Diver observations of community structure on a subarctic marine artificial reef in Whittier, Alaska

Creator:: Levy, Charlotte
Abstract:: Increased coastal development poses a potential threat to nearshore habitats in Alaska, and artificial reefs (AR) are an increasingly popular tool for mitigating habitat loss. Although well studied in tropical and temperate locations, less is known about AR efficacy in high latitude locations. Since ARs are heavily influenced by ecological...

Modification of furfural and hydroxymethylfurfural by manganese(III)

Creator:: Morse, Lettie
Abstract:: Biomass pretreatment-derived degradation compounds, such as furfural and 5-hydroxymethyl-furfural (HMF),inhibit the growth of fermentation microorganisms that utilize biomass to produce biofuels and chemicals. Here we report that manganese(III) can degrade furfural and HMF, making them less toxic to microorganisms. Treatment with manganese(III) reduced furfural and HMF concentrations in a dose-dependent...

Impacts of the 2008-2009 US West Coast Salmon Ocean Fishery Closure on Salmon Troll Vessels

Creator:: Richerson, Kate and Holland, Dan
Abstract:: As anthropogenic changes interact with natural climate cycles, the variability of marine ecosystems is likely to increase. This variability influences the behaviour of fishers, which can affect the profitability and sustainability of stocks and may have wider economic and ecological effects. We use data from the US West Coast salmon...

The Value of Eco-Labels through Revealed Consumer Preferences for Seafood in San Diego County

Creator:: Poindexter, Oriana
Abstract:: Seafood markets are the inflection point in the fish-to-food transformation, and act as windows into revealed consumer preferences for seafood selection. These preferences have far-reaching implications for fisheries management, food security, and marine conservation. This study reveals consumer preferences for seafood in San Diego County by quantifying the relationship between...

A Double Hurdle Application of Fishermen’s Catch Sales Through Fish Mothers in Ghana

Creator:: Quagrainie, Kwamena and Chu, Jingjie
Abstract:: A significant proportion of catch by artisanal fishers in Ghana is sold through wealthy middle-women, known as “fish mothers,” who often pre-finance fishing trips. This study examined the determinants of catch sales through fish mothers. Data used came from artisanal fishermen at major coastal fishing communities in Ghana. The effects...

Catch Quotas for the Pacific Hake Fishery in the Gulf of California

Creator:: Ramirez-Rodriguez, Mauricio
Abstract:: Fishing for Pacific Hake Merluccius productus in the Gulf of California is carried out by shrimp trawlers. When the shrimp fishing season ends, these boats shift to catching Pacific Hake and other finfish. The Pacific Hake fishery is relatively new and has the potential to grow as an industry. Therefore,...

Reference Points for Vulnerable Fish Species Based on Bioeconomic Age-Structured Models: An Approach for Totoaba macdonaldi

Creator:: Rodríguez-García, Oswaldo Uriel, De Anda-Montañez, Juan Antonio, Valenzuela-Quiñonez, Fausto, Hernández-Flores, Alvaro, Salas-Márquez, Silvia, and María Da-Rocha, José
Abstract:: Management objectives of vulnerable fish species must focus on maintaining healthy population status. Hence, reference points should be constrained to ensure recruitment. We assessed bioeconomic reference points for the totoaba (Totoaba macdonaldi), an endemic fish to the Gulf of California, reaching lengths of 2 m and 25 years. Totoaba fishing...

Least-Cost Bycatch Reduction Through the Biodiversity Mitigation Hierarchy

Creator:: Squires, Dale and Garcia, Serge
Abstract:: The Biodiversity Impact Mitigation (BIM) hierarchy provides an overarching conservation framework for bycatch reduction, and more broadly for biodiversity conservation. This framework includes four steps, which are implemented sequentially to: (i) avoid and (ii) minimize impacts; (iii) rehabilitate/restore impacted biodiversity; and (iv), compensate such impacts, usually elsewhere. The first three steps...
