Resumen del producto

The aquaculture industry employs various strategies to get their inputs, such as obtaining juvenile organisms from wild populations for on-growing in controlled conditions. This type of aquaculture is known as capture-based aquaculture (CBA). The bluefin tunas are the most iconic species produced under this scheme. The Mexican aquaculture tuna production is based exclusively on the Pacific bluefin tuna (PFT), which represents 1.8% of the volume of domestic tuna production but 14% of its value. A bio-economic model of the PFT production was parameterized to understand this production strategy and to assist the decision making. The model considers the uncertainty inherent of the CBA (v. gr., seed weight, the initial number of organisms and fish stocking schedule). The model was parameterized using the production records of 47 pens located in Bajo Soledad and Puerto Escondido, Baja California, Mexico during three production cycles (2008-2009; 2009-2010; 2012-2013), as well from interviews with experts associated with the industry. The results show that the profitability of the operation is related to changes in the SST, as this affects the mortality and efficiency in food consumption. Bajo Soledad presents the best Key Performance Indicators. The adverse effects of SST can be mitigated when stocking the pens early in the season and trying to capture bigger PFT juveniles.
