Sasha Saugh, I recently did a mini-project on environmental enrichment's (EE) effect on crayfish aggression. As you expressed, this field appears to be dominated by fishes. I only have 2 primary sources in my biblio that may interest you:

Baird et al. 2006 https://doi.org/10.1111/j.1365-2109.2006.01575.x

Corkum and Cronin 2004 https://doi.org/10.1007/s10164-003-0095-x

Both used freshwater crayfishes as models. EE comprised simple addition of objects. In general, increased habitat complexity due to EE decreases agonistic interactions, while Corkum and Cronin also reported increased feeding rates.

Hope this helps.

Thanks Vhey, will look into these 2 references.

Yes, there have been a number of studies published on energy metabolism (EE) in crustaceans, including shrimp. Here are a few articles that you may find helpful:

In the study, researchers may have used various techniques such as respirometry, enzyme activity assays, or biochemical analysis to quantify the metabolic rates and energy utilization of the green crabs at different temperatures and sizes. They may have also performed controlled experiments to observe the effect of temperature on the metabolic rate of the crabs, and to determine the relationship between size and metabolic rate.

The findings of this study could help to improve our understanding of the energy metabolism of crustaceans, and how changes in environmental conditions such as temperature can impact their survival and growth. Additionally, this research could also have practical implications for the management and conservation of crustacean populations, as well as for the aquaculture industry.

Here is a list of some of the published articles on environmental enrichment for shrimp and crustaceans:

This is just a sample of the many published articles on environmental enrichment for shrimp and crustaceans. You can find more articles by searching academic databases such as PubMed, Google Scholar, and Scopus using keywords related to environmental enrichment and shrimp or crustaceans.

I hope this will help.

Harry Kenn Tolentino Dela Rosa, your list is impressive. But I can't seem to find any of these titles either on Google Scholar, Scopus, or PubMed. I wonder if you could provide a link, DOI, or at least the journal details? Especially #7 by Smith et al. 2015, as I'm interested in EE's effect on redclaw crayfish.

Thanks!
