1. Suppose that you take your boat offshore for a day of deep-sea fishing. You drop anchor at a supposed ‘hot spot’ and you notice that the boat’s depth finder is indicating a water depth of 75 meters. You lower your baited hook to the bottom and quickly hook something BIG. After a brief fight, you land a beautiful, 60-pound red snapper (a physoclist) that had a total body volume of 150 liters before you hooked it. Unfortunately, you have already caught your legal limit of red snappers for the day and must therefore release this one. Assuming that this snapper was neutrally buoyant when it bit your hook (and that its swim bladder did not rupture as you reeled it to the surface), what would the volume of its swim bladder be when you place it back into the water?

2. Given your knowledge of the compensation ability of the oval region of the red snapper’s swim bladder, how long would the fish float at the surface before the oval could restore neutral buoyancy?

3. If you were a red blood cell that has just delivered your oxygen to the caudal swimming musculature of a mako shark, what route through the circulatory system could you take to eventually reach the mako’s swim bladder. Please diagram your route and label each of the vessels that you pass through.

The swim bladder is more or less an oval, soft-walled pouch located in the abdominal cavity, just below the spinal column. Its shape varies greatly, but the volume is constant between species, most often around 5% of body.

Day of deep-sea fishing

1. The volume of your swim bladder when you put it back in the water would be 7.5 liters.

2. The time the fish would float on the surface before the oval could restore neutral buoyancy would be a few seconds.

3. If I were a red blood cell that has just delivered its oxygen to the tail musculature of a mako shark, the route through the circulatory system to eventually reach the mako's swim bladder would be the venous route, like other fish, they have a heart with two chambers, an atrium and a ventricle, and closed circulation.

With this information, we can conclude that the volume of her swim bladder when she was put back in the water would be 7.5 liters.
