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
Buen-Ursua, Shelah Mae A.; Azuma, Teruo; Arai, Katsutoshi; Coloso, Relicardo M. (Springer Verlag, 2015)The 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. -
Use of bacteria as biological control agent against microbial diseases in shrimp (Penaeus monodon) and crab (Scylla serrata) hatcheries: Part II. Application of probiotics in natural food and artificial feeds
Lavilla-Pitogo, Celia R.; de la Peña, Leobert D.; Catedral, Demy D. (Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)The suitability of probiotic bacterial incorporation into artificial diets was tested with inferior results due to the interference of heat-resistant starins that are associated with several feed ingredients. However, probiotic bacterial application into the live natural foods like the rotifer, Brachionus plicatilis, and Artemia franciscana nauplii is promising due to the ease in incorporation and insignificant effects on their survival. Probiotic bacterial incorporation into both Brachionus and Artemia was successfully done within 3 hr of exposure. The strain C1 probiotic bacteria had positive influence on both the microbial flora of the rearing water and the animals. Preemptive colonization of Artemia cysts with probiotic bacteria offers an alternative delivery method of selected bacteria that gives the rearing environment a head start for proliferation of non-pathogens. -
Production, feeding and storage of diatom Chaetoceros calcitrans paste by electrolytic flocculation with reduced Pb content
Villa-Franco, Annie; de la Peña, Milagros R.; Igcasan Jr., Hermoso P.; Gamuza, Glecilda B.; Teves, Christine Marie L.; Balinas, Vicente T. (Wiley, 2021-03-02)An innovative microalgae harvesting technique was carried out under various anode/cathode (2/2, 4/4 and 6/6) configuration and at different voltage treatment (3, 6 and 10 V) to efficiently electroflocculate Chaetoceros calcitrans. This study was conducted to determine the optimal configuration of electrode units (Pb and Al) and voltage settings that could improve the quality of harvested paste in terms of nutritional value and metal contamination for its later use in aquaculture. The use of 6/6 electrodes achieved the shortest harvest time of 48 ± 1 min and the lowest Pb content (83.7 ± 0.3 ppm). In terms of voltage treatment, harvest time was inversely proportional to the voltage used. However, Pb content was significantly lowest in the paste produced using 3 V (41.78 ± 0.12 ppm), when compared to those harvested under 6 V (304.35 ± 0.79 ppm) and 10 V (343.90 ± 0.91 ppm) treatment. Likewise, Pb residues in the resulting effluent are also lowest (0.245 ± 0 ppm) with 3 V treatments. C. calcitrans paste can be resuspended ≤6 months but with a lag phase of 3–4 days for use as starter culture. A 97% reduction in Pb content of C. calcitrans paste and 77% reduction in Pb content were obtained in Artemia (7.8%) fed C. calcitrans paste.
