“…Other studies have also shown that there is a significant positive long‐term effect of using copepods as first feed with regard to growth in the older stages (Imsland, Foss, Koedijk, Folkvord, Stefansson & Jonassen ). Furthermore, it has been shown that production of copepods for the aquaculture industry is economically feasible in both intensive (Abate, Nielsen, Nielsen, Drillet, Jepsen & Hansen ) and semi‐intensive production systems (Abate, Nielsen, Nielsen, Jepsen & Hansen ).…”

This article analyses the challenges of different live-feed regimes for the rearing of marine finfish larvae and discusses the potential alternative live feeds to avert a future live-feed trap. Live feeds are indispensable for the successful rearing of larvae of most marine fish species. Brine shrimps (Artemia) and rotifers comprise the live feeds of choice in marine aquaculture today. However, their nutritional composition is deficient in especially essential fatty acids, and enrichment with fish oil is needed. Fish oil is considered a limited resource owing to its origin in fully exploited wild fish stocks. Moreover, fluctuations of the natural population of Artemia will, most likely, influence future availability and prices. This emphasizes the need for optimal exploitation of available live-feed resources and development of new sustainable alternatives, such as copepods. An array of solutions to these problems are presented to avoid a future live-feed trap and to reduce dependence on limited resources that influence future production possibilities, species diversification, price volatility and productivity in the aquaculture sector.

Abate, Nielsen, Nielsen, Drillet, Jepsen and Hansen () have also reported about the feasibility of massive egg production on A. tonsa , which suggested a great potential of developing commercial products of conservable copepod eggs of Acartia species. However, the induction of quiescent eggs is poorly studied with tropical copepod species.…”

“…Further, A. tonsa is an emerging model organism, with research published in a diverse array of scientific fields such as ecology, physiology, ecotoxicology, and animal behavior [11][12][13][14][15]. A. tonsa is also an emerging live feed species in aquaculture, where it could trigger natural predation behavior and supply optimal nutrition for the larvae of fish species with economic importance or which are endangered in the wild [11,[16][17][18]. Despite A. tonsa's multifaceted importance, partial versions of the mitochondrial cytochrome oxidase subunit I (COI) and the ribosomal 18S rRNA genes have been the only available genetic resources for A. tonsa until now [9,[19][20][21].…”

Members of the crustacean subclass Copepoda are likely the most abundant metazoans worldwide.Pelagic marine species are critical in converting planktonic microalgae to animal biomass, supporting oceanic food webs. Despite their abundance and ecological importance, only five copepod genomes are publicly available, owing to a number of factors including large genome size, repetitiveness, GC-content, and small animal size. Here, we report the sixth representative copepod genome and the first genome and transcriptome from the calanoid copepod species Acartia tonsa Dana, which is among the most numerous mesozooplankton in boreal coastal and estuarine waters. The ecology, physiology and behavior of A. tonsa has been studied extensively. The genetic resources contributed in this work will allow researchers to link experimental results to molecular mechanisms. From PCRfree WGS and mRNA Illumina data, we assemble the largest copepod genome to date. We estimate A. tonsa has a total genome size of 2.5 Gb including repetitive elements we could not resolve. The non-repetitive fraction of the genome assembly is estimated to be 566Mb. Our DNA sequencing-based analyses suggest there is a 14-fold difference in genome size between the six members of Copepoda with available genomic information through NCBI. This finding complements nucleus staining genome size estimations, where 100-fold difference has been reported within 70 species. We briefly analyze the repeat structure in the existing copepod WGS datasets. The information presented here confirms the evolution of genome size in Copepoda and expands the scope for evolutionary inferences in Copepoda by providing several levels of genetic information from a key planktonic crustacean species.
