“…Artisanal fisheries that target stocks within the coastal ecosystems have been largely ignored by fisheries management agencies, despite their great importance for food security and livelihoods (Vincent et al 2007). It has been shown that local artisanal fisheries with a relatively low level of effort and technological development can significantly impact the coastal environment and the coral reef ecosystem, and therefore the monitoring of their impact is important (Hardt 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.

“…Current understanding of seahorse fisheries comes primarily from haphazard sampling during the first and second surveys, supplemented by a few sets of landing data and catch records (Meeuwig et al , 2006 for by‐catch in trawls; Vincent et al , 2007 for target catch). The Queensland east coast otter‐trawl fishery may maintain the only mandated tracking of syngnathid landings, requiring records of all by‐catch of syngnathids because they are species of conservation interest in Queensland (Dodt, 2005).…”

“…They live in corals, seagrasses, macroalgae, mangroves, estuaries, lagoons and open bottom habitats and can be important predators on bottom‐dwelling organisms (Tipton & Bell, 1988; Bologna, 2007). Subsistence fishers in some nations make a substantial portion of their annual income catching seahorses (Pajaro et al , 1998; Vincent et al , 2007) for use in ornamental display, curios and traditional medicine (Vincent, 1996; Parry‐Jones & Vincent, 1998; May & Tomoda, 2002; Alves & Rosa, 2006; Qian et al , 2008; Vincent et al , 2011). They are often featured in art and stories and are attractive enough to draw considerable public support for their conservation and for the larger marine environment (Scales, 2009).…”

This article analyses the pressures on seahorses and explores conservation responses. It focuses on seahorses (Hippocampus spp.) but also considers pipefishes and seadragons, especially where they can fill gaps in seahorse knowledge. The charisma of many syngnathids can make them good flagship species for threats and solutions in marine conservation. The article combines a synthesis of published literature with new data on the trade in seahorses for traditional medicine, aquarium display and curiosities. Most traded seahorses come from trawl by-catch, although seahorses are also targeted. The total extraction is large, tens of millions of animals annually, and unsustainable. A first review of the effect of habitat change on syngnathids raises many questions, while suggesting that some species may cope better than others. The combination of pressures means that many species of syngnathid are now included in the IUCN Red List of Threatened Species or national equivalents. In addition, seahorse exports from 175 countries are limited to sustainable levels under the Convention on International Trade in Endangered Species (CITES) of Wild Fauna and Flora. Possible conservation measures include marine protected areas, fisheries management, select aquaculture ventures, trade regulation, improved governance (particularly) and consumer engagement.

“…Other countries such as Mexico, India, and Vietnam exported only dried seahorses. Furthermore, Sri Lanka traded only live seahorses (Vincent et al 2007(Vincent et al , 2011. Mexico, South Africa, France, Portugal, Slovenia, Malaysia, and India have presently included seahorses in the list of protected species (Lourie et al 2004).…”
