I'm not sure it helps at all regarding co2, you'll shit it and breath it out in a matter of days... co2 is only a problem when you burn fossil fuels, because you reintroduce millions years of deposit back in the atmosphere in a very short period of time. That's why things like burning wood aren't a big deal other than localised pollution

By avoiding fishing, you stop damaging many of the carbon sink systems in the ocean, and so as a second-order effect improve the sinks we used to have.
Shitting it will not release it into the air. Maybe a small percentage, depending on it's circuit in nature. But yes, your point about the CO2 circuit stands.
Over time it would gradually remove CO2 since not all of it goes back, but stuff like this isn't even a rounding error compared to the amount of CO2 we'd need to remove.
Planting billions and billions of trees would pull a lot more, but still would only make a small dent. Greening large desert regions with large scale water and local climate engineering projects, ocean seeding, etc. would also pull more but still only make a dent.
Tell that to the anti-cow people, they will have a cow
There are countless carbon sinks within the ocean. It finds its way into the shells of creatures (calcium carbonate) and hangs around for a very long time in solid form. And lots of creatures die/defecate, that sinks to the bottom of the sea, and much of the carbon there doesn't rise back up since not all of it is consumed.
And when you're spreading seaweed over a fish farm, a good chunk of that is flowing back out into the ocean and contributing to the cycle of carbon deposits.
