Editorial: Live feed for early ontogenetic development in marine fish larvae

Abstract

Editorial on the Research Topic:Live feed for early ontogenetic development in marine fish larvae 1 PrefaceLive feeds hold the key to a stable and expanding marine aquaculture. In this editorial, we briefly review the history of live feed production for marine larviculture and summarize the latest contribution issued in the research topic -Live Feed for Early Ontogenetic Development in Marine Fish Larvae. With the current research that were submitted to this research topic, we see trends into many different aspects of live feed production. We are ensured that some of the remaining bottlenecks will be solved in a near future, providing a diverse and ecological sound marine aquaculture sector to flourish. Larviculture of marine fish speciesThe marine aquacultures are expanding with an increasing diversity of fish species across different regions. Most commercial marine fish larvae require live feed as first feeding diet, such as European seabass (Dicentrarchus labrax), gilthead sea bream (Sparus aurata), turbot (Scophthalmus maximus), Atlantic halibut (Hippoglossus hippoglossus) and cod (Gadus spp.) in Mediterranean and East Atlantic regions (Sweetman, 1992;

Density effects on a tropical copepod Acartia sp.: Implications as live feed in aquaculture

“…Copepod biomass production has become one of the major interests in aquaculture for the last two decades (Doan et al, 2018; Drillet et al, 2006, 2011; Grønning et al, 2019; Nguyen et al, 2020) due to the high nutritional value, size variations, and behavior of copepods which may be relevant for larvae of many aquaculture species (Drillet et al, 2006, 2011; Pan, Dahms, et al, 2022; Pan, Souissi, & Jepsen, 2022). Calanoid copepod species have high levels of highly unsaturated fatty acids (HUFA) which are essential for the normal development of marine fish larvae and juveniles (Drillet et al, 2006, 2008; Pan, Dahms, et al, 2022; Pan, Souissi, & Jepsen, 2022; Rasdi & Qin, 2016; Rayner, Hwang, & Hansen, 2017). However, copepod density is typically lower than 400 adult individuals L −1 tropical and subtropical aquaculture ponds (Blanda et al, 2015; Grønning et al, 2019) which typically results in low production and is still a major limitation of copepod biomass production (Grønning et al, 2019).…”

Spiny lobster feeding grounds: an eDNA metabarcoding assessment reveals a high level of plankton biodiversity in Tawang Bay, Indonesia

“…Numerous studies have shown that biological factors 45 such as plankton availability are important for the natural diet of lobster larvae (O'Rorke et al 2014), and marine plankton are important for most marine species including molluscs and fishes (Pan, Souissi, and Jepsen 2022). For instance, the plankton Oithona sp., which has 50 been previously reported to be abundant 30 areas of lobster larvae (Amin et al 2022a;Boudreau, Simard, and Bourget 1992;Lillis and Snelgrove 2010).…”
