La ciència de les pesqueries: un exemple de ciència multidisciplinària

Abstract

Al final del segle XIX es va iniciar la recerca seriosa de l’impacte de la pesca en les comunitats marines. Com era previsible, les primeres recerques van estar relacionades amb la identi!cació taxonòmica de les espècies objecte d’explotació: sardina, areng, seitó, verat, bacallà, etc. Aquesta primera etapa va tenir una durada curta, i ja en aquelles dècades es van assajar models numèrics que relacionaven les captures obtingudes amb l’esforç esmerçat a obtenir-les. Els primers models relacionaven senzillament l’esforç i la captura obtinguda. És evident que a un esforç nul correspon una captura nul·la; però, a un esforç molt elevat, pot correspondre també una captura nul·la o molt petita per esgotament del recurs. Ara, aquest model groller no ens diu res de la biologia de l’espècie explotada
