“…Likewise, it was demonstrated that in low densities, growth rate was higher, especially when bigger rainbow trout (98.2 ± 18.9 g and 22.5 ± 0.94 cm) were introduced in RAS in the PExPA, and under those conditions daily growth rate reached 3.6 g [6]. Similar growth rates were obtained with an initial total weight of 85.2 g, obtaining organisms with an average of 250 g in four months of culture [33]. Rainbow trout exhibits different growth rates according to fish density, type of culture system, water quality and food [8]- [13] [16].…”

“…Evaluating experimental diets with different vitamin E quantities, registered a SGR from 1.87 to 1.94 and a FCR of 1.06 to 1.12 [11]. Others authors reported a SGR from 1.4 to 1.5 and a CF of 1.6. and a SGR from 0.30 to 1.21 and FC from 1.18 to 1.52 [13] [15].Testing the effects of natural pigments in rainbow trout, were reported a SGR from 1.3 to 1.6 and a FCR with an average of 1.5 [14], and in floating cage culture were recorder a SGR of 0.07 and 3.3 and a FCR from 1.1 to 1.3 [17], Yoshitomi [18] showed values of SGR from 3.0 to 3.1, with a survival rate around 99%. Finally, in 21 small water bodies with a rainbow trout cage farming system, SGR fluctuated from 1.1 to 2.5 reaching a daily growth rate from 1.4 to 9.0 g/day.…”

“…However, the ponds water temperature was over 3˚C of the optimum value; the dissolved oxygen (DO) was controlled by different mechanisms implemented in the RAS. There is a quite amount of information on water quality of this PExPA system [6] [14] [33] [38] and it has been probed in several occasions that water quality keeps acceptable levels allowing a good growth performance of rainbow trout. In general, DO was maintained through three main processes: 1) atmosphere interchange, 2) blower air injection and 3) injection by mean of Ventury tubes.…”

The growth performance of a selected F1 rainbow trout genetically characterized as polymorphic with locus Omy207UoG (NA = 13, PIC = 0.891, H E = 0.9003) was evaluated in a recirculating aquaculture system (RAS). A set of 157 rainbow trout of 37.8 g of mean body weight and 14.6 cm mean total length per tank, were introduced in each of six fish tank of 5 m 3 connected to a recirculating aquaculture system (RAS). The trout was rearing during 317 days. Growth performance indicators and water quality were evaluated during the experiment. The genetically selected F1 rainbow trout showed a tendency towards homogeneity in growth performance along the culture period, reaching a mean total weight of 552.2 g. The length-weight relationship indicated an isometric growth (>3.0). This study presents the basis to establish a long-term marker-assisted selection program for rainbow trout culture in a subtropical region.

“…Several different mathematical models can be used to describe the relationship between color parameters and carotenoid content (Bjerkeng, ). Some studies reported linear relationships (Buttle et al., ; Baker et al., ; Ingle de la Mora et al., ), others employed non‐linear models when the carotenoid content was high (Christiansen et al., ; King, ). The reason for this is because our color perception becomes saturated asymptotically when the carotenoid content exceeds certain limits (Bjerkeng, ).…”

An 8-week feeding trial was conducted to evaluate the effects of dietary xanthophylls/ astaxanthin ratio on the growth and skin color of large yellow croaker, Larimichthys crocea. Five pigment-supplemented diets were formulated to contain 75/0, 50/25, 37.5/37.5, 25/50 and 0/75 mg kg À1 of xanthophylls/astaxanthin. The xanthophylls contain 89.31% lutein and 6.12% zeaxanthin. A diet without pigment supplementation was used as the control. The large yellow croaker juveniles (13.80 AE 0.03 g) were randomly distributed in 18 sea cages (1.0 9 1.0 9 1.5 m) at a density of 45 fish per cage. Water temperature ranged from 21 to 31°C during the feeding trial.To obtain results, the survival rate, specific growth rate, feed conversion ratio, skin redness, skin yellowness, skin lightness, skin carotenoid content and skin melanin content were measured. The results showed that the survival rate, specific growth rate and feed conversion ratio were not significantly affected by dietary treatments (P > 0.05). The ventral skin lightness was also not affected by dietary treatments (P > 0.05); however, the dorsal skin lightness of fish fed with the control diet was significantly lower than those fed with pigment-supplemented diets (P < 0.05). The lowest values of yellowness and carotenoid content both in the ventral skin and dorsal skin were found in the control group. Yellowness and carotenoid content increased with an increasing proportion of dietary xanthophylls in both the ventral and dorsal skin. Higher redness values were found in the compound pigment groups, either in the dorsal skin or ventral skin. Fish fed with the control diet showed a higher melanin content in the dorsal skin than those fed with pigment-supplemented diets, although differences were not significant (P > 0.05). Lightness and yellowness were linearly related to skin carotenoid content. Meanwhile, skin yellowness and carotenoid content were linearly related to the proportion of xanthophylls in dietary pigments.

In this study, we have investigated the effects of Porphyridium cruentum (Rodophyta) as a natural pigment source and astaxanthin and b-carotene as synthetic pigment sources on the skin colour of cichlid fish (Cichlasoma severum sp., Heckel 1840), which are generally light orange with white patches and becomes shiny orange in the reproductive phase. The fish were fed diets containing 50 mg kg -1 astaxanthin and bcarotene, and P. cruentum powder. The amount of both natural and synthetic pigment sources given as feed was 50 mg kg -1 , and the experiment was continued for 50 days. Total carotenoid content of the fish was determined spectrophotometrically at the end of the experiment. As a result, while a visible change of colour in the skin of the fish fed on the feed containing astaxanthin was observed with 0.34 ± 0.2 mg g -1 of pigment accumulation, a relatively small change of colour was observed in the skin of other fish that were fed on the feed containing P. cruentum and b-carotene with 0.22 ± 0.2 mg g -1 and 0.26 ± 0.1 mg g -1 of pigment accumulations, respectively. Therefore, it was determined that these pigment sources have an effect on the colour of cichlid fish.
