“…). Sand substrates, which allows burying, also reduces respiration rate and resting metabolic rate in Dover sole, indicating that sandy substrates provide less stressful environments (Peyraud and Labat ; Howell and Canario ). Substrates can also eliminate the occurrence of ambicolouration (pigmented blind sides) in flatfishes (Rabben and Huse ; Kang and Kim , ), which can increase the appeal of cultured flatfish to customers in fish markets.…”

“…This could be beneficial if the fish are destined for release as stock enhancement, but also within the hatchery system if the fish are cannibalistic, like for example juvenile olive flounder Paralichthys olivaceus (Paralichthyidae) (Dou et al 2000). Sand substrates, which allows burying, also reduces respiration rate and resting metabolic rate in Dover sole, indicating that sandy substrates provide less stressful environments (Peyraud and Labat 1962;Howell and Canario 1987).

Environmental enrichment for fish in captive environments: effects of physical structures and substrates

Structural environmental enrichment, that is, a deliberate addition of physical complexity to the rearing environment, is sometimes utilized to reduce the expression of the undesirable traits that fish develop in captivity. Increasing demands and regulations regarding usage of enrichment to promote fish welfare also make investigations on the effects of enrichment important. Here, we sythesize the current state‐of‐the‐art knowledge about the effects of structural environmental enrichment for fish in captive environments. We find that enrichment can affect several aspects of the biology of captive fish, for example, aggression, stress, energy expenditure, injury and disease susceptibility. Importantly, these effects are often varying in direction and magnitude, and it is clear that just addition of structure is not a solution to all problems in fish rearing. Each species and life stage needs special consideration with respect to its natural history and preferences. A multitude of different enrichment types has been investigated and many studies investigate several enrichment components at the same time, making comparisons among studies difficult. To the present date, the majority of efforts have been directed to investigate salmonid fish in stock‐fish hatcheries and cichlids from a basic research perspective. Some contexts are under‐studied with respect to environmental enrichment, for instance effects on results in basic research and welfare effects in display aquaria. There are many research opportunities left within this field. However, future studies could utilize experimental designs which make it possible to discriminate between effects of different environmental manipulations to a higher degree than what has been performed to this date.

“…Predation risk is likely to be lower in the dark and fish increase their activity and hence decrease their selectivity under these conditions. Finally, selection of areas of the sea bed composed of sediments in which fish can bury may provide them with the opportunity to conserve energy by reducing their metabolic rate (Peyraud & Labat, 1962;Howell & Canario, 1987) or by sheltering from strong currents (Arnold & Weihs, 1978).…”

In the laboratory juvenile plaice Pleuronectes platessa (13-114 mm) were consistently found on the finest of four sediments after 24 h both in the light and the dark. Preference when assessed both by the fish's final position and by the amount of time it spent on each sediment agreed on 72% of occasions. Size did not affect preference, which was determined principally by a fish's ability to bury in a sediment. Burial reduces activity and thereby increases the time that fish spend on sediments in which they can bury. Activity level, which is dependent on light intensity and endogenous factors, therefore determines the degree of selectivity shown. Swimming duration and resting by the largest fish (71-114 mm) did not differ among sediments. Field experiments produced results similar to those obtained in the laboratory. 2000 The Fisheries Society of the British Isles

“…For example, Burke (1991) found that juvenile summer flounder Paralichthys dentatus in the laboratory preferred coarsergrained sand over finer-grained mud, even if food was available only in less-preferred sediments. Energetics studies have shown that the metabolic rates of flatfishes can increase significantly when the fish are forced to bury in sediments with suboptimal grain sizes or do not have access to sediments at all (Peyraud & Labat 1962, Hotvell & Canario 1987. Two other western Pacific flatfish species have also shown a preference for sediment types in which they could most easily bury (Tanda 1990).…”
