“…sole in the Adriatic Sea; STECF 2013), although management of this stock does not take the assessment results into consideration but is based solely on technical measures. In Vietnam, a TAC (Total Allowable Catches) management system is in place, although the TAC setting is not based on quantitative stock assessment and the real impact of the fleet on the stock is unkown (Pomeroy et al 2009). …”

Summary:Artisanal fisheries are often overlooked by fisheries management agencies despite their great importance for food security and livelihoods. The assessment and management of those fisheries is often rare, especially in developing countries. In Mozambique, a probability-based survey for the monitoring of the small-scale fisheries has been conducted in several coastal provinces since the late 1990's. Here we used the Mozambican on-shore data collection programme to illustrate both the difficulties and possibilities of estimating trends in catch per unit of effort (CPUE in kg day -1 ) for stocks when data is limited in both quantity and quality, as is often the case for artisanal fisheries. Data on catch and effort collected between 1998 and 2009 from four regions along the Mozambican coast and two different gears were used to assess the status of two species (Hilsa kelee and Thryssa vitrirostris) exploited by the artisanal fisheries. The results showed that standardized CPUE have declined for some of the regions and gears analysed, whereas for others the trend has been stable or has even increased during the last 12 years. However, when CPUE is scaled for the increase in net length, most of the times series show a declining trend.Keywords: artisanal fisheries; Mozambique; CPUE.Tendencias de la CPUE de Hilsa kelee y Thryssa vitrirostris explotadas por la pesquería artesanal en Mozambique a partir del muestreo de las capturas en puerto Resumen: La pesca artesanal casi nunca se tiene en cuenta por las agencias de gestión de la pesca a pesar de su gran importancia para la seguridad alimentaria y medios de vida. La evaluación y la gestión de estas pesquerías no es muy frecuente, especialmente en los países en desarrollo. Desde finales de 1990 en varias provincias de la costa de Mozambique se llevó a cabo un seguimiento de las pesquerías artesanales basado en un muestreo probabilístico. Aquí hemos utilizado el programa de obtención de datos en el puerto de Mozambique para ilustrar las dificultades y posibilidades de la estimación de las tendencias de la captura por unidad de esfuerzo (CPUE en kg día -1 ) para los stocks cuando los datos son limitados en cantidad y en calidad, como sucede a menudo en el caso de la pesca artesanal. Se utilizaron datos de captura y esfuerzo recogidos entre 1998 y 2009, en cuatro regiones a lo largo de la costa de Mozambique y con dos artes de pesca distintos, para evaluar el estado de las dos especies (Hilsa kelee y Thryssa vitrirostris) explotadas por las pesquerías artesanales. Los resultados mostraron que la CPUE estandarizada se ha reducido para algunas de las regiones y artes analizados, mientras que para otros la tendencia se ha mantenido estable o incluso ha aumentado durante los últimos 12 años. Sin embargo, cuando se escala la CPUE para el aumento de la longitud de la red, la mayor parte de la serie de tiempos muestra una tendencia a la baja.

“…At the regional level, addressing the ongoing SCS territorial dispute, which impedes regional cooperation, is a major challenge that requires the involvement of intra-governmental and international bodies. Nationally, recommendations for reducing the chronic overcapacity in SCS fisheries span a range of input, spatial, and temporal restrictions, as well as the integration of broader, inter-sectoral environmental planning in conjunction with fisheries management (Pomeroy et al 2009;Huang and Chuang 2010;Perez et al 2012;Pomeroy 2012;Wu 2014). The huge dependence on smallscale coastal fisheries in the SCS also makes the integration of socio-economic policy within fisheries management imperative.…”

“…Inshore waters are subject to intense fishing pressure from heavily populated coastal areas (Cheung and Sadovy 2004;Pomeroy et al 2009;Huang and Chuang 2010;Hughes et al 2013;Muallil et al 2014). For instance, a density of 16 fishers km -2 was recorded in the Lingayen Gulf of the Philippines, which was four times higher than the threshold level of 4 fishers km -2 required for sustaining catch levels that can meet poverty needs (Cruz-Trinidad et al 2009).…”

“…However, this assessment may have contained high uncertainty because it was based on existing reports, publications, and expert judgement (FAO 2010), and appears inconsistent with prior stock status assessments which indicated that marine fisheries throughout the Philippines were growth overfished from the 1980s onwards (Palomares and Pauly 2014). Inshore fisheries in Vietnam were also considered to be severely overexploited (Pomeroy et al 2009). Offshore fisheries showed a general decline nationwide, although deep water demersal and meso-pelagic resources in central and southern offshore waters were not considered to be overexploited (Anonymous 2005).…”

“…Qualitative accounts of temporal declines in catch rates are common in SCS small-scale fisheries (Teh et al 2008;Pomeroy et al 2009;Muallil et al 2014). Similarly, the majority of assessed SCS fisheries showed a temporal decline in catch rates (Funge-Smith et al 2012).…”

Governance of South China Sea (SCS) fisheries remains weak despite acknowledgement of their widespread overexploitation for the past few decades. This review incorporates unreported fish catches to provide an improved baseline of the current status and societal contribution of SCS marine fisheries, so that the socio-economic and ecological consequences of continued fisheries unsustainability may be understood. Potential fisheries contribution to food and livelihoods include 11-17 million t in fisheries catch and USD 12-22 9 10 9 in fisheries landed value annually in the 2000s, and close to 3 million jobs. However, overfishing has resulted in biodiversity and habitat loss, and altered ecosystem trophic structures to a 'fished down' state. The present situation reiterates the urgency for fisheries policies that simultaneously address multiple political, social, economic, and biological dimensions at regional, national, and local scales. Importantly, improved cooperation between SCS nations, particularly in overcoming territorial disputes, is essential for effective regional fisheries governance.
