Sri Lanka: Action stations
No full textSri Lanka’s National Fisheries Policy needs to be remodelled to incorporate the SSF Guidelines in order to attain the goal of securing sustainable small-scale fisheries. The Ministry of Fisheries and Aquatic Resources Development (MFARD) of Sri Lanka recently prepared a White Paper on National Fisheries Policy in 2018, which was approved by the Cabinet and is expected to be presented to the parliament. It fails to address a number of compelling needs of the small-scale fisheries sector. The Sri Lanka Forum for Small-Scale Fisheries (SLFSSF) responded to this need; it embarked on a process to implement the Voluntary Guidelines for Securing Sustainable Small-Scale Fisheries in the Context of Food Security and Poverty Eradication (the SSF Guidelines) between July 2018 and May 2019, with assistance from the International Collective in Support of Fishworkers (ICSF), as part of efforts of the Food and Agriculture Organization of the United Nations (FAO) towards global implementation of the SSF Guidelines. Following the FAO Project Results Matrix, the SLFSSF took up a number of activities
Gender: A platform for women
No full textWomen in fisheries can utilize the SSF Guidelines to advance their interests, even as they relate to one another and build up solidarity and a common vision. In India, in 2016, the International Collective in Support of Fishworkers (ICSF) had organized a large national workshop to discuss the provisions of the SSF Guidelines with women in fisheries from various states (provinces). A follow-up workshop was organized in August 2019, this time focusing on states where women are better organized, in order to help them take the discussion towards concrete action. This was also in the backdrop of the National Policy on Marine Fisheries (NPMF), which was notified in late 2017 by the Government of India. It was deemed necessary to understand whether or not there was convergence of this national policy with the provisions of the SSF Guidelines
From the editor, Yemaya, no.60, April 2020
Full text linkThe 60th issue of Yemaya, being brought out after a gap of a year, coincides with a time of global crisis, when nations and communities across the world are battling the effects of the COVID 19 pandemic. It is a time for sombre thought and reflection. This pandemic has also locked down coastal fishing communities and seriously impacted livelihoods. The case study from Maharashtra, India, in this issue of Yemaya, details the impact on women fishers. Earnings have dropped because of lack of fish, market access, traditional credit sources and clear government policy enabling relief. In India, the government’s move to keep the fishing sector open during lockdown helped to vindicate the importance of the sector but the curfew-like conditions of the prevailing lockdown prevented women fishers from availing the benefits of the move. Clearly, the challenges before women fishers and fishworkers have multiplied
Africa: women marching on! Milestones in CAOPA’s march for the rights of women in African artisanal fisheries
Full text linkOn 19 March 2010, in Banjul, The Gambia, men and women professionals from the artisanal fishing sector from nine West African countries presided over the formation and launch of the African Confederation of Artisanal Fishing Organisations: CAOPA. Ten years later, CAOPA has become an advocacy platform for African artisanal fishing community rights, entering into dialogue with African decision makers, as well as with international partners, like the EU and the FAO. CAOPA is now also stronger: it has member organisations in 24 countries from West, East, and North Africa and from the Indian Ocean. Every 21st November, CAOPA uses the occasion of the World Fisheries Day to establish its advocacy agenda for the year to come
Stock Assessment of Arius maculatus (Thurnberg, 1792) (Ariidae, Siluriformes) in Panguil Bay, Northwestern Mindanao
Full text linkArius maculatus, commonly known as spotted catfish and locally known as Tambangongo, has a great potential as an aquaculture species, but there is very limited information known for the stocks in Panguil Bay. This study aimed to assess the wild stocks of A. maculatus, and make an inventory of the fishing boat and gears in two stations in Panguil Bay, namely: Tangub, Misamis Occidental and Baroy, Lanao del Norte. Length frequencies were analyzed to provide estimates of growth, mortality, exploitation ratio, and recruitment pulse of A. maculatus in the bay. A total of 589 boats (324 motorized boats and 265 non-motorized boats) were recorded from the sites. There were 473 units of 15 types of fishing gear used in the sites and 6 types of these were only used in catching A. maculatus. A total of 3,259 specimens were collected for 12 months from the sites. The aquatic habitat of A. maculatus from the two sites was characterized by a pH range of 7.9-8.1, temperature of 28.5-29.1°C, salinity of 13.31-15.9 ppt, dissolved oxygen levels of 4.0-5.41 ppm, and total suspended solid values of 0.1-0.6 g/L. Reproductive biology analysis indicates that eggs start to mature from October to December, then spawning starts from January to March, and the fish fry recruitment starts in April and May. A. maculatus can grow up to 98.95 cm with an asymptotic length of 98.86 cm (K value = 0.35) equivalent to asymptotic weigth of 8,750 g. Mortality Z = 0.99, with natural mortality M = 0.67 and fishing mortality F = 0.33. This study revealed that A. maculatus in Panguil Bay is not over-exploited since the exploitation rate (E = 0.33) is minimal and large individuals can still be collected from the field
