“…In summary, fishing costs structure and cost levels obtained in this study showed to be consistent with partial information provided in studies for the Santa Catarina region or others like Alves et al (2009), Gasalla et al (2010, Pio et al (2012), Wahrlich et al (2004) and Piniella et al (2007).…”

“…According to Sumaila et al (2008) fuel is a substantial component in the cost of fisheries and the proportion varies with each type of fishing, ranging from 60% of the costs as in commercial fishing in Hong Kong. Results for this study showed that Fuel & lubricant ranged from 52% to 57% of the vessels' Running costs what is consistent with the 23% of the total operating costs reported for the bottom gillnet fishery of São Paulo State (Gasalla et al, 2010) and with previous estimations that fuel represents between 10 and 60% of the total cost of the fishing activity in Brazil (Haimovici et al, 2006).…”

“…The determination of fishing cost structures and estimation of fishing costs levels are important information to determine in turn the economic and financial performance of the fishing vessels operating the fisheries and this in turn is an important information for fisheries management purposes (Gasalla et al, 2010). Even though results on NPV, IRR and PI for the average vessel in the three fisheries analyzed showed positive levels, the profitability of the business is low having an IRR lower than 20% and a PI lower than 2, considering a 10% discount rate.…”

“…Possible reasons for these include the lack of regulations requiring fishermen to provide this kind of information not only in Brazil but, also in most countries of the world (Gasalla et al, 2010).…”

“…In spite of the extent of the work done by Tietze et al (2005) on the economic performance and fishing efficiency of marine capture fisheries, at a global scale, data on fishing costs and cost structure are poorly documented, and they vary according to the type of fishery, vessel and fishing gear employed (Lam et al, 2011). In such cases, i.e., parametrization models, economic parameters were based only on previous empirical approximations (Gasalla et al, 2010). When costs and revenues are known, a series of economic and social analysis can be performed, subsidizing valuable information for developing a more realistic fisheries management (Dreyfus-León & Manzo-Monroy, 1993;Lucena & O´Brien, 2005;Dudley, 2008;Lam et al, 2011).…”

ABSTRACT. This cost-benefit analysis of three industrial bottom gillnet fisheries that operated in SE/S Brazil during 2009, had a double purpose: to determine the economic and financial performance of the average gillnet vessel in the coastal whitemouth croaker (Micropogonias furnieri), the gulf hake (Urophycis mystacea) and monkfish (Lophius gastrophysus) fisheries and to determine the expected effects of applying fishing gear regulation (MPA/MMA Nº12/2012) on the performance of the whitemouth croaker fishing fleet. Crucial to this cost-benefit analysis was to collect data through interviews to vessel owners on these fishing fleets cost structures and their fishing costs levels. Three economic and financial performance indicators were used to assess the condition of these fishing fleets: Net Present Value (NPV), Internal Rate of Return (IRR) and Profitability Index (PI). Results showed different costs levels between fishing fleets but, similar relative importance of cost components across fleets: with running costs being the highest, followed by vessel and labor costs in order of importance, except in the gulf hake fishing fleet. Results from the economic and financial performance assessment showed that these three fishing fleets were in a fragile economic and financial condition, all having IRRs lower that 20% and PIs of 1.7 or lower, too low for a high risk activity like fisheries. This problem been more acute in the whitemouth croaker fishing fleet with the lowest IRR (12.11%) and PI (1.2). Potential effects of applying the fishing regulation showed marginal improvements in the fragile condition of the whitemouth croaker fishing fleet.

El análisis de costo-beneficio de las tres pesquerías industriales de enmalle de fondo que operaron en el SE/S Brasil durante 2009 tuvo un doble propósito: determinar el desempeño económico y financiero de una embarcación promedio que opera con enmalle en las pesquerías de corvina (Micropogonias furnieri), brótula (Urophycis mystacea) y rape (Lophius gastrophysus) y establecer los efectos que se pueden esperar al aplicar la regulación al arte de pesca (MPA/MMA Nº12/2012) en el desempeño de la flota que pesca la corvina. Crucial para este análisis de costo-beneficio fue la recolección de información mediante entrevistas a dueños de embarcaciones sobre las estructuras y los niveles de costos en la pesca. Tres indicadores de desempeño económico y financiero fueron utilizados para evaluar la condición en que se encuentran estas flotas pesqueras: Valor Presente Neto (VPN), Tasa Interna de Retorno (TIR) e Índice de Rentabilidad (IR). Los resultados mostraron diferentes niveles de costos entre las flotas pesqueras. Sin embargo, presentan similar importancia relativa los componentes de costos entre flotas: los costos corrientes...

In the early 1990s, ecological and fishery data from the Gulf of Nicoya (Pacific Ocean) were holistically analyzed, and a trophic model was constructed using the Ecopath modeling approach. The results indicated that this tropical estuary, which is a Costa Rican fishery hot spot, was already overexploited by shrimp trawlers and the longline fleet, and recent observations suggest further deteriorations in this system. To evaluate the ecosystem and socioeconomic changes in the Gulf of Nicoya over the last 20 years, the 1993 model was reconstructed with data from 2013 to compare both system states. Although the summary statistics of both states (i.e., 1993 and 2013) suggested that the system maintained its general functionality and even enabled the total harvest to increase by approximately 20%, a more detailed analysis of the levels of the functional groups suggested that the system was further degraded as follows: (1) most shrimp, eel, and catfish species decreased their share in the catches, with severe economic losses for the fishery; (2) of the species that substantially increased their share in the catches, most were short‐lived, low‐value species, such as small pelagic and small demersal fishes; and (3) catches of long‐lived, high‐trophic‐level fish, such as rays, sharks, mackerels, and barracudas, decreased. A picture emerged in which the advancing fishery of low‐trophic‐level species with low economic value enabled the total harvest to increase, while valuable shrimp resources and higher‐trophic‐level species were depleted. These developments caused a tremendous economic loss of approximately 50%.
