    • Ocean Literacy for All: a toolkit.

      Santoro, Francesca; Santin, Selvaggia; Scowcroft, Gail; Fauville, Géraldine; Tuddenham, Peter; International Oceanographic Commission (IOC/UNESCO & UNESCO Venice OfficeParis, France, 2018)
      Recognizing the lack of ocean-related subjects in formal education, a group of ocean scientists and education professionals in the US in 2002 initiated a collaborative and bottom-up process to develop a comprehensive framework to encourage the inclusion of ocean sciences into national and state standards, and for more teaching about the ocean in K-12 classrooms. This was the start of the ocean literacy movement that since then it has spread around the world through the development of marine science educators associations in Canada, Australia, Europe and Asia. Ocean literacy programs and projects, until now, have been mainly focusing on developing resources, lesson plans and activities targeting Science, Technology, Engineering and Mathematics (STEM) education. Currently, and in particular after the adoption of the Sustainable Development Goal (SDG) 14, we have assisted to a shift in the focus towards the inclusion of approaches closer to those developed under the UNESCO framework of Education for Sustainable Development (ESD). ESD aims to improve access to quality education on sustainable development at all levels and in all social contexts, to transform society by reorienting education and help people develop knowledge, skills, values and behaviors needed for sustainable development. Individuals are encouraged to be responsible actors who resolve challenges, respect cultural diversity and contribute to creating a more sustainable world. This publication is made of two parts. The first part presents the history of ocean literacy, and describes its framework made of 7 essential principles, and connects them to international ocean science programs that contributes to enhancing ocean knowledge and observations. Moreover, marine scientists and educators were interviewed to share their professional experiences on ocean literacy as well as their views on its future. The last chapter of part 1 describes the existing challenges to marine education, as well as the path for the development of successful ocean literacy activities in the context of the 2030 Agenda. One of the most important factors identified is related to the creation of multi-sector partnerships among the education, government, and private sector that have jointly built ocean literacy programs for all formal educational levels from the primary school to the university level as well as for non-formal learners. Worldwide examples of such programs are presented. The second part, after introducing the methodological approach based on the multi-perspective framework for ESD developed by UNESCO, presents 14 activities that could provide tested examples and support for the implementation of marine education initiatives. The aim is not to provide a one size-fits-all ready to use collection, but rather to offer support and examples of what could be then adapted for different geographical and cultural contexts. The resources are designed to be relevant for all learners of all ages worldwide and to find their application in many learning settings, while in their concrete implementation they will, naturally, have to be adapted to the national or local context.

      Ali, Qadeer Mohammad; Ghory‎, Farhana S.; Ahmed, Quratulan; Siddique, Saima; Mubarak, Shumaila; Memon, Sehrish (2019-12-31)
      Rocky shores are considered heterogeneous environments due to their composition and ‎structure. Therefore, they support numerous habitats for flora and fauna. Organisms ‎found on rocky shores are facing intense physicochemical conditions during tidal ‎changes from upper to lower intertidal zones. Total (N=1888) specimens were collected ‎on seasonal basis from intertidal zone during low tide from two rocky sites of Karachi ‎coast, Buleji and Sunehri during January 2017 to December 2017. The highest number ‎of individuals (N=1041), were recorded from Buleji than Sunehri (N= 847). The seasonal ‎abundance in Mollusca were measured as (36.84%), (63.67%), (25.08) and (40.38%) ‎from Buleji while from Sunehri (45.16 %), (46.01%), (48.65) and (42.79 %) during pre-‎monsoon, south-west monsoon, post monsoon and north-east monsoon season ‎respectively. Group Arthropoda, Mollusca and Echinodermata were shows the highest ‎abundance of the species at both sites as compare to other groups. The highest diversity ‎index from Sunehri (H'=0.64) was measured in north-east monsoon season meanwhile, ‎‎(H'=0.61) was measured in post monsoon season from Buleji coast. Evenness index ‎‎(J'=0.25) in pre-monsoon season from Buleji and (J'=0.28) in south-west monsoon season ‎from Sunehri coast . Season shows the great abundance of species as compare to other ‎seasons. No significant correlation was observed in between seasons, water temperature ‎and salinity with macrofauna groups at both sites. ‎
    • Empirical use of growth, mortality and temperature data for anchovy.

