<br/><br/> The Visayan Sea has always been one of the most productive fishing grounds in the country. For the 10-year period from 1963 to 1973, there was a general increase in the production of sardines, herring and mackerels as shown in Table 1. This fishing area has been intensively fished by commercial fishing boats such as purse seiners, basnigans and trawlers.
