“…4 term climatic models of variability (Chavez et al, 2003;Rocha et al, 2013). In most marine systems and for many fish populations, relationships between environment and recruitment have been proposed, but they have often been contested or have failed when retested with new and longer sets of observations (see Myers, 1998).…”

Sardine fisheries are of great importance to Portugal and are data-rich and of primary concern to fisheries managers. In Portugal, sub-stocks of Sardine pilchardus (sardine) are found in different regions:the Northwest (IXaCN), Southwest (IXaCS) and the South coast (IXaS-Algarve). Each of these sardine sub-stocks is affected differently by a unique set of climate and ocean conditions, mainly during larval development and recruitment, which will consequently affect sardine fisheries in the short term. Taking this hypothesis into consideration we examined the effects of hydrographic (river discharge), sea surface temperature, wind driven phenomena, upwelling, and wind magnitude were negatively related with LPUE, revealing that environmental effects match with the regional peak in spawning time. Overall, results suggest that management of small, short-lived pelagic species, such as sardine quotas/sustainable yields, should be adapted to a regional scale because of regional environmental variability.

KeywordsThis paper develops two fisheries models in order to estimate the effect of global warming (GW) on firm value. GW is defined as an increase in the average temperature of the Earth's surface as a result of CO 2 emissions. It is assumed that (i) GW exists, and (ii) higher temperatures negatively affect biomass. The literature on biology and GW supporting these two crucial assumptions is reviewed. The main argument presented is that temperature increase has two effects on biomass, both of which have an impact on firm value. First, higher temperatures cause biomass to oscillate. To measure the effect of biomass oscillation on firm value the model in [1] is modified to include water temperature as a variable. The results indicate that a 1 to 20% variation in biomass causes firm value to fall from 6 to 44%, respectively. Second, higher temperatures reduce biomass, and a modification of the model in [2] reveals that an increase in temperature anomaly between +1 and +8°C causes fishing firm value to decrease by 8 to 10%.JEL Classification: Q21, Q22, Q54, Q56, Q57.

“…With respect to the US mollusk fishery, Cooley and Doney (2009) estimate a net present value of ex-vessel revenue losses (discount rate = 4%) of between US$0.32 billion and US$1.36 billion by 2060 due to ocean acidification. Although the Iberian-Atlantic sardine fishery will not be affected in the short run (Rocha et al 2013), a drop of about 1.3% in annual profits is predicted by 2030 (Garza et al 2010). Finally, for both Greenland and Iceland, a positive impact of CC on both fish stocks and gross national product is likely to occur over the next 50 years (Arnason 2007).…”

“…sardines and anchovies) in Asian countries of between US$1 million (in Thailand) and US$700 million (in the Philippines). In the same vein, the Iberian Atlantic sardine fishery would lose between 0.36% and 1.27% of its annual profits (discount rate = 5%) by 2030 (Garza et al 2010;Rocha et al 2013). Therefore, it would be difficult either to recommend or to forecast an influx of financial capital into sardine fisheries, due to the associated high degree of variability and uncertainty.…”

This paper has a twofold objective: First, to estimate the changes in landings value by 2030 for two Mexican coastal fisheries, specifically shrimp and sardine fisheries, as a consequence of climate change; and second, to discuss the implications of such impacts for food security. A dynamic panel model was used for the Mexican fisheries sector, with data from 1990 through 2009. The results suggest that shrimp production will be negatively affected, while in contrast, the sardine fishery is expected to benefit from the increase in temperature. Most losses/gains would be observed in the NW Mexican Pacific, where the fishing sector has an important role in the local economy, representing a risk to food security in both direct and indirect ways.Published in Special Issue Food Security and Climate Change JEL C23 Q22 Q51 Q54
