Evaluation of growth and survival rate of Artemia parthenogenetica feed with micro algae (Isochrysisand Chlorella vulgaris)and bakery yeast(Saccharomyces cerevisiae)

International journal of the bioflux society 01/2011; 4:463-468.

ABSTRACT This study was done to evaluate growth and survival rate of Maharloo lake artemia (Artemia
parthenogenetica) (Bowen & Sterling, 1978) which feed with two species of microalgae (Isochrysis galbana and Chlorella vulgaris) and bakery yeast (Saccharomyces cerevisiae) with different nutritious ingredients for 15 days. We evaluated them in 3rd, 7th, 11th and 15th days of cultivation period for 4 times. This experiment was done in completely randomized design with 4 treatments (3 treatments and 1 control) and each treatment has 3 replicates. Artemia parthenogenetica nauplii were feed with three different types of food that includes Isochrysis galbana microalgae (T1), Chlorella vulgaris (T2) and Saccharomyces cerevisiae yeast (T4). Control had feed with blend of these three matters. After 15 days the highest survival rate was observed in control (84.00) and the lowest one was related to the T4 (59.58) which feed with Saccharomyces cerevisiae yeast (p<0.05). The highest growth rate was observed in T4, T3, followed by T1 and T2 respectively. Achievement results showed significant differences between control and other treatments (p<0.05). This study proved that treatments which feed with blend of two micro algae's species and bakery yeast have higher survival ability than the other treatments.

    ABSTRACT: Nauplii of the brine shrimp Artemia franciscana were enriched with the antibacterial drug sarafloxacin hydrochloride to determine if levels effective against four pathogenetic strains of Vibrio spp. would accumulate in brine shrimp. Three vibrio strains were Vibrio anguillarum ; the fourth was V. vulnificus . Concentrations of sarafloxacin ranging from 1 to 40% (weight: volume) were incorporated into the oil phase of Super Selco brine shrimp diets. Enriched nauplii and controls were sampled at 2h interval for 24h. Antibiotic sensitivity testing was evaluated with a modification of the Kirby-Bauer disk diffusion method. A microbiological assay with Escherichia coli was used to determine the concentration of sarafloxacin per sample of nauplii. The results indicate that sarafloxacin is rapidly taken up by larval brine shrimp and can be detected at 2h of enrichment by microbiological assay. The efficacy of sarafloxacin appears to depend on the strain of pathogen present.

    ABSTRACT: Studies were carried out to establish the feasibility of incorporating bacteria with the ability to produce inhibitory substances (BPI) into axenic cultures of Isochrysis galbana with the object of using this microalga as a vector for transmitting BPI into cultures of larval bivalves as antagonists of pathogenic bacteria in these cultures. As a first step, the ability of seven strains of BPI to grow in extracellular products of I. galbana was evaluated, with positive results with four of these (334, C33, 11 and 77). Subsequently, the effect of the addition of these strains on the growth of I. galbana was evaluated. Comparison of growth rates of I. galbana with and without the addition of BPI showed no significant differences (P >  0.05). A stable and persistent inhibitory capacity of strain C33 on the pathogen Vibrio anguillarum was also observed. Finally, studies were made on the ingestion of BPI by larvae of Argopecten purpuratus (Lamarck 1819). Results demonstrated a significant ingestion of strain 11 (P >  0.05), when it was inoculated directly into the water, and bacterium C33, when delivered in conjunction with the microalga. Upon evaluating incorporation and maintenance of BPI strains 11 and C33 after 5 days of larval culture, we observed the major presence of strain C33 (3 ×  102 cfu/larva) compared with strain 11 (90 cfu/larva). The results obtained suggested that it was feasible to use microalgal cultures as vectors for the introduction of bacterial antagonists to bacterial pathogens in molluscan larval culture.

    ABSTRACT: Artemia franciscana was grown on Isochrysis galbana Green (clone T. Iso) at saturated food concentrations (13 to 20 mg C l−1) for 11 d at 26 to 28 °C, and 34 ppt salinity. Three groups of brine shrimp were used in the feeding experiments: metanauplius III and IV (Group 1), post-metanauplius II and III (Group 2) and post-metanauplius VIII (Group 3), corresponding to 4-, 7- and 11-d-old animals, respectively. The ingestion rate, clearance rate and carbon balance were estimated for these stages at different concentrations of 14C-labeled I. galbana ranging from 0.05 to 30 mg C l−1. The handling time of algae was determined for all three groups. The ingestion rate (I, ng C ind−1 h−1) increased as a function of animal size and food concentration. In all three groups, the ingestion rate increased to a maximum level (I max) and remained constant at food concentrations ≥10 mg C l−1 (saturated food concentrations). The clearance rate (CR, μl ind−1 h−1) increased with increasing food concentration up to a maximum rate (CR max), after which it decreased for even higher food concentrations. The functional response of A. franciscana was most consistent with Holling's Type 3 functional response curve (sigmoidal model), which for the two oldest groups (Group 2 and 3) differed significantly from a Type 2 response (p < 0.05). The gut passage time for the three groups of A. franciscana, feeding on saturated food concentration (20 mg C l−1), varied between 24 and 29 min. As the nauplii developed to pre-adult stage the handling time of the algae increased as a function of animal size. The assimilation rate (ng C ind−1 h−1) in the youngest stages (Group 1 and 2) increased with increasing food concentrations, reaching a maximum level close to 10 mg C l−1. At higher food concentrations the assimilation rate decreased, and the proportions of defecated carbon increased, reaching 60 to 68% in the post-metanauplius stages (Group 3). The assimilation efficiency (%) was high at the lowest food concentrations in all three groups (89 to 64%). At higher concentrations, the assimilation efficiency decreased, reaching 56 to 38% at the highest concentrations.
