Growth, metabolism, and dissolved oxygen tolerance of juvenile burbot

Ben Vaage et al.

Summary: The burbot is being considered as a potential aquaculture species in North America due to its palatability and ability to be grown in areas that support rainbow trout culture. The study found that juvenile burbot can tolerate dissolved oxygen concentrations down to 5.0 mg/L and recommends rearing them at concentrations above 7.0 mg/L for optimal growth.

Optimization of cold-shock conditions for the induction of triploidy in the Pacific bluefin tuna, Thunnus orientalis (Temminck et Schlegel)

Takao Hayashida et al.

Summary: This study investigated the optimal cold-shock conditions for inducing triploidy in Pacific bluefin tuna, finding that starting the treatment 5 minutes after fertilization at 5 degrees C for 15 minutes resulted in high triploidization rates. This method could potentially help address the issue of muscle fat content reduction during sexual maturation in aquaculture-produced Thunnus orientalis.

Effects of Temperature Fluctuation on Burbot Embryos: Implications of Hydropower and Climate Change

Neil K. Ashton et al.

Summary: Research shows that Burbot embryos are sensitive to temperature changes between 4.0°C and 5.5°C, with faster rates of warming causing greater harm. Family effects and incubation temperature influence deformity and survival of protolarvae. It is recommended that hydropower operations avoid thermopeaking during winter spawning of Burbot and maintain water temperatures below 3°C for at least the first two weeks.
