Última Production, disinfection and evaluation for aquaculture applications of rotifer resting eggs from Bohai Bay, P.R. of China OMA Dhert, P.; Schoeters, K.; Vermeulen, P.; Sun, J.; Gao, S.; Shang, Z.; Naihong, X.; Van Duffel, H.; Sorgeloos, P.. The dynamics of resting egg production of the rotifer <i>Brachionus plicatilis</i> originating from a wild population in the Tanggu Saltworks (P.R. China) was investigated. In the natural environment as well as in semi-controlled rearing conditions an increased resting egg production was noticed with declining food availability. Processed resting eggs had a hatching efficiency of 3x10<sup>6</sup> rotifers per gramme irrespective of their origin. Hatching started 22h after the initiation of incubation and was completed after 36h. Rotifers obtained from resting eggs could be further cultured on Culture Selco® and enriched with Super Selco®. The fatty acid profile of these rotifers were not divergent from reference rotifers... Tipo: Info:eu-repo/semantics/article Palavras-chave: Aquaculture; Resting eggs; Rotifera. Ano: 1997 URL: http://www.vliz.be/nl/open-marien-archief?module=ref&refid=2939 Influência de fatores abióticos na eclosão de ovos dormentes do rotífero Brachionus calyciflorus Pallas (Monogononta, Ploima) Zoologia Rojas,Nilton Eduardo Torres; Verani,José Roberto; Basile-Martins,Maria Amália. The factors involved in the induction of resting eggs development and hatching are poorly understood for Brachionus calyciflorus populations of South Hemisphere. The role of some abiotic factors in controlling the hatching rates of B. calyciflorus resting eggs was investigated. Determination of optimum hatching conditions would be important in developing the use of this species as food for fish larvae in aquaculture. Resting eggs were exposed to different treatments in the laboratory, and monitored for hatching over a period of five days. Optimum hatching conditions were: pH 5-9, water ionic concentrations from 220 to 880 mg.l-1 of selected salts, temperature 25 - 30ºC, photoperiod eight or more hours light per day, and light intensity equal to or greater...
