“…The species has the potential to be used in aquaculture hatcheries as live feed for marine fish larvae as it tolerates a wide range of salinities and temperature (Grindley, 1981;Isla & Perissinotto, 2004). P. hessei also meet the recommended 2:1 DHA:EPA ratio (Siqwepu, Richoux, & Vine, 2017) required for developing marine fish larvae (Sargent, McEvoy, & Bell, 1997) and the nauplii of P. hessei is small enough (nauplii instar 2:168-360 µm) (Jerling & Wooldridge, 1989) to be ingested by the small mouths of first-feeding marine fish larvae. While aspects of cultivability of species from the family Pseudodiaptomidae have been investigated (Chen, Sheng, Lin, Gao, & Lv, 2006;Ohs, Rhyne, Grabe, DiMaggio, & Stenn, 2010;Rhyne, Ohs, & Stenn, 2009) the full potential of P. hessei has yet to be determined.…”

This study aimed to investigate the feeding behaviour (particularly gut fullness and evacuation, preying on rotifers and feeding preference in the water column) of the calanoid copepod, Pseudodiaptomus hessei, as a potential live feed species for aquaculture. Fed and starved, male and female P. hessei were fed rotifers (Brachionus plicatilis) in the presence and absence of microalgae for 24 hr. Starved copepods consumed more rotifers (11.31 ± 1.01, individual rotifers) than fed (8.06 ± 1.01, individual rotifers) while the number of rotifers consumed in the presence of microalgae was similar when fed or starved. Gut fullness and evacuation was determined by feeding copepods two different cell size microalgae species (Tetraselmis suecica and Isochrysis galbana). Gut fullness and evacuation percentage were observed under the dissecting microscope (as 0, 25, 50, 75 and 100%). Copepods fed on T. suecica (large cell) filled their guts more rapidly, while those fed on I. galbana (small cell) evacuated their guts faster. Feeding preference was determined using a multifactorial experiment where copepods were fed two microalgae species, T. suecica and I. galbana, each presented as benthic and planktonic food sources. P. hessei preferred to feed on planktonic microalgae first regardless of microalgae choice species for ±80 min, before shifting to benthic food source. This information can be used as baseline information for aquaculturists to rear the species as live feed for marine fish larvae.

“…Indeed, energy requirements for young larvae are estimated as 20 kJ per kilogram of diet (Zambonino Infante & Cahu, 2010). Many studies evidence that dietary deficiencies in Omega 3 highly unsaturated fatty acids (HUFA) such as DHA and EPA result in high larval mortality and reduced growth rate (Ali et al, 2007;Chatzifotis et al, 2010; Conceic ßão, Y ufera, Makridis, Morais & Dinis, 2010;Siqwepu, Richoux & Vine, 2017). Regarding the lipid requirements, C adernas (2011) recommends an intake about 17 wt.% of the diet for larval rearing.…”

“…The determination of the nutritional requirements of Sciaenidae species such as meagre has been the subject of several studies (Ali, Rharbi, Akharbache & Sedki, 2007;C adernas, 2011;Chatzifotis et al, 2010;Roo, Hern andez-Cruz, Borrero, Schuchardt & Fern andez-Palacios, 2010). Indeed, a DHA/EPA ratio of 2/1 is recommended to ensure the development and correct pigmentation of aquaculture species (Hamre et al, 2013;Siqwepu et al, 2017). Dietary lipid requirements are higher for other commercial species such as gilt-head bream (18%) and seabass (25%-30%) (Zambonino Infante & Cahu, 2010).…”

First-feeding diets employed in the rearing of meagre (Argyrosomus regius) larvae are based on live preys that are commonly enriched to compensate for their deficiency of essential fatty acids. A feeding trial was conducted on meagre larvae (Argyrosomus regius) fed rotifer (Brachionus plicatilis) and Artemia salina enriched in lipids from an emulsion of cod liver oil (CLO) and a commercial product (CP). The effect of both enrichment products was evaluated on the survival rate, size and lipid composition of meagre larvae. The results showed that larvae fed CLO presented significant higher values of survival rate (35.0 AE 3.2%) and larval size (12.06 AE 1.17 mm) at the end of the experiment, compared to the CP diet (26.0 AE 2.5%, 11.41 AE 0.91 mm, respectively). Both zootechnical parameters were related to the content of polyunsaturated fatty acids in the larvae. Indeed, the larvae fed CLO presented a higher ratio DHA/EPA than those enriched in commercial product (0.82 AE 0.18 and 0.38 AE 0.12 at 26 days after hatching, respectively). Both larval groups presented similar body content of arachidonic acid (1.4 wt.% on average at 26 days after hatching), regardless the enrichment source. From all above, we can conclude that the enrichment of live preys with an emulsion of cod liver oil is an economically viable alternative to commercial products. Indeed, cod liver oil emulsions are able to fully meet the requirements for fatty acids of meagre larvae.Furthermore, cod liver oil is easily available from fish processing facilities.

“…In most hatchery applications the exact requirement of microalgal biomass composition is still not completely known. Most hatcheries achieve the required dietary composition by mixing multiple microalgal species [7,[17][18][19], or by finding a strain that performs best in the selected application [20][21][22]. The nutritional value of microalgae for aquaculture applications is mostly attributed to the content of omega-3 fatty acids.…”

“…Rhodomonas sp. is an important microalga for aquaculture as it is often used in live feed applications, specifically for copepods [32,90] [20,55,92,93]. These fatty acids are specifically essential for fecundity, egg-production and copepod transformation [94].…”
