Topic: Rainbow trout- Exercise/stress and the effects it has on reproduction

In a unique study done by Arjan Palstra et. all, they discovered a unique correlation between long-distance exercise and the development of oocytes in the ovaries in Rainbow Trout. In the study, the researchers found significantly reduced ovarian development in female Rainbow Trout that were swam for 10 or 20 days when compared to those that were not exercised. The most likely cause of this decrease in ovarian development is to secure fuel for muscles, and decrease the risk of muscular atrophy, during long distance swims to reproducing grounds.

Updated Draft:

Researchers have found significantly reduced ovarian development in female rainbow trout that swam for ten to twenty days when compared to females that were not exercised [1]. The most likely cause for this decrease in ovarian development is the reallocation of fuel for muscles, which may decrease the risk of muscular atrophy during long distance migration to spawning grounds. Stressors, like crowding and noise, experienced during vitellogenesis can also lead to smaller eggs. These studies suggest there are trade-offs  between reproduction and other energy demanding activities in rainbow trout.

Where it should go: I would make a new section called “Physiology” and would add the specific info in a subsection called “Physiological Trade-offs”. I would potentially move the the section currently called “Growth and oxidative stress on mitochondria” to the new Physiology section Refernce