      Bilgin, Sabri (2019-12-31)
      To estimate the empirical relationships in anchovy, the instantaneous natural mortality ‎rate (M) calculated from von Bertalanffy Growth Function (VBGF) parameters, ‎maximum total length (Lmax) and sea surface temperature (T,°C) were reviewed in the ‎Black Sea. Empirical equations were presented for evaluation of M data in their ‎relationships to VBGF parameters, T and Lmax. Based on biological consideration and ‎regressional definition, it was recommended to use following formulas for estimating of ‎natural mortality rate of small pelagic fish such as anchovy. M = 0.3237 + 1.3174*(K) - ‎‎0.0036*(L∞) - 0.0117*(T); M = 0.2639 + 1.3676*(K) - 0.0003*(Lmax) - 0.0124*(T).‎

    • Variación espacio-temporal en la salud de los corales hermatípicos en un arrecife en la región noroccidental de Cuba

      Aguilera Pérez, Gabriela C. (Universidad de La Habana, 2020)
      Los arrecifes de coral se encuentran dentro de los ecosistemas marinos más impactados por el cambio climático y por impactos de origen antrópico. En consecuencia, el objetivo de la tesis fue evaluar el estado de salud de las comunidades de corales del arrecife costero de calle 16, Playa, La Habana. Se realizó un análisis espacial entre los biotopos de Veril superior, Veril caída y Camellones; y un análisis temporal durante el verano (agosto) y después del verano (octubre) de 2019. La unidad de muestreo fue el transecto de banda (10m de largo por 1m de ancho), ubicándose 10 réplicas en cada biotopo. Como indicadores ecológicos se utilizaron: la salud de los corales, la riqueza de especies, la diversidad de Shannon, la equitatividad de Pielou, la composición por especies, la densidad de corales y la densidad por especies. Para evaluar la salud se establecieron las categorías: blanqueamiento, mortalidad antigua, mortalidad reciente, organismos bioerosionadores y enfermedades activas. Para el análisis espacial y temporal a nivel de población se seleccionaron las especies: Siderastrea siderea (Ellis y Solander, 1786), Porites astreoides (Lamarck, 1816), Montastraea cavernosa (Linnaeus, 1767) y Agaricia agaricites (Linnaeus, 1758). Se realizó un análisis temporal de la temperatura en el arrecife, a partir de datos registrados por sensores de temperatura ubicados en los tres biotopos. La diversidad de Shannon y la equitatividad de Pielou fueron superiores en Camellones (H’= 2,32 y J’= 0,76). En el Veril superior se encontró la mayor densidad de corales (14,7 ± 0,97 colonias/m2). Siderastrea siderea constituyó la especie dominante para todo el arrecife. El biotopo con mayor incidencia de afectaciones fue el de Camellones (66% de las colonias afectadas). Las afectaciones más importantes que se encontraron en el arrecife fueron el blanqueamiento (15-55%) y la mortalidad antigua (5-15%). El porcentaje de colonias blanqueadas y de superficie blanqueada aumentó significativamente después del verano (15-60% antes del verano y 40-60% después del verano). El análisis de la temperatura media mensual mostró que el valor máximo se alcanzó en el mes de septiembre (31,3oC) en los Camellones. Las especies con mayor porcentaje de blanqueamiento fueron S. siderea y A. agaricites. La mortalidad antigua afectó, fundamentalmente, a la especie M. cavernosa. La abundancia de las especies ingenieras (M. cavernosa, O. annularis y O. faveolata; con excepción de S. siderea) ha disminuido, mientras que las de las especies oportunistas y fenotípicamente plásticas, como P. astreoides, ha aumentado. La baja incidencia de enfermedades y de mortalidad reciente (ambas por debajo del 1%) se podría considerar como un buen indicador del estado de la comunidad coralina de este arrecife en comparación con el resto del Caribe y otros sitios de Cuba. El análisis integral de los indicadores ecológicos analizados, mostró deterioro en la condición del arrecife de calle 16. Ello sugiere reevaluar la utilización del arrecife como sitio de referencia en el diseño de investigaciones futuras en el contexto de La Habana.

