| We have developed a mathematical model that can set the amount of biomass in a given fishery, based on its biological behavior, and its respective sustainable yield curves. In this way, in line with the evidence of different catches in various fisheries' registered annuities, the model also allows the system to determine whether the fishery constitutes a form of sustainable fishery to allow subsistence fishing or lead to its collapse or disappearance. The model has been applied to the case of the white shrimp fishing grounds of Guinea Bissau in adapting to historical catch data provided by FAO and the Guinean authorities, thus obtaining results that fit perfectly with previous records, and allow it to assess the volume of biomass in a figure of about 27,500 tons. Their exploitation, according to current conditions, by extrapolating them to a future of more than one hundred years, can be regarded as entirely sustainable | |
