    Aim: This study examines the feeding ecology and trophic biology of endangered ornamental fish Botia striata in the Koyna River, Western Ghats, India. The objective was to quantify diet composition, feeding intensity, and somatic indices to elucidate ecological adaptability and inform conservation, sustainable trade, and captive breeding strategies. Methodology: A total of 360 specimens were collected monthly from August 2023 to July 2024. Morphometric measurements were taken, followed by gut content analysis using frequency of occurrence, volumetric, and preponderance index methods. Feeding intensity was assessed through fullness and emptiness indices, while nutritional and reproductive status were evaluated using VSI, GaSI, HSI, GSI, and RGL. Results: Feeding intensity varied seasonally, with empty guts (23.83%) and full guts (19.44%) predominating. Diet comprised aquatic plants/detritus, diatoms, green and blue-green algae, cladocerans, copepods, insect larvae, molluscs, and other zooplankton. Volume-wise, cladocerans (28.22%) and copepods (22.32%) dominated. The preponderance index identified cladocerans as the principal food item. The mean somatic indices indicated balanced energy storage and reproductive condition. Interpretation: B. striata is a carni-omnivorous generalist, exhibiting trophic plasticity and seasonal feeding variation linked to reproduction and environmental factors. The findings support its ecological resilience and provide a baseline for conservation planning, habitat management, and aquaculture development.

    Aquatic Research, 2025
    Fish growth is a significant factor in fish production and is directly related to the income of fish farmers. Thus, in the present study, it is aimed to determine the growth status of the Indian major carp (Catla catla Ham. 1822) at Keliya reservoir (Gujarat). The morphometric measurements (total length and weight) were taken from 597 fish specimens that were randomly collected from commercial catches between November 2021 and March 2022. During the study, the total length ranged from 25.00 to 46.00 cm (34.41 ±0.16 cm), and the weight ranged from 206.00 to 1525.00 g (528.29 ±8.62 g) of fish was recorded. The length frequency of fish shows that the population was dominated by the length group 30-35 cm (307), followed by the length group 35-40 cm (170), 25-30 cm (75), 40-45 cm (41) and 45-50 cm (4). The total length and weight variables were used to calculate the length-weight relationship and condition factor. The value of the correlation coefficient (r2) was 0.906, showing a positive relationship between the variables, and the regression coefficient (b, 3.164±0.041 at 0.05 CI, which fulfilled the ‘cube law’ and indicates positive allometric growth of the studied fish in earthen ponds. The mean value of condition factor (K) for length groups A (25-30 cm), B (30-35 cm), C (35-40 cm), D (40-45 cm), E (45-50 cm) and pooled population were 1.26±0.02, 1.3 ±0.01, 1.25 ±0.01, 1.33 ±0.02, 1.39 ±0.09 and 1.24±0.01 respectively, which indicated that the condition of fish was good. The aquatic environment was conducive for fish survival in the studied water body.

  • Effect of stocking density on shooter formation, growth and survival of Asian seabass Lates calcarifer (Bloch, 1790) during nursery rearing

    Indian Journal of Fisheries, 2023
    Seabass Lates calcarifer is an important brackishwater fish, which thrives and farmed infresh and saline water environment. Differential growth of this species during larval andnursery rearing phases leads to the formation of shooters, which reduces overall survival dueto cannibalism. Therefore, the present experiment was conducted to evaluate the effect ofstocking density on shooter formation, growth and survival of seabass. Hatchery producedseabass seed (total mean length 1.76±0.39 cm; mean weight 0.132±0.10 g) were stocked innet cage hapa (2x1x1 m) installed in brackishwater pond, at four different stocking densities,viz., T1 (800 nos.), T2 (850 nos.), T3 (900 nos.) and T4 (950 nos.) in triplicates. During the45 days of nursery raising, fishes were fed with formulated nursery feed (crude protein: 42%and lipid 8%) at 5 to 8% of body weight three times a day. Initially, the fishes were manuallygraded on 3rd day and later on weekly basis and transferred to separate hapa. Total numberof shooters formed during grading periods (S1, S2, S3, S4 and S5) were counted. It wasobserved that though maximum shooters were obtained from treatment T1 and minimumin treatment T3, the shooter formation among different treatments were not significantlydifferent. The maximum numbers of shooters were obtained during the period from 9 to21 days of rearing in nurseries in all the treatments. A survival of 60% was recorded duringthe present study. Based on the results of this study, it is suggested to maintain stockingdensities of 400-425 m-2 for nursery rearing in hapa. Also, the rearing period from 9 to 21days is significantly critical for ensuring good survival rate.

  • LENGTH-WEIGHT RELATIONSHIP AND CONDITION FACTOR OF VILLAGE POND-REARED EXOTIC FISH (Cyprinus carpio Linnaeus, 1758)
    N.C. Ujjania, Niharika P. Shah, Ankit D. Patel, S.D. Prajapati
    Applied Biological Research, 2022
    The present study was aimed to assess the length-weight relationship and condition factor of exotic common carp (Cyprinus carpio). The morphological measures i.e., total length and weight of randomly selected 306 specimens of common carp, obtained from from Atgam village pond Valsad (Gujarat), were measured in January 2021. The fish were divided into four length groups i.e., A, B, C and D at length distance of 5.0 cm. The result showed that the fish length and weight in population was in the range of 21.3 to 38.3 cm and 205 to 259 g, respectively. The length frequency was 34, 79, 104 and 89 for groups A, B, C and D, respectively which revealed that lgroup C was dominant in the population, followed by group D, B and A. The length and weight variables were positively correlated (r2 = 0.886) and growth constant or regression coefficient was 2.804 revealing that the growth of fish was negative allometric that was considered abnormal growth as the weight increment was less with respect to fish length. The mean value of condition factor for group A, B, C, D and pooled population were 1.77 ± 0.03, 1.29 ± 0.01, 1.41 ± 0.02, 1.40 ± 0.01 and 1.41 ± 0.01, respectively, which indicated that the condition of fish was good in the aquatic environment. The information generated may help in ecological and biological management of fish for enhanced production and revenue generation in village ponds.

    The present study elucidated the length-weight relationship and condition factor of the Indian major carps catla Catla catla, rohu Labeo rohita and mrigala Cirrhinus mrigala from the Vallabhsagar Reservoir, Gujarat. The mean total lengths (TL) recorded for the three species during the study were, 40.734±0.614, 39.285±0.892 and 38.010±0.925 cm while mean weights (WT) recorded were 914.141±46.672, 969.306±93.738 and 635.714±51.129 g for catla, rohu and mrigal, respectively. The length and weight variables showed linear relationship as depicted by correlation coefficient (r) values of 0.987 in catla, 0.956 in rohu and 0.967 in mrigal. Growth in the three species was found to be positive allometric and exponent values (b) obtained were 3.104, 3.342 and 3.049 for catla, rohu and mrigal respectively. The condition factor (K) and relative condition factor (Kn) estimated revealed the well being of fish and conducive environment of the reservoir. Results of the study provided baseline information which would be helpful for the scientific management of Indian major carp fisheries in the Vallabhsagar Reservoir in Gujarat.
