This publication describes the requirements for the use of ice (and chilled seawater) on board fishing vessels, from small insulated containers in dugout canoes, to refrigerated tanks on bigger vessels. It also gives and overview of the different ice plants and the ice produced. This publication is aimed both at fishermen who want to have more information about the technique used, and at boat owners who want to invest in the use of ice to preserve the catches, and meet the increasing demand for good quality fresh fish.
