It is a video of sampling (dissection) of pink salmon (Oncorhynchus gorbuscha) in the offshore training 1 conducted on the training ship Oshoro-maru in the western part of the North Pacific Ocean. Living individuals are hand-fished for microscopic observation and physiological analysis. First, immobilize with carbonated water.
2.Offshore training: Oncorhynchus gorbuscha anatomy (Fish body measurement)
After the fish has stopped moving, we measure the fork length as the body length, and measure the weight using a balance.
We collect scales that show age and growth history. The scale site is important on board. It also describes the characteristics of the external morphology of immature pink salmon.
5. Offshore training: Oncorhynchus gorbuscha anatomy (Head Dissection) Caution: this video contains dissection images.
The head is dissected and the nose (olfactory bulb), each parts of brain, otoliths, pituitary gland, etc. are observed.
The abdomen is opened and observe the heart, the liver, the digestive tract, the testes, the swim bladders, and kidneys. Although the gills are part of the head, we also observe them.
