Evaluation of the distribution of adipose tissues in fish using magnetic resonance imaging (MRI)

摘要: Abstract The accumulation of excess fat in fish would impair health and has been a serious problem cultured fishes. Adipose tissues are specific for deposit many species, therefore the knowledge anatomic distribution total mass adipose is basic premise to study mechanism economic However, this issue not well documented. To investigate morphology fishes, T1-weighted magnetic resonance imaging (MRI) technique was developed scan grass carp, turbot, tilapia, pompano large yellow croaker. Three-dimensional (3-D) images that quantitatively integrated volumes these were constructed first time. From 2-D 3-D MRI images, we identified two patterns tissue fish: visceral dominant (grass croaker) subcutaneous (turbot). assessed by highly consistent with those obtained traditional dissection. In fasting experiment on signal mesenteric successfully distinguished between before after 28-d starvation. Although our limitations measuring lipid organs specifically dedicated storage, e.g., liver, muscle intestine, method will help researchers gain insights into distribution, size, volume shape intact live fish. This could be powerful tool future studies metabolism. Statement relevance aquaculture aquaculture, fish, which mainly sourced from unbalanced diets or feeding strategy, Our present work investigated content five fishes different feed habits farming environments using technique. Through work, described shape, We also an ideal scanning largely expends application nutrient physiological aquatic animals. Because widely accepted closely related nutrition status most farmed animals, including close aquaculture.