    • Milestones: pulled backward

      Lakshmi, Ahana (2020)
      The impact of the COVID-19 pandemic on SDG 5. The Sustainable Development Goals (SDGs) were adopted by all United Nations Member States in 2015 as a universal call to action to end poverty, protect the planet and ensure that all people enjoy peace and prosperity by 2030. How has progress towards this end been affected by the COVID-19 pandemic? A new report, the Sustainable Development Goals Report 2020, released in July by the United Nations Development Programme (UNDP) presents an overview of progress towards the SDGs before the pandemic started, but it also looks at some of the devastating initial impacts of COVID-19 on specific goals and targets. We focus here on SDG 5: Gender equality and empower all women and girls.
    • What’s new, webby?: covering COVID-19

      Roshan, Manas (2020)
      Since its outbreak in Wuhan, China, in December 2019, COVID-19 has spread to 202 countries and territories, leading to 14,508,892 confirmed cases and 606,206 deaths as on 20 July, 2020. ICSF SAMUDRA and DC daily news alerts have tracked the impacts of the COVID-19 outbreak on fisheries value chains since the early stages of the pandemic. Launched in May, ICSF’s new website ( has drawn on these news alerts and information from ICSF’s networks of members and partners to map the effects of lockdown restrictions, closure of markets and restaurants, and changes in demand and supply of fish and fish products around the world.
    • Brazil: fishing for crustaceans

      Ferreira, Beatriz Mesquita Pedrosa (2020)
      This photo-essay depicts the practice of aratu fishing carried out by women in the mangroves of northeastern Brazil. Aratu (Goniopsis cruentata) are small, reddish crustaceans that live on the branches of mangroves. They are processed and sold, the sweetness of the meat making them a prized delicacy. Aratu fishing is carried out mostly by women, for whom it is a source of income, allowing them to get by without formal employment, and offering a certain freedom in their lives. Unlike the crab, the aratu is a fast breeder but both types of crustaceans have their own pros and cons. “If aratu bred like crab, there wouldn’t be much to pick since there are a lot of people fishing. We’re lucky that it reproduces fast. Crab is less labour intensive and fetches more money. Aratu has to be picked before it is sold; crab doesn’t need any such processing”
    • Mexico: pandemic outcomes

      López-Ercilla, Inés; Torre, Jorge; Solano, Neyra; Fernández, Francisco (2020)
      Women in the small scale fishing sector in Mexico are key drivers ensuring food security and community wellbeing during the COVID-19 pandemic. The impacts of the COVID-19 pandemic have surpassed all imaginable scenarios. The global crisis moves fast and changes quickly, hence forcing people to adapt and navigate through uncertainty as never before. Every generation faces impacts that shake their minds and force them to leave their comfort zone. This is an impact for a lifetime, for current and new generations. Other shocks have posed risks to fisheries before; some of them being global (climate change), regional (overfishing) or even local (illegal fishing, poverty, poor fishing management tools, lack of enforcement), to name only a few. However, the impact of the current pandemic greatly eclipses these in terms of scale and outcome.
    • Brazil: reaching out, holding hands

      França, Lorena; Silva, Luclécia Cristina Morais da; Ferreira, Beatriz Mesquita Pedrosa (2020)
      The President of the Association of Indigenous Communities of the Middle Negro River (ACIMRN), Sandra Gomes, speaks about the challenges indigenous communities face due to the COVID-19 pandemic. The Negro River in the Amazon region is the largest black water river in the world. Its basin area of approximately 750,000 sq. km accounts for seven percent of the total area of the Amazon basin, and its length from pre-Andean Colombia to its mouth, is approximately 1,700 km, making it the Amazon’s largest tributary.
