  author={Nathan Huysman and Eric Krebs and Jill M. Voorhees and Michael E. Barnes},
Environmental enrichment is the inclusion of materials into hatchery rearing tanks to create more natural or complex environments. This study evaluated juvenile rainbow trout Oncorhynchus mykiss rearing with the use of a vertically-suspended array consisting of 15 rods in comparison to an established enrichment array of nine vertically-suspended rods, and unenriched controls. At the end of 116 days, there were no significant differences in gain, feed conversion ratio, total length, or…

Use of Vertically-Suspended Environmental Enrichment during Early Rainbow Trout Rearing
This study evaluated the use of vertically-suspended structure as a form of environmental enrichment during hatchery rearing of rainbow trout Oncorhynchus mykiss. This experiment was broken up into
Influence of Water Velocity and Vertically-Suspended Structures on Rainbow Trout Rearing Performance
This study evaluated the effects of two water velocities and three types of vertically-suspended environmental enrichment during the rearing of juvenile rainbow trout (Oncorhynchus mykiss; mean ± SE,
Behavioral Response of Multiple Rainbow Trout to Vertically Suspended Environmental Enrichment
Results indicate that trout location is influenced by the presence of vertically suspended environmental enrichment and that learning from prior experience with enrichment occurs.
Use of Exercise and Structure during Rainbow Trout Rearing
Fish rearing performance can be improved with the addition of either vertically-suspended aluminum angles or an exercise routine, but the combination of the two techniques may not be needed to improve rainbow trout growth.
Impacts of Different Exercise Routines on Rainbow Trout Rearing Performance
This exercise regime can be used to obtain the benefits of exercise without sacrificing rearing performance and grew similar to, and as efficiently as, the trout receiving low exercise and fed to satiation.
Investigation of dependences of the morphological composition of body and amino acid composition of trout meat proteins (Oncorhynchus mykiss) on levels of the energy value of feeds
The article studies the effect of using complete compound feeds with different energy levels on the morphological composition of the body and the amino acid composition of trout meat proteins. The
Ефективність вирощування цьоголіток райдужної форелі (Oncorhynchus mykiss) за різного вмісту лізину та метіоніну у кормах
It is proved that the reduction of lysine content to 2.7% and methionine to 0.85% in compound feed for this year trout weighing more than 10 g causes a significant (p<0.05) decrease in fish productivity, and feeding compound feeds with the above amino acid levels helps to reduce trout weight and reduce growth rate.
Enrichment in a Fish Polyculture: Does it Affect Fish Behaviour and Development of Only One Species or Both?
There was no statistical difference for the frequency of abnormal behaviours for pikeperch and sterlet between the two sets (with or without enrichment) and all the morphological and growth parameters no matter the species and the rearing modality.
Effects of Intermittent Exercise during Initial Rainbow Trout Oncorhynchus mykiss Rearing in Tanks Containing Vertically-Suspended Environmental Enrichment
Occupational enrichment is a category of environmental enrichment including exercise [5]. Fish are typically forced to exercise by increasing water velocities [9-11], which has generally been


Suspended Arrays Improve Rainbow Trout Growth during Hatchery Rearing in Circular Tanks
Weight gain and feed conversion ratio were significantly improved in fish reared in tanks containing either of the suspended structures compared to unenriched control tanks, suggesting that vertical rods or angles is recommended during rainbow trout rearing in circular tanks, although using angles may be more desirable because they require less material to construct.

These experiments are the first to indicate no benefits during the rearing of salmonids using vertically-suspended enrichment, with no significant difference in gain, feed conversion ratio, individual fish total length, or individual fish weight between the enriched and unenriched treatments in any of the three trials.
Use of Bottom Structure and Tank Cover during Rainbow Trout Rearing in Circular Tanks
Fish reared with overhead cover had a significant weight gain increase and a significant feed conversion ratio decrease compared to uncovered tanks, and the use of overhead cover is recommended to increase trout rearing performance in circular tanks.
Structural Complexity Improves the Rearing Performance of Rainbow Trout in Circular Tanks
This study examined the growth and condition of juvenile Rainbow Trout Oncorhynchus mykiss reared in nearly fully covered circular tanks containing nine vertically oriented round aluminum rods (structurally complex) compared with that of trout rearing in almost fully covered tanks with no rods (control) at two water velocities.
Vertically-Suspended Environmental Enrichment Alters the Velocity Profiles of Circular Fish Rearing Tanks
The inclusion of vertically-suspended environmental enrichment in circular tanks has produced substantial benefits during fish rearing. This study examined the tank water velocity profiles of four
Flow Patterns in Circular Rearing Tanks Containing Vertical Structure
At both of the flow rates, velocities with the rods present were still sufficient to create a vortex capable of keeping the tank self-cleaning, which may explain part of the reason for the positive effects of vertically-suspended rods on fish rearing performance.
Rearing in Enriched Hatchery Tanks Improves Dorsal Fin Quality of Juvenile Steelhead
Variation in fin length did not substantially affect the ability to achieve dominance in agonistic contests for feeding territories; fish with longer dorsal fins won approximately 57% of contests against fish with fins that were 25% shorter on average.
Vertically-Suspended Environmental Enrichment Structures Improve the Growth of Juvenile Landlocked Fall Chinook Salmon
Environmental enrichment is the addition of structures or materials to create a more natural or complex environment in otherwise stimuli-deprived hatchery rearing units to improve post-stocking survival and promote greater social dominance in hatchery-produced fish.
Social dominance, growth, and habitat use of age-0 steelhead (Oncorhynchus mykiss) grown in enriched and conventional hatchery rearing environments
Rearing steelhead in more naturalistic environments could result in hatchery fish that behave and integrate into the postrelease (natural) environment in a manner more similar to wild fish.
Effects of Rearing Density and Structural Complexity on the Pre‐ and Postrelease Performance of Atlantic Salmon
Evaluated the effects of rearing density and structural complexity on the culture and postrelease performance of age-0 Atlantic salmon Salmo salar using a 2 × 2 factorial design, and found Atlantic salmon reared at reduced density grew faster during the stream.
