“…In the Philippines, giant trevally is regarded as a high-value species, and thus has the potential to be used in aquaculture. In a study conducted by Mutia et al (2020), successful induced spawning of giant trevally in captivity was achieved after injecting human chorionic gonadotropin (hCG) at 1,000 IU/kg or luteinizing hormone-releasing hormone analogue (LHRHa) at 100 μg/kg into ripe female broodstock, while males received one-half of the female dosage.…”

“…(2.1) Source of broodstock: In most cases, broodstock are collected as juveniles or sub-adults from the wild and reared in captivity until maturation (see Table 3). Broodstock rearing often takes a long time, such as 3 yr (starting with 300 g fish) for greater amberjack (Fakriadis et al, 2019), 4-5 yr for giant trevally (Mutia et al, 2020) and 4 yr in captivity (Nogueira et al, 2018) or 7-10 yr (Watanabe et al, 1998) for white trevally. An exception is Florida pompano, for which wild-caught broodstock can spawn after 2 mth of captive rearing (reviewed by Weirich et al, 2021).…”

Importance of the work:Interest in marine fin-fish aquaculture has grown in recent decades in response to the rising demand for seafood. Objectives: To provide information and knowledge regarding aquaculture of carangid fishes and synthesize common features, followed by recommendations for development of aquaculture. Materials & Methods:The main literature sources used in this review were from SCOPUS and Google Scholar. Production data were from the Food and Agriculture Organization of the United Nations. All information and data gathered were analyzed and synthesized. Results: Of the 148 carangid fish species, 13 contribute a substantial proportion of global aquaculture production. The two most valuable species are pompano (Trachinotus ovatus), mainly produced by China and Japanese amberjack or yellowtail (Seriola quinqueradiata), mainly produced by Japan. This review provided an overview of aquacultural practices for each species and revealed that the following characteristics are common to carangid aquaculture: culture was first established using wild fingerlings; the success of hatchery production of fingerlings requires lengthy rearing of broodstock; availability of commercial artificial feed is another key success factor; diseases and parasites can be devastating and very difficult to control; and market constraints can have major adverse impacts. Main finding: The following recommendations were made: 1) development of fry production technology is a priority; 2) stocks should be genetically improved to cope with diseases and parasites; 3) cost-effective and environmental-friendly artificial diets should be developed; 4) cost-effective, land-based recirculating aquaculture systems should replace sea-cage and pen culture; and 5) new species, such as bluefin trevally, should be developed for aquaculture to diversify production.

“…The giant trevally, specifically, is known to be highly tolerant of freshwater environments. This feature renders this species highly interesting for aquaculture [ 4 – 6 ] and makes it an ideal candidate species to investigate linkages between genotype and phenotype in the context of the freshwater adaptation of marine fishes [ 7 , 8 ] . Caranx ignobilis is an apex predator in tropical and subtropical reefs and coastal environments in the Indian and Pacific Oceans [ 9 ] , and is heavily targeted by small-scale and recreational fisheries throughout its range.…”

Caranx ignobilis, commonly known as giant kingfish or giant trevally, is a large, reef-associated apex predator. It is a prized sportfish, targeted throughout its tropical and subtropical range in the Indian and Pacific Oceans. It also gained significant interest in aquaculture due to its unusual freshwater tolerance. Here, we present a draft assembly of the estimated 625.92 Mbp nuclear genome of a C. ignobilis individual from Hawaiian waters, which host a genetically distinct population. Our 97.4% BUSCO-complete assembly has a contig NG50 of 7.3 Mbp and a scaffold NG50 of 46.3 Mbp. Twenty-five of the 203 scaffolds contain 90% of the genome. We also present noisy, long-read DNA, Hi-C, and RNA-seq datasets, the latter containing eight distinct tissues and can help with annotations and studies of freshwater tolerance. Our genome assembly and its supporting data are valuable tools for ecological and comparative genomics studies of kingfishes and other carangoid fishes.

Caranx ignobilis, commonly known as the kingfish or giant trevally, is a large, reef-associated apex predator. It is a prized sportfish, targeted heavily throughout its tropical and subtropical range in the Indian and Pacific Oceans, and it has drawn significant interest in aquaculture due to an unusual tolerance for freshwater. In this study, we present a high-quality nuclear genome assembly of a C. ignobilis individual from Hawaiian waters, which have recently been shown to host a genetically distinct population. The assembly has a contig NG50 of 7.3Mbp and scaffold NG50 of 46.3Mbp. Twenty-five of the 203 scaffolds contain 90% of the genome. We also present the raw Pacific Biosciences continuous long-reads from which the assembly was created. A Hi-C dataset (Dovetail Genomics Omni-C) and Illumina-based RNA-seq from eight tissues are also presented; the latter of which can be particularly useful for annotation and studies of freshwater tolerance. Overall, this genome assembly and supporting data is a valuable tool for ecological and comparative genomics studies of kingfish and other carangoid fishes.
