Evidence of fish tanks on Roman ships

(Original article link in title) A lead pipe found on a wreck of a Roman ship has led experts to suggest that this may be the only remaining evidence of on-board fish tanks. We do know that the Romans possessed the technology necessary for such a device to have been a reality (i.e. pump and piston mechanisms). Some researchers say that the fish tanks open up all new possibilities of trade and transport of fish from where they were caught to far-off ports. It was originally thought that fish caught at sea were eaten at the nearest harbor. This may add evidence to disprove that theory.
“It would change completely our idea of the fish market in antiquity. We thought that fish must have been eaten near the harbours where the fishing boats arrived. With this system it could be transported everywhere.”
Other researchers say that the proponents of fish tanks are too quick to disregard possible fire-fighting mechanisms. Hopefully more evidence will come to light and reveal the answers to the debate.