Pesca recreativa competitiva desde la costa en el sur de Bahía, Brasil: un estudio de referencia
Full text linkEste estudio describe eventos competitivos de pesca desde la costa en Ilhéus, sur de Bahía (Brasil), incluida la composición de la captura, y proporciona información sobre el perfil de los pescadores recreativos que participan en estos eventos. La información se recopiló en todos los eventos promovidos por el Clube de Pesca de Ilhéus (CLUPESIL) en 2007-2008. Se organizaron un total de 26 eventos de pesca competitiva durante este período con 47 especies capturadas. Las principales especies fueron: Cathorops spixii, Menticirrhus littoralis, Trachinotus goodei, Eucinostomus melanopterus, Polydactylus virginicus, Atherinella brasiliensis y Eucinostomus argenteus. Estas siete especies representaron el 87% de la captura total en número y el 78% en peso. Menticirrhus littoralis y Polydactylus virginicus son especies de interés comercial y su captura estuvo dominada por juveniles. Los pescadores recreativos locales eran predominantemente hombres de mediana edad, que solían usar anzuelos pequeños y principalmente camarones como carnada. Estaban orientados al consumo, pero también liberaron peces pequeños. Durante las competiciones, los pescadores usaron anzuelos incluso más pequeños. La mayoría de ellos percibió a el arrastre de camarones como el principal factor que afecta la pesca recreativa. Se sugiere el uso de anzuelos más grandes y un tamaño mínimo de 20 cm para disminuir la captura de juveniles, principalmente los de especies de importancia comercial. Este estudio establece una línea de base a partir de la cual se pueden proponer nuevos estudios para acceder al estado actual de la pesca recreativa local
Nutrition: fish as food
Full text linkThe international democratic process has come a long way in realizing the role of fish in the right to food and nutrition–and yet, a map of the road ahead needs to be laid out. Even though the last century has seen great socioeconomic advances and improvement in human well-being worldwide, much work remains to be done to realize the ultimate goal of the Food and Agriculture Organization of the United Nations (FAO) to contribute to a “world free from hunger and malnutrition, where food and agriculture contribute to improving the living standards of all, especially the poorest and marginalized in an economically, socially and environmentally sustainable manner”

Groundwater relationships to pumping, precipitation and geology in high-elevation basin, Sierra Valley, CA
Full text linkSierra Valley, located in the northern Sierra Nevada, California, serves as the Middle Fork Feather River headwaters and provides surface water to Oroville Dam of the California State Water Project (SWP). Under California’s Sustainable Groundwater Management Act (SGMA), the Sierra Valley sub-basin has been designated a medium-priority basin, due to chronic groundwater declines and the valley’s high ecological value as the largest freshwater marsh and meadow system in the Sierra Nevada. The Sierra Valley Groundwater Management District (SVGMD) serves as the Groundwater Sustainability Agency (GSA) for the Sierra Valley sub-basin. As such, SVGMD is tasked through SMGA with achieving sustainable groundwater management over an approximate 20-y timeframe. The first step is the development of a Groundwater Sustainability Plan (GSP) (to be completed by January 2022) that 1) hydrologically assesses the basin, 2) identifies methods and protocols to track groundwater trends, and 3) develops an initial suite of actions to move the basin towards groundwater sustainability. ...
Our investigation builds on previous watershed studies and further establishes the Sierra Valley watershed as a highly complex hydrologic system. These complexities include: large variation in precipitation phase and quantity throughout the watershed; geologic features that restrict both vertical and lateral groundwater flow; many water inflow pathways, both surface and sub-surface, that are logistically impossible to quantify by conventional monitoring means. Prior attempts at developing accurate water budgets and numerical models of the watershed have been hindered by the uncertainty these factors present. Thus, though a hydrologic budget is required by SGMA for the development of the GSP, numerical models will be of limited utility as either tools to derive hydrologic budgets or to help determine the efficacy management actions to achieve sustainable groundwater conditions.
In developing strategies to address undesirable groundwater conditions, we recommend an adaptive management approach paired with targeted and defensible data collection with standardized data collection, management and quality control procedures
Comportamiento reproductivo del pulpito patagónico (Octopus tehuelchus) en condiciones de laboratorio
Full text linkEl pulpito patagónico (Octopus tehuelchus) es una especie que mantiene una pesquería artesanal en la zona norte de la costa patagónica argentina y que presenta potencial para la acuicultura. Este trabajo tuvo el objetivo de caracterizar el comportamiento de apareamiento de cuatro parejas de pulpitos patagónicos en condiciones de laboratorio. Los resultados muestran que esta especie presenta un complejo comportamiento reproductivo. La hembra se mantuvo en su refugio durante los eventos de pre-cópula y copula. El macho y la hembra permanecieron enfrentados por la cara oral durante la cópula la cual duró de 3 a 5 minutos. Las observaciones realizadas contribuirán a un mejor manejo de los ejemplares reproductores de la especie en cautiverio
