“…Vromant et al (2002a) obtained similar results for O. niloticus . However, B. gonionotus (Vromant et al 2002b) and T. pectoralis (Vromant, Nam & Ollevier 2001b), both able to feed on macrophytes, did not show different SGR‐values for different rice crop stages. Besides this, the inclusion of the variable ‘Log 10 O. niloticus SB’ in the C. carpio SGR multiple regression solution (Table 5) clearly suggests interspecific competition between the two species, confirming the findings of Vromant et al (2002a).…”

In the freshwater area of Vietnam's Mekong Delta, Barbodes gonionotus (Bleeker), Cyprinus carpio L. and Oreochromis niloticus (L.) are often reared together in rice ¢elds. The survival rate and speci¢c growth rate (SGR) of C. carpio showed a large variance. To understand the underlying reasons for this variation, we used multiple regressions for the variables SGR and survival rate, using the results of eight experiments in such polycultures at the Co Do rice^¢sh experimental station. The SGR of C. carpio declined with increasing rice density. Interspeci¢c competition with O. niloticus also had a negative e¡ect on C. carpio SGR.When fertilizer or manure is added to the trench of the rice^¢sh ¢eld or when extra food can be given to the ¢sh, O. niloticus seems more appropriate than C. carpio. The survival rate of C. carpio depended on season, C. carpio stocking weight and density and the biomass of wild ¢sh species. To obtain higher survival rates, one should stock fewer ¢sh but of a larger size, after thorough eradication of wild ¢sh species.

Growth and morphological development of laboratory-reared larval and juvenile snakeskin gourami Trichogaster pectoralis

2009

Morphological development, including that of fins, labyrinth organ, body proportions, and pigmentation, in laboratory-hatched larval and juvenile snakeskin gourami Trichogaster pectoralis is described. Body lengths (BL; mean ± SD) of larvae and juveniles were 2.3 ± 0.1 mm just after hatching (day 0) and 8.2 ± 0.6 mm on day 22, reaching 14.1 ± 2.3 mm on day 48. Aggregate fin ray numbers attained their full complements in juveniles [11.8 mm BL. Preflexion larvae started feeding on day 2 following upper and lower jaw formation, the yolk being completely absorbed by day 12. Subsequently, oblong conical teeth appeared in postflexion larvae [8.2 mm BL (day 16). Melanophores on the body increased with growth, with a large dark spot developing on the lateral midline at the caudal margin of the body in flexion larvae [6.1 mm BL. Subsequently, a broad vertical dark band from the eye to the caudal peduncle developed in postflexion larvae [8.9 mm BL. Proportions of head and pre-anal lengths became constant in postflexion larvae greater than ca. 9-10 mm BL, whereas those of maximum body depth, eye diameter, and snout length failed to stabilize in fish of the size examined in this study. First soft fin ray of the pelvic fin elongated, reaching over 40% BL. The labyrinth organ differentiated in postflexion larvae [7.4 mm BL (day 22). Comparisons of larval and juvenile morphology with another anabantoid species Anabas testudineus were also made, revealing several distinct differences, particularly in the numbers of myomeres and fin rays in the dorsal/anal fins, mouth location and body shape.

“…The nancial cost-bene t analysis of snakeskin gourami culturing has improved from approximately 13% (Chesoh 1995) to 58% (DOF 2021). There are local and global trades for frozen sh, chilled sh, juvenile sh, and aquarium sh, and most consumers know processed salted-sundried sh (DOF 2022) due to its tasty meat (Vromant et al 2001) and long-lasting preservation (Waiprib et al 2016). The snakeskin gourami boasts a comparatively higher market value than other tropical aquaculture species (Gustiano et al 2022).…”

Phenotypic variation in organisms arises from diverse sources, each with unique implications for adaptability to selection and environmental changes. This variation is particularly significant in tropical aquaculture, exemplified by the snakeskin gourami (Trichopodus pectoralis), a popular whole-body sale fish. Understanding these variations is crucial for optimizing animal breeding and commercialization efforts. This study explores previously uncharted territory by investigating the relationships among body weight (BW), total length (TL), body depth (BD), and Fulton’s condition factor (K) using 8,345 records of domesticated snakeskin gourami fish at the 9-month harvest point. Interrelationships between these traits and the associations between BW and other characteristics were examined and compared for each sex. Sexual dimorphism was evident, with females being significantly more extensive, and it showed higher variation and a stronger correlation between traits than males in all characteristics. The population was categorized into six market sizes (XL, L, M, S, XS, and XXS), with XXS being the most abundant (36.35%), followed by XS, S, M, L, and XL (31.95%, 23.30%, 8.06%, 0.31%, and 0.04%, respectively). There was mostly a male population in the XS and XXS size categories compared to a female population. Strongly significant correlations emerged (p < 0.0001), with BW highly associated with TL and BD and moderately associated with K. This study underscores the importance of understanding sexual dimorphism and trait correlations in domesticated snakeskin gourami for informing selective breeding and commercial strategies in tropical aquaculture.
