) rather differed in terms of time of occurrence and duration.…”

“…Nonetheless, the seasonal variations in annual ovarian cycle of S. plagiostomus observed were not fully consistent with that reported for other Schizothoracine species found in Kashmir valley, e.g ., S. curvifrons (Qadri et al ., 2019) and S. niger (FAROOQ et al ., 2018) rather differed in terms of time of occurrence and duration. For example, the maturing or developing or pre‐spawning or spawning phase was observed in July–August and September–October in S. plagiostomus , which was found during November–December and March to April for S. curvifrons (Qadri et al ., 2019) and S. labiatus (FAROOQ et al ., 2018), respectively. The spent/regressing/post‐spawning phase was initiated during the onset of winter (November–January) in S. plagiostomus unlike S. labiatus (July–August) (FAROOQ et al ., 2018) and S. curvifrons (May–August) (Qadri et al ., 2019).…”

“…Numerous reports are available on the oocyte maturation and ovarian development in freshwater teleosts (Basu et al ., 2004; Chaube et al ., 2022; Malison et al ., 1994; Shein et al ., 2004; Singh et al ., 2008). Nonetheless, limited studies have been undertaken till date to understand the ovarian cyclicity of Cyprinidae fishes (Hliwa et al ., 2017; Manorama & Ramanujam, 2017; Sivakumaran et al ., 2003), including Schizothoracine species like Schizothorax richardsonii (Agarwal et al ., 2004; Bisht & Joshi, 1975; Ciji et al ., 2021; Joshi et al ., 2016), Schizothorax labiatus (Arafat & Bakhtiyar, 2022; FAROOQ et al ., 2018; Farooq et al ., 2019), Schizothorax niger (Hussain et al ., 2018; Malhotra, 1970; Sabha et al ., 2017), Schizothorax curvifrons (Qadri et al ., 2019; Sunder, 1984), Schizothorax plagiostomus (Agarwal & Singh, 1991; Arif et al ., 2019; Jan & Ahmed, 2019; Pasha et al ., 2016; Shrestha & Khanna, 1979; Singh et al ., 2016). Furthermore, the nomenclature and terminology used for identifying the ovarian developmental stages/maturational phases in teleost fishes by various authors are overlapping, and thus remain indistinct and confusing (Agarwal et al ., 2004; Agarwal & Singh, 1991; Arafat & Bakhtiyar, 2022; Arif et al ., 2019; Bisht & Joshi, 1975; Ciji et al ., 2021; FAROOQ et al ., 2018; Farooq et al ., 2019; Hliwa et al ., 2017; Hussain et al ., 2018; Jan & Ahmed, 2019; Joshi et al ., 2016; Malhotra, 1970; Manorama & Ramanujam, 2017; Pasha et al ., 2016; Qadri et al ., 2019; Sabha et al ., 2017; Shrestha & Khanna, 1979; Singh et al ., 2016; Sivakumaran et al ., 2003; Sunder, 1984).…”

Schizothorax plagiostomus, commonly known as snow trout, is a popular food fish found in parts of Central Asia and the Indo‐Himalayan region. Despite such a broad range of distribution and potential financial value, it is a highly neglected cold‐water ichthyofauna. Furthermore, an alarming decline in Schizothoracine population has been reported in the recent past due to climate change and uncontrolled anthropogenic interference. In this study, the seasonal variations in ovarian architecture and development were examined in adult S. plagiostomus from Garhwal Himalayan region, Uttarakhand, India. Ovarian‐somatic index ranged from 16.86 ± 0.29 to 0.31 ± 0.56, with a maximal value in September and a minimal value in April. Ovarian histology revealed the abundance of primary growth oocytes in resting and preparatory stages; primary/secondary vitellogenic oocytes with numerous cortical alveoli were predominant in the developing stage of pre‐spawning ovaries; secondary/tertiary vitellogenic oocytes were conspicuous in actively spawning ovaries; and atretic follicles/oocytes were discernible during the regressing stage of spent ovaries. Scanning electron microscopy of mature ova (mean diameter 2.003 ± 0.01 mm) prominently showed the structure micropyle (mean diameter 12.93 ± 3.38 μm). Fecundity analyses suggested that September was the principal breeding season, whereas residual spawning occurred with fresh rain in late winter during February–March. Collectively, this is the first comprehensive qualitative and quantitative report of the seasonal variations in the ovarian development and function for S. plagiostomus. These data may provide valuable information towards the captive breeding programme as well as conservation and management for Schizothoracine fishes in normal and altered climatic conditions.

“…Morphometric characters considered as measurable structures and are characters describing different external body parts of fish. These characters commonly used in fish biology studies to measure discreteness between different fish stocks (Qadri et al, 2017), and to detect phylogeny of the fish population (Turan, 2004).…”

This study aims to investigate the relationships among morphometric characters of Wels catfish with total length and find the best model to assess relationships. A total of 198 fish samples was caught in Sıddıklı Dam Lake between September 2015 and August 2016 in this study. The morphometric measures taken were: Total length (TL), Anal fin length (AFL), pectoral fin rays length (PFRL), body height (BH), head length (HL), and head height (HH). No significant differences were noted between the pectoral fin rays (PFRL) of females and males, while the significant differences were observed in the other morphometric measurements (TL, AFL, BH, HL, and HH) of females and males. The linear and non-linear model were used to determine relationships between morphometric characters and total length. The linear model is the best fit for all relationships, so this model is preferred for all calculates. All relationships were highly significant (P < 0.001, r 2 > 0.81) and the mean percent prediction errors were less than 10%. We found that AFL, PFRL, BH, HL, and HH are a good indicator for fish total length and are important for determining the length of Wels catfish. However, the best model was the relationship between anal fin length and total length for estimation of fish length in males and females. The data of the study provides novel information on relationships between morphometric characters for Wels catfish.
