International study on Artemia. XXV. Factors determining the nutritional effectiveness of Artemia: The relative impact of chlorinated hydrocarbons and essential fatty acids in San Francisco Bay and San Pablo Bay Artemia
vliz.be Abstract
Different Artemia cyst samples harvested from the San Francisco and the San Pablo Bay regions (California, U.S.A.), and suspect because of their poor nutritional performance in fish and crustacean farming, have been analysed for their chlorinated hydrocarbon and fatty acid content. These results have been correlated with survival, growth, and biomass production of larvae of the marine crustacean Mysidopsisbahia Molenock fed those different Artemia in a standard culture test. Differences in chlorinated hydrocarbon content do not correlate with differences in mysid culture performance. Fatty acid profiles reveal three groups of Artemia batches with high, intermediate, and low levels of the highly unsaturated fatty acid 20:5ω3. The production yield of the mysid larvae could be correlated with the relative level of the 20:5ω3 fatty acid in the Artemia nauplii.

Improved reproductive performance of tiger tail seahorse, Hippocampus comes, by mysid shrimp fed singly or in combination with other natural food
-Aquaculture International , 2015 - Springer VerlagThe brood size, parturition frequency and parturition occurrence of tiger tail seahorse, Hippocampus comes were evaluated for 180 days using single and combined diets comprising Artemia salina, mysid shrimp Mesopodopsis orientalis and frozen Acetes sp. The daily food intake of seahorse was determined with the following treatments: T1-Artemia; T2-mysid; T3-Acetes; T4-Artemia + mysid; T5-Artemia + Acetes ; T6-mysid + Acetes; and T7-Artemia + mysid + Acetes. Percent body weight (% BW) of daily food intake until satiation was similar in Artemia, mysid and Artemia + Acetes (20-22 %), but significantly higher in mysid + Acetes, Artemia + mysid, and Artemia + mysid + Acetes with 25, 31 and 33 %, respectively (p < 0.05). Single diet of frozen Acetes was least consumed at 6 %. Thus, mysid was the preferred food of adult seahorses as a single or combined diet with Artemia and Acetes. Diet treatments with single mysid or combined with Artemia and Acetes have significantly higher brood size (223-292) than the other treatments (107-152) (p < 0.05). Significantly longer parturition interval (60 days) was observed in seahorses fed with Artemia than those fed with mysid or in combination with other natural food (13-26 days), but not significantly different to seahorses fed with Acetes and Artemia + Acetes (42-45 days). Parturition occurrence in seahorse fed with Artemia, Acetes and Artemia + Acetes (2.7-4.3) were the lowest, while Artemia + mysid and Artemia + mysid + Acetes have significantly higher occurrence followed by mysids + Acetes and mysid only (p < 0.05). Thus, the reproductive performance was improved when seahorses were fed with single or combined foods including mysid. Total lipid was positively correlated to brood size and parturition occurrence, while DHA:EPA ratio was negatively correlated to brood size and parturition occurrence. -

Daily rates of ingestion on rotifers and Artemia nauplii by laboratory-reared grouper larvae of Epinephelus suillus
-The Philippine Scientist , 1994 - San Carlos Publications, University of San CarlosThe amount of rotifers and Artemia nauplii consumed daily by the grouper Epinephelus suillus larvae was determined through examination of gut contents. The larvae (2.6 mm TL) were initially fed rotifers on day 2 and newly hatched Artemia nauplii on day 21 (9.1 mm TL). The amount of food consumed by the larvae increased with larval growth. Larvae also showed diurnal feeding pattern at day 7 (3.6 mm TL), day 14 (4.9 mm TL), day 21 (9.1 mm TL) and day 28 (11.1 mm TL). Feeding incidence increased in the evening and became zero at 2100-2200 h. Active feeding started earlier in the older larvae and satiation was between 0900-1100 hr. -

Feeding habits of hatchery-reared grouper, Epinephelus suillus larvae
- In CL Marte, GF Quinitio & AC Emata (Eds.), Proceedings of the Seminar-Workshop on Breeding and Seed Production of Cultured Finfishes in the Philippines, Tigbauan, Iloilo, Philippines, 4-5 May 1993, 1996 - Aquaculture Department, Southeast Asian Fisheries Development CenterThe feeding habits of hatchery-reared Epinephelus suillus larvae were determined by examining their gut contents. The larvae (2.6 mm TL) were initially fed rotifers on day 2 and newly-hatched Artemia nauplii on day 21 (9.1 mm TL). The amount of rotifers initially ingested averaged 1.3 individuals/larva. The ingestion rate increased as larvae grew. Larvae immediately showed strong preference for Artemia to rotifers on the first day of introduction. E. suillus larvae showed diurnal feeding pattern at day 7 (3.6 mm TL), day 14 (4.9 mm TL), day 21 (9.1 mm TL) and day 28 (11.1 mm TL). Feeding incidence decreased in the evening and was nil at 2100-2200 h. Active feeding started earlier in older larvae and satiation was between 0900-1000 h. The results of this study will be used as a basis in developing a good feeding scheme for E. suillus larvae.
