“…Fish nutrition plays a role in freshness and fillet appearance, important traits when defining farmed fish quality (Lie 2001), and therefore the fillet hue was evaluated in the current study. Although it is generally considered as a good source of carotenoid pigments for salmonids (Sanderson & Jolly 1994; Coral et al. 1998; Whyte & Sherry 2001), our experiment demonstrated that increasing levels of dietary yeast did not significantly affect flesh hue values of pacu, being very similar to those values observed in flesh of fish fed fishmeal‐based diet.…”

A feeding-and-digestibility trials were carried out to evaluate the efficacy of replacing fishmeal with brewers yeast Saccharomyces cerevisiae in diets of pacu, Piaractus mesopotamicus, juveniles. The feeding trial was conducted during 54 days with 450 fish (26.6 ± 1.7 g) testing six isonitrogenous (270 g kg )1 crude protein) and isoenergetic (19 MJ kg )1 crude energy) diets, with increasing yeast level to replace 0 (control), 30, 35, 50, 70 or 100% of dietary fishmeal. Growth performance and feed utilization increased with increasing dietary yeast level until 50% fishmeal replacement. Protein retention efficiency was higher in fish fed 35 and 50%. Protein digestibility and the fillet hue (the red/green chromaticity) were not significantly different among all treatments. Nitrogen gains were significantly improved in fish fed 35% replacement diet compared to fish fed the control diet. The retentions of indispensable amino acids tended to increase with increasing dietary yeast levels, with maximum retention at 35-50%. On the basis of our results, replacing 50% fishmeal by yeast in pacu diets successfully improved feed efficiency and growth performance, and reduced nitrogen losses, thereby reducing the nitrogen outputs from fish farms.

“…Recently, most of promising alternatives to synthetic Asx for salmonids coloration are Haematococcus algae [8,9], Phaffia rhodozyma [10], Longistilla, Pleuroncodes planipes [11] and Chlorella vulgaris [12]. In addition, red pepper (Capsicum annum) and marigold flower (Tagetes erecta), which are abundant and rich in carotenoid pigments, could be considered alternative sources [13].…”

This study was performed to investigate the effects of marine bacteria (Paracoccus sp.) and synthetic astaxanthin (Asx) as Asx sources on coloration (skin and muscle) of rainbow trout (Onchorhynchus mykiss). In the 12-week trial duplicate groups of 30 fish (28.1 ± 0.3g) were fed one of the four experimental diets. Three experimental diets contained 30 mg Asx/kg diet of synthetic Asx, marine bacteria or combined synthetic Asx and marine bacteria. One diet was served as a control diet. The fish fed diet supplemented both marine bacteria and synthetic Asx provided the highest total carotenoids and Asx content in the skin and muscle.

“…The source and concentration of carotenoids play an important role in pigmentation of ¢sh (Gouveia & Rema 2005). Various synthetic carotenoids, such as b-carotene (BC), astaxanthin (AX) (Choubert & Storebakken 1989;Storebakken & No 1992), as well as natural sources (Coral, Huberman, De la Lanza & Monroy-Ruiz 1998;Chien & Shiau 2005;Kalinowski, Robaina, Fernandez-Palacios, Schuchardt & Izquierdo 2005) have been used as dietary supplements to enhance the pigmentation of food ornamental ¢sh (Gouveia, Rema, Pereira & Empis 2003). E⁄ciency in pigmentation from the above sources can be attributed to species of target animal, type, composition, and concentration of the pigments contained, digestibility of the material itself, and possibly the presence of cofactors in the material involved in absorption and deposition (Torrissen, Hardy & Shearer 1989;Storebakken & No 1992;Wang, Chien & Pan 2006).…”

Dietary carotenoids of various types and concentration can affect the pigmentation efficiency in an ornamental fish red devil, Cichlasoma citrinellum. Astaxanthin (AX) containing alga Haematococcus pluvialis, a synthetic AX, and a synthetic β‐carotene (BC) were supplemented in formulated diets at two concentrations, 80 and 160 mg kg−1, resulting in six pigmented diets. Formulated diet without carotenoids supplementation served as a control. These diets were fed to the fish, for 8 weeks. Astaxanthin dominated in body carotenoids deposition. Dietary BC hardly had contribution to body AX. Control fish had much lower AX content in skin, fin and muscle than fish fed pigmented diets, but had equal AX content in liver, intestine and gonad as those fish. Dietary synthetic AX had equal efficiency in depositing AX in skin and fin as natural AX but higher efficiency in gonad than natural AX. Fish fed AX supplemented at 160 mg kg−1, either natural or synthetic AX, had higher AX content in skin than fish at 80 mg kg−1 but had equal AX content in fin as fish at 80 mg kg−1. Disregarding the treatment effects, the overall average AX content in tissue in descending order was gonad>fin≧(intestine=skin)>liver>muscle.
