Fishing Gear to stay cool and also not get clothes ruined from blood

Hey guys - I work as a mate on a commercial fishing boat in New England.

I am in a conundrum because during the summers it is incredibly hot and we do not have a cabin so I tend to wear white clothing to dissipate the heat. I have had a number of severe sunburns from being on the water over the years.

The problem with white clothing is that all my clothes get completely ruined from the blood of the fish we are catching and cleaning. It is my job to clean the tuna to prepare it for the buyer.

Is there any type of gear that is good from the sun and also good against blood. I am planning on buying white grundens but I am thinking more for shirts. The sun shirts are great until you actually start having to work on the fish.

Thanks!
