“…On the other hand, in the case of gilthead seabream Sparus aura, red light significantly increases brain dopaminergic activity, while a tendency towards reduced growth is also observed. Also, some other studies demonstrated that there are no significant differences in growth performance when comparing different environmental colors such as on Seahorses Hippocampus abdominal [44], on scaled carp Cyprinus carpio L. [45] and on Atlantic salmon Salmo salar L [46]. Nevertheless, in a study to evaluate the effect of tank wall color and light level, treatments affect the growth and survival of Eurasian perch larvae Perca fluviatilis L. [42].…”

Four light colors (red, white, green and blue) were tested to evaluate their effects on both body color enhancement and growth performance of Florida red tilapia (Oreochromis mosambicus × O. hornorum). Fish were stocked in 12 fiberglass tanks, (each of 2 m3 water volume), at a stocking rate of 100 fish per tank with average initial weight of 2.66 g/fish, three replicates for each treatment. Fish were fed on a commercial diet containing 25% protein, two meals per day with a daily feeding rate of 7% in the first two weeks, then reduced to 5% until the end of the experimental period (6 weeks). The results of this study reveals that there are no significant differences (p>0.05) in growth performance indexes between treatments. However, fish exposed to red color showed highest growth values. With the same trend, results of survival percent and condition factor showed no significant differences between treatments. Significant differences (p≤0.05) are observed in the whole body chemical composition between treatments. Fingerlings that are exposed to blue color has the highest value of dry matter content, while, the lowest value is observed in fingerlings exposed to red color. Feed utilization (FI, FCR and PER) do not significantly affect the lighting color, while protein and energy utilization (PPV and EU) are significantly affected. Concerning the red color accumulated in the fish body, the fingerlings which are exposed to the blue color achieved the best β-carotene value (211.25 IU/100 g fish) with highly significant differences compared with other treatments. The content of β-carotene in blue color treatment is 8, 9, and 16 folds comparing with green, white, and red colors, respectively. Also, Red tilapia fish with black spots in the blue treatment were 12%, compared with 29% in green, 56% in white and 52% in red colors.It could be concluded that cultivating Red tilapia in a full saline well water using the artificial blue color will significantly improve not only the pigmentation of Red tilapia, the quality of fish in terms of the content of dry matter, but also the protein and the energy utilization of the consumed feed.

“…Therefore, the tank color could have an important influence on fish productive performances, fact observed until now, in studies on Eurasian perch larvae (Tamazouzt et al, 2000;Jentoft et al, 2006), yellow perch (Hinshaw, 1985), striped bass (MartinRobichaud and Peterson, 1998), pot-bellied seahorses (Martinez-Cardenas and Purser, 2007), grouper (Duray et al, 1996), carp's juveniles (Papoutsoglou et al, 2000) and barramundi (Ullmann et al, 2011). In addition, some previous studies affirmed that tank color can contribute significantly to fish stress level (Rotllant et al, 2003;Papoutsoglou et al, 2005).…”

A study on Sander lucioperca age classes to assess preference for background color was imagined. Two groups: G1 (92 days old, average weight: 6.2 ±1.6 g) and G2 (461 days and 101.7 ±27.1 g), were continuously observed for 24 hours after one day of acclimation, using 90 fish / group (30 fish / replication / 24 hours), their behavior being recorded with cam-recorders. For the study, the walls and bottom of a rectangular research tank were colored equally in: grey, light and dark blue and green. During the study, were made 216 observations / group (72 observations / replication) and were statistically analyzed using Duncan test, with a confidence level of P˂ 0.05 or lower. Results revealed that a significant number from G1 was located on the green space, in order, preferred background color being: green, grey, dark and light blue. The G2 group expressed also high affinity for the green color (P< 0.001) concluding that, green background can give a safety feeling to the pikeperch, thus, rearing or transport of pikeperch categories in green tanks could have the benefit of stress decreasing and added benefit for this fish species in the aim of advancing the Recirculating Aquaculture Systems.

“…Survival rates reported in H. abdominalis range from approximately 21% (Woods 2000a ) to 80% over a 2 -month period (Woods 2000b ) and 67 -87% over a 6 -week period (Martinez -Cardenas & Purser 2007 ). Similarly, reported survival in H. reidi ranged from 10 -35% at 21 days after hatching (Olivotto et al .…”

“…The difference could in part be due to the type of enrichment used for the prey ( Artemia ). Woods (2000a) used a microalgae -based enrichment that would have resulted in the Artemia gut being darker coloured than in the study by Martinez -Cardenas & Purser (2007) .…”

“…2006 ). In contrast, the temperate seahorse species, H. abdominalis , cultured at approximately 16 -17.5 ° C achieved a standard length of 36 -43.04 mm at 56 days of age (Woods 2000a ;Martinez -Cardenas & Purser 2007 ). Similarly the tropical species, H. trimaculatus , reached 119.9 mm in SL in 26 weeks compared to H. abdominalis, which reached 110.7 mm in 52 weeks (Woods 2000b ;Murugan et al .…”
