- 1. Offshore training: ๐๐ฏ๐ค๐ฐ๐ณ๐ฉ๐บ๐ฏ๐ค๐ฉ๐ถ๐ด ๐จ๐ฐ๐ณ๐ฃ๐ถ๐ด๐ค๐ฉ๐ข anatomy (sampling method)
It is a video of sampling (dissection) of pink salmon (๐๐ฏ๐ค๐ฐ๐ณ๐ฉ๐บ๐ฏ๐ค๐ฉ๐ถ๐ด ๐จ๐ฐ๐ณ๐ฃ๐ถ๐ด๐ค๐ฉ๐ข) 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.

After the fish has stopped moving, we measure the fork length as the body length, and measure the weight using a balance.

Blood is collected from the base of the tail with a syringe. Later, the serum will be obtained by centrifugation. We can measure hormones, etc.
- 4. Offshore training: ๐๐ฏ๐ค๐ฐ๐ณ๐ฉ๐บ๐ฏ๐ค๐ฉ๐ถ๐ด ๐จ๐ฐ๐ณ๐ฃ๐ถ๐ด๐ค๐ฉ๐ข anatomy (Scale sampling)
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.

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.

Caution: this video contains dissection images.
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.
