Ross Sea marine reserve proposal The remote Ross Sea supports a biologically diverse ecosystem that has thrived essentially unchanged for millennia. In fact, a 2011 study published in the journal Biological Conservation called the Ross Sea “the least altered marine ecosystem on Earth.” This area of the Southern Ocean provides habitat for Antarctic toothfish, a top predator in the region’s food web. These fish, also known as Chilean sea bass, are highly prized by the commercial fishing industry, but the threat of overfishing could disrupt the ecological balance of the Ross Sea and beyond. The United States and New Zealand have co-sponsored a proposal at the Commission for the Conservation of Antarctic Marine Living Resources to create a marine protected area of 1.25 million square kilometers (about 482,000 square miles) in the Ross Sea. Of that, 1.14 million square kilometers (about 440,156 square miles) would be off-limits to fishing. Though the proposal would allow limited commercial catch of Antarctic toothfish, as well as some fishing in a “special research zone” along the continental shelf and slope, it would protect huge swaths of ocean from overfishing and ensure that much of this near-pristine ocean ecosystem remains untarnished for the future.

Harmful Environmental Exposures and Vulnerable Populations Environmental Health in Nursing
Unit II: Harmful Environmental Exposures and Vulnerable Populations Environmental Health in Nursing Unit 1I: Harmful Environmental Exposures and Vulnerable Populations INTRODUCTION Unit 1 highlighted various roles of the nursing profession where knowledge of environmental exposures is central to practice. In Unit 2, the focus is upon population groups who are most vulnerable to harmful environmental exposures. While risks to adverse health outcomes can vary according to geography, housing and location of environmental exposures, some humans are at greater risk due to their biophysical and sociopolitical vulnerability. Unit 2 explains risk and vulnerability across the lifespan with a focus upon speciﬁc vulnerabilities and harmful effects at various developmental stages. A second chapter highlights anticipatory guidance for parents and caregivers to reduce environmental exposures for children from infancy to adolescence. Third, Unit 2 considers the impact of social determinants of health, which are commonly referred to as factors where people live, learn, work, play and pray. Social determinants at neighborhood and community levels impact individual level exposures. Finally, Unit 2 includes a chapter about the effects of social determinants on the vulnerability of immigrants and refugees. See Unit 5: Sustainable Communities, for the chapter about Environmental Justice, which addresses the adverse outcomes for those who live in more environmentally hazardous areas.

Almost all crime at sea takes place beyond the horizon line, hidden from view. This vast wilderness is exploited not only for fish, but as a hiding place for criminal activities. Stolen fish are caught illegally, evading a wide range of safeguards to undercut the costs of doing business. Blatant violation of catch limits, gear restrictions and safety precautions are frequently carried out by a small fraction of fishermen, undermining the efforts of responsible “Illegal, unregulated and unreported fishing is a fishing companies.

Best Fish for Your Health and the Sea's
Nova In Vitro Fertilization Best Fish for Your Health and the Sea's By The Green Guide Editors (National Geographic) Fish provide essential nutrients and fatty acids—especially for developing bodies and brains and make a perfect protein-filled, lean meal whether grilled, baked, poached or served as sushi. Yet overfishing, habitat loss and declining water quality have wreaked havoc on many fish populations. Furthermore, many are contaminated with brain-damaging mercury and other toxic chemicals. If the pickings appear slim, check out our "Yes" fish where you'll find many options available. As for our "Sometimes" fish, these may be eaten occasionally, while "No" fish should be avoided entirely. Photograph Courtesy Shutterstock Images Warnings are based on populations of highest concern (children and women who are pregnant, nursing or of childbearing age). To learn which fish from local water bodies are safe to eat, call your state department of health, or see www.epa.gov/waterscience/fish. Besides mercury, toxins can include PCBs, dioxins and pesticides. In compiling this list, the Green Guide referred to resources at the web sites of the Food and Drug Administration, Monterey Bay Aquarium, Environmental Working Group, Environmental Defense Foundation and Oceana among others.

This constitutes one of the longest biological time series in the Southern 18 Ocean, and certainly the longest for any fish. Fish total length, condition and catch per unit 19 effort (CPUE) were derived from the >5500 fish caught. Contrary to expectation, length- 20 frequency was dominated by fish in the upper half of the industrial catch. The discrepancy may 21 be due to biases in the sampling capabilities of vertical (this study) versus benthic (horizontal) 2 22 fishing gear (industry long lines), related to the fact that only large Antarctic toothfish (>100 cm 23 TL) are neutrally buoyant and occur in the water column. Fish length and condition increased 24 from the early 1970’s to the early 1990s and then decreased, related to sea ice cover, with lags 25 of 8 months to 5 years, and may ultimately be related to the fishery (which targets large fish) 26 and changes in the Southern Annular Mode through effects on toothfish’ main prey, Antarctic 27 silverfish Pleuragramma antarcticum.

Biodiversity of Chilean Sea Anemones (Cnidaria: Anthozoa): Distribution Patterns and Zoogeographic Implications, Including New Records for the Fjord Region*
Invest. Mar., Valparaíso, 34(2): 23-35, 2006 Biogeography of Chilean sea anemones 23 Biodiversity of Chilean sea anemones (Cnidaria: Anthozoa): distribution patterns and zoogeographic implications, including new records for the fjord region* Verena Häussermann Fundación Huinay, Departamento de Biología Marina, Universidad Austral de Chile Casilla 567, Valdivia, Chile ABSTRACT. The present paper provides a complete zoogeographical analysis of the sea anemones (Actiniaria and Corallimorpharia) of continental Chile. The species described in the primary literature are listed, including depth and distribution records. Records and the taxonomic status of many eastern South Paciﬁc species are doubtful and need revision and conﬁrmation. Since 1994, we have collected more than 1200 specimens belonging to at least 41 species of Actiniaria and Corallimorpharia. We sampled more than 170 sites along the Chilean coast between Arica (18°30’S, 70°19’W) and the Straits of Magellan (53°36’S, 70°56’W) from the intertidal to 40 m depth. The results of three recent expeditions to the Guaitecas Islands (44°S) and the Central Patagonian Zone (48°-52°S) are included in this study. In the fjord Comau, an ROV was used to detect the bathymetrical distribution of sea anemones down to 255 m. A distribution map of the studied shallow water sea anemones is given. The northern part of the fjord region is inhabited by the most species (27). The results show the continuation of species characteristic for the exposed coast south of 42°S and the joining of typical fjord species at this latitude. This differs from the classical concept of an abrupt change in the faunal composition south of 42°S.

The discrepancy between the reconstructed total catch and the reported landings was fairly steady for the whole time period, with the reconstructed catch being 16% higher than SERNAPESCA reported landings and 24% more than data reported by FAO on behalf of Chile. Reconstructed total landings in Chile show that the main pelagic species (Trachurus murphy, Engraulis ringens, Sardinops sagax and Clupea bentincki), which are mostly used for fishmeal production, account for 82% of total landings.
