Dietary enrichments with the arachidonic acid (ARA)-rich microalga, Parietochloris incisa, on the survival of guppy (Poecilia reticulata) fry were examined. Diets were applied via Artemia enrichment to fish from two commercial farms for 34 and 36 days of experimental period (trials 1 and 2, respectively). In trial 1, Artemia nauplii were enriched with dry biomass of whole algal cells at 0 (cont...

Ž . The effects of high dietary docosahexaenoic acid 22:6ny3, DHA and varying arachidonic Ž . acid 20:4ny6, AA were tested on growth, survival and resistance to handling stress in 5–35 day old gilthead seabream larvae. Three enrichment treatments differing in their DHArAA ratios Ž . Ž were fed to rotifers Brachionus rotundiformis and Artemia nauplii. The high DHA 35.9% . Ž . TFA enrichment trea...

the aim of this study was to evaluate the effects of enrichment of artemia with sea weed extract (padina sp.) on the survival and growth rates of post larvae of western white shrimp (litopenaeus vannamei). this investigation was conducted in the shrimp research center, bushehr, iran. the experimental design was done in three dietary treatments with three replications which were conducted in 9 w...

This study examined the feeding performance of cultured larvae of the greenback flounder Rhombosolea tapirina, using the live feed organisms, Brachionus plicatilis and Artemia sp., to determine the primary sensory modality involved in feeding, and the effect of previous exposure to prey on subsequent prey selection. The proportion of larvae that fed on rotifers in the light Ž y1 y2 . 400–700 nm...

Bacterial diseases have been reported to be the major limiting factor in shrimp production. The use of natural products such as antimicrobials has been reported as a solution to the problem. The crude extract of a red seaweed Laurencia snyderiae obtained from the Persian Gulf was evaluated for shrimp growth performance and to determine in vivo efficacy of this seaweed in the prevention of shrim...

This study was conducted to evaluate the effects of a toy on behaviour and body weight weaned pigs after mixing. Two groups (192 in total, control: without toy; treatment: with placed floor) housed pens (1.8 m × 1.4 m, 4 pigs/pen) were observed aid video technology for nine consecutive hours early (days 1 2) late 38 39) period Bodyweight at end (Mann-Whitney U-test, Z = -2.46, P 0.01) average ...
