A prop\u00f3sito dos excelentes artigos que o Lu\u00eds Moreira tem dedicado sobre a rela\u00e7\u00e3o de Portugal com o Mar e em particular o “De volta ao mar – Quintas Mar\u00edtimas<\/a>” relembrei-me do que li no livro Plan B 2.0<\/a> Rescuing a Planet Under Stress and a Civilization in Trouble (que pode ser lido totalmente online)<\/p>\n

Nele, e a prop\u00f3sito da aquicultura, refere alguns dados que eu n\u00e3o conhecia, nomedamente:
\n– em 2003, a produ\u00e7\u00e3o em aquicultura representava j\u00e1 32% do total de produ\u00e7\u00e3o de peixe (42.3Mton \/ 132.5Mton);
\n– entre 1993 e 2003, a produ\u00e7\u00e3o em aquicultura duplicou tendo passado de 3.2ton em 1993 para 6.7 em 2003 num percurso sempre crescente
\n– nesse mesmo periodo, a captura de peixe subiu marginalmente (4%) de 86.6ton para 90.2ton tendo, aparentemente, chegado ao seu pamatar superior nos cerca de 90ton
\n(ver outros indicadores aqui<\/a>)<\/p>\n

\"\"<\/p>\n

Em rela\u00e7\u00e3o a Portugal dados do anu\u00e1rio estatistico da regi\u00e3o norte 2007 do INE referem que em 2006, a aquicultura ainda tinha uma express\u00e3o residual com 7.9kton em aquicultura, para 160.8kton de captura, ou seja uns miseros 4% do total.<\/p>\n

Para o crescimento da produ\u00e7\u00e3o em aquicultura muito contribui a China<\/a>.
\n“China, producer of more than 20 million tons of farmed fish, which is roughly two thirds of the global total, has devoted 5 million hectares of land \u2014 much of it cropland \u2014 to fish ponds.”<\/p>\n

N\u00e3o esquecer no entanto que h\u00e1 alguns problemas que se podem levantar<\/a> com esta aposta na aquicultura.
\n“The bottom line is that the growing worldwide demand for seafood can no longer be satisfied by expanding the oceanic fish catch. If it is to be satisfied, it will be by expanding fish farming. But once fish are put in ponds or cages they have to be fed, further intensifying the pressure on land resources.”<\/p>\n

De qualquer forma, parece que tamb\u00e9m aqui temos ainda muito potencial para crescer.<\/p>\n","protected":false},"excerpt":{"rendered":"
