“…Sriyadi (2017) listed the following seven criteria for determining the super red Arowana: colour (30 points), body form (30 points), overall view performance (20 points), mouth and burble (5 points), eyes (5 points), pectoral fin (5 points), and dorsal, anal and caudal fin performances (5 points). Based on these criteria, colour is a priority for Arowana fish, with various scientists also stating that colour influences the price of ornamental fish (Ahilan et al 2008;Gouveia and Rema 2005;Sun et al 2012;Wang et al 2006;Yang et al 2012;Yuangsoi et al 2010;Yue et al 2020). The colour of a fish reflects the many pigments in its chromatophores cells, of which there are five types: melanophores, erythrophores, xanthophores, leucophores and iridophores (Fujii 1993(Fujii , 2000Goda et al 2011;Sköld et al 2016).…”

This study aimed to evaluate the effect of crickets enriched with a source of carotenoids on fish’s growth, colour, and total carotenoid content in juvenile Asian Arowana (Scleropages formosus). Six juveniles were fed with different enriched crickets (G. sigilatus) based on the following treatments: (A) Crickets fed with fish feed without enrichment, (B) Crickets fed with fish feed containing 500 ppm of synthetic astaxanthin, and (C) Crickets fed with a combination of 50% fish feed, 48% sand crab meal and 2% marigold petal meal. The results of the study revealed that The weight gain (WG), specific growth rate (SGR), feed efficiency (FE), length gain (LG), and survival rate (SR) for treatment A were 110 g, 1.16% head/day, 45.79%, 10.98 cm, and 100% respectively. There was also no significant difference (P>0.05) with the other treatments. However, treatment B had a positive effect on the redness (a*) of the Arowana tail with a value of 9.52, and treatment C increased the yellowness (b*) of the Arowana body with a value of 2.77 (P<0.05), which was different to the other treatments. There were no differences between any of the treatments concerning the effects on lightness (L*), chromaticity (C*), and hue (H*) on either the body or the tail. The astaxanthin enrichment produced the highest carotenoid content (P<0.05) with a value of 45.09 µg/g. Enriching crickets with astaxanthin influence colour and carotenoid content but not the growth of the Asian Arowana fish.

“…Second, similar to birds and mammals, the evolution of static allometric intercepts and slopes in Osteoglossiformes might have been channeled through enhanced parental investment [Iwaniuk and Nelson, 2003;Barton and Capellini, 2011;Tsuboi et al, 2018b]. Available data of life history traits in Osteoglossiformes [Okedi, 1970;Kirschbaum and Schugardt, 2002;Nguyen et al, 2017] suggest that the Arowana family Osteoglossidae has particularly advanced parental investment in the form of mouth brooding [Scott and Fuller, 1976;Merrick and Green, 1982;Verba et al, 2014], feeding of juveniles with skin secretion [Lüling, 1964], and extremely large eggs [Yue et al, 2020]. Therefore, it would be interesting to investigate how parental investments and relative brain sizes are related in Osteoglossiformes.…”

Exceptionally Steep Brain-Body Evolutionary Allometry Underlies the Unique Encephalization of Osteoglossiformes

Brain-body static allometry, which is the relationship between brain size and body size within species, is thought to reflect developmental and genetic constraints. Existing evidence suggests that the evolution of large brain size without accompanying changes in body size (that is, encephalization) may occur when this constraint is relaxed. Teleost fish species are generally characterized by having close-fitting brain-body static allometries, leading to strong allometric constraints and small relative brain sizes. However, one order of teleost, Osteoglossiformes, underwent extreme encephalization, and its mechanistic bases are unknown. Here, I used a dataset and phylogeny encompassing 859 teleost species to demonstrate that the encephalization of Osteoglossiformes occurred through an increase in the slope of evolutionary (among-species) brain-body allometry. The slope is virtually isometric (1.03 ± 0.09 SE), making it one of the steepest evolutionary brain-body allometric slopes reported to date, and it deviates significantly from the evolutionary brain-body allometric slopes of other clades of teleost. Examination of the relationship between static allometric parameters (intercepts and slopes) and evolutionary allometry revealed that the dramatic steepening of the evolutionary allometric slope in Osteoglossiformes was a combined result of evolution in the slopes and intercepts of static allometry. These results suggest that the evolution of static allometry, which likely has been driven by evolutionary changes in the rate and timing of brain development, has facilitated the unique encephalization of Osteoglossiformes.

“…188 The arowana industry in Malaysia is well developed, accounting for nearly half of the total value of the ornamental fish industry in Malaysia, and reached a peak of 47.45 million US dollars from nearly 317,000 individuals in 2009, of which about 80% were exported to China. 189,190 Due to the increasing scale and the technological improvements of arowana aquaculture stimulated by profit, the price of arowana has fallen in recent years, especially silver arowana. Based on field investigations by the authors, some individuals of silver arowana have been found in the wild in the Pearl River basin, probably as the result of abandonment or deliberate release by fish keepers.…”

Aquaculture, especially of non-native species and translocated domestic species, is a greatly encouraged way of relieving the conflicts between food and economic demand and resource depletion. We herein summarized the introduction history of non-native fish for aquacultural use in China, including 105 species introduced from abroad and 61 species translocated domestically across river basins, which has brought great economic benefits but high ecological risks. Of these, one-fourth have successfully established wild populations in natural waters and 15% have successfully invaded. We presented specific examples of seven aquaculture species/taxa and three aquarium species/taxa to explain their outcomes. The notable economic benefits, complex species composition and strain selection of tilapias, carps and sturgeons may together facilitate their invasion, and result in fish diversity decline, genetic pollution, and loss of ecosystem service. We specifically reviewed invasion cases in lakes and reservoirs and found that lakes in western China and reservoirs made by major This article is a Sena De Silva paper. The Sena De Silva paper is an honorific title dedicated to the memory of Professor Sena De Silva, who was the founding editor of Reviews in Aquaculture and a globally renowned aquaculture scholar, pioneer and advocate. The title is awarded to high quality articles that excel in one, or more, of the following qualities: i) Novelty and originality; ii) Likelihood of direct positive impacts for the aquaculture sector, with keen focus on any of, or all three: environmental sustainability, economic viability, and social responsibility iii) Overall quality of scientific reasonings coupled with realworld applicability.
