“…For the sake of consistency, this comparison was restricted to freshwater fishes, as the water content of marine fish eggs is generally (much) higher. In eggs of freshwater fishes with V O > 20%, this ratio is about 3.5 ± 0.5 (mean ± SD , 8 spp., Akatsu, Ogasawara, & Yasuda, ; Parameswaran & Murugesan, ; Morioka, Ito, Kitamura, & Vongvichith, ; Morioka, Ito, & Kitamura, ; Morioka, Chanthasone, Phommachan, & Vongvichith, ; Morioka, Vongvichith, Phommachan, & Chantasone, ), whereas in other freshwater fishes producing eggs with no or small oil globule(s), this ratio is about 40% higher (mean ± SD of 5.0 ± 1.1; Mann–Whitney U ‐test; p < 0.0001; 107 spp., authors' unpublished data).…”

Here, on the basis of published information upon over 800 species from 39 orders and 202 families, we analyse how the size of oil globules in fish eggs varies between reproductive guilds and environments with contrasting salinities. About 80% of marine fishes produce eggs with oil globules, the volume of which (VO) never exceeds 9% of the egg reserves and averages 2%. These proportions vary very little between marine fish species producing pelagic or demersal eggs. Fewer freshwater fishes (about 40%) produce eggs with oil globules, but their globules are much larger (mean VO of 10%) and their volumes vary considerably between reproductive guilds: VO is on average 3–10 times lower in freshwater species with demersal eggs than among freshwater pelagophils and aphrophils (i.e., bubble nesters), where it averages about 40% (range of 23%–69%) of the egg reserves. These results support the idea that oil globules serve to hydrostatic lift in fresh waters, but not or very little in marine waters, where egg buoyancy can be achieved at a lower energy cost through egg hydration. Advantages and constraints of oil globules in fish eggs are discussed in the light of species producing eggs with very large oil globules (VO > 20%): access to oxygen‐rich water layers that are indispensable for egg development vs. smaller size of larvae at first feeding, since the saturated lipids contained in oil globules essentially serve very little to tissue construction.

“…The basic features of morphological development of this species have been described (Figures 1 & 2) [11]. Subsequent investigations of three anabantoid species, i.e., the snake skin gourami Trichogaster pectoralis [12] the three spot gourami T. trichopterus [13] and the giant gourami Osphronemusgoramy [14], compared morphological and behavioral development and the early biology of larval and juvenile stages ( Figure 3). Besides helping to improve seed production of these species, these findings are relevant to the ecology of related taxa.…”

A rich diversity of indigenous fish is present on the Indochinese Peninsula, particularly in the Mekong Basin. Since the 20 th century, a number of alien fishes have been introduced into the region primarily for the development of aquaculture, and there is increasing concern regarding the potential for loss of regional biodiversity and for a decline in the stock of indigenous fishes. Consequently, efficient utilization of indigenous fishes for aquaculture is desirable. Therefore, biological surveys are required to support their conservation. This article reviews research carried out by the author in Lao PDR into the early morphological development and biology of several indigenous fish species in relation to aquaculture development, fisheries management and species conservation.

“…The production of snakeskin gourami is still inhibited by the low survival and the slow growth of this species in the seed phase. The problem solving is pursued through numerous studies about biological reproduction (Oktafia et al, 2014;Ath-Thor et al, 2014), feed management (Murjani, 2011;Siswanto et al, 2016), and growth performance of the snakeskin gourami (Morioka et al, 2010).…”

Snakeskin gourami Trichopodus pectoralis an endemic fish that was highly demanded by Indonesian society. The declining in population stock was the main problem cause its availability still relies upon the nature catch. The increase of its production of culture was still constrained by the slow rate of growth and survival rate in the seed phase. This study aimed to determine the optimal salinity and its effect on growth performance, survival rate, osmotic activity, and blood description of the snakeskin gourami Trichopodus pectoralis. A complete randomized design (CRD) was used in this study with four different treatments and each treatment consisted of three replications. The salinity test consists of 0 g/L, 1 g/L, 3 g/L, and 5 g/L. The experimental fish sized at 0.49 ± 0.13 g and length 2.96 ± 0.42 cm with a stock density of 25 fish/aquarium (1 fish/L). During 28-day of rearing, the experimental fish was fed using Tubifex sp. as restricted based on the FR (5%) of biomass per weekly sampling. The results showed that the optimal survival rate and growth showed the best at salinity 3 g/L because it showed the most stable blood level so that the fish could avoid stress response. Keywords: salinity, survival rate, growth, hematological, Trichopodus pectoralis ABSTRAK Ikan sepat siam Trichopodus pectoralis merupakan ikan endemik yang sangat diminati masyarakat Indonesia.Pemenuhan kebutuhan ikan sepat siam masih mengandalkan hasil tangkapan dari alam sehingga populasi di alam mengalami penurunan. Peningkatan produksi ikan sepat siam dari budidaya masih terkendala dengan sintasan dan pertumbuhan yang lambat pada fase benih. Tujuan penelitian ini adalah menentukan salinitas optimum dan pengaruhnya terhadap performa sintasan, pertumbuhan, kerja osmotik, dan gambaran darah benih ikan sepat siam.Penelitian dilakukan dengan metode rancangan acak lengkap (RAL), empat perlakuan dan masing-masing3 kali ulangan. Perlakuan yang diujikan adalah salinitas 0 g/L, salinitas 1 g/L, salinitas 3 g/L, dan 5 g/L.Ikan yang digunakan berukuran 0,49±0,13 g dan panjang 2,96±0,42 cm, padat tebar masing-masing 25 ekor/akuarium (1 ekor/L). Selama 28 hari masa pemeliharaan, ikan sepat siam diberi pakan berupa cacing sutra (Tubifex sp.) secara restricted berdasarkan FR 5% dari biomassa per Sampling mingguan. Hasil penelitian menunjukkan sintasan dan pertumbuhan terbaik dihasilkan pada perlakuan salinitas 3 g/L. Hal itu diduga karena gambaran darah pada perlakuan 3 g/L stabil sehingga terhindar dari respon stres. Kata kunci: salinitas, sintasan, pertumbuhan, gambaran darah, sepatsiam
