“…3 Thus, the current situation has raised two major issues: first, an economic issue because the price of fish meal has tremendously increased over recent years and, second, an environmental issue due to overfishing risks associated with fish meal production. 4,5 To develop a more sustainable aquaculture, there is currently a trend toward the development of low FM−FO feeds for almost all species of farmed fish and shrimp. These feeds are based on plant ingredients and allow therefore a significant decrease in the use of fish meal.…”

Two forms of selenium (Se) supplementation of fish feeds were compared in two different basal diets. A 12-week feeding trial was performed with rainbow trout fry using either a plant-based or a fish meal-based diet. Se yeast and selenite were used for Se supplementation. Total Se and Se speciation were determined in both diets and whole body of trout fry using inductively coupled plasma mass spectrometry (ICP MS) and high-performance liquid chromatography (HPLC). The two selenoamino acids, selenomethionine (SeMet) and selenocysteine (SeCys), were determined in whole body of fry after enzymatic digestion using protease type XIV with a prior derivatization step in the case of SeCys. The plant-based basal diet was found to have a much lower total Se than the fish meal-based basal diet with concentrations of 496 and 1222 μg(Se) kg(-1), respectively. Dietary Se yeast had a higher ability to raise whole body Se compared to selenite. SeMet concentration in the fry was increased only in the case of Se yeast supplementation, whereas SeCys levels were similar at the end of the feeding trial for both Se supplemented forms. The results show that the fate of dietary Se in fry is highly dependent on the form brought through supplementation and that a plant-based diet clearly benefits from Se supplementation.

“…Similarly, while Acadian redfish have been rebuilt and are currently locally abundant, this fishery has a history of collapse and life history characteristics that make it vulnerable to overfishing (Mayo 1998). Therefore, creating markets for species that are currently locally abundant creates a risk of contributing to future collapse (Lobo et al 2010). …”

The development of local food markets has provided a critical economic opportunity for small farms in New England. The collapse of Gulf of Maine groundfish stocks has motivated an interest in developing similar marketing opportunities for wild-caught, locally abundant seafood. Institutions, particularly schools and colleges, have been identified as a strategic entry point in the supply chain for such products. However, there has been a dearth of research on this topic. We undertake a case study that evaluates purchases of local groundfish by schools and colleges in New England. First, we analyze recently developed secondary data to assess the propensity and frequency of local seafood purchases. We find that local seafood purchases by schools in New England are not widespread even among the subset of schools that are undertaking farm to school activities, and that schools that are purchasing local seafood are doing so infrequently. We also find that colleges have been more proactive in sourcing local seafood products. There is a high degree of state-level variation within New England, as institutions in states with relatively more prominent commercial fishing sectors are sourcing local seafood products to a relatively greater degree. Further, colleges explicitly expressed that technical assistance in sourcing sustainable seafood products would be most beneficial in regions where there was less available supply. Second, to draw further inferences about the sustainability of local seafood purchases, we report the results of seafood procurement procedures from New England colleges. We find that these colleges source a wide variety of local groundfish principally for on-campus dining and that they place high value on seafood certification schemes as guidance for making sustainable purchases. We conclude by reviewing how data collection methods for local agricultural markets could be modified with regard to seafood distribution systems.

Recent studies have documented that watersheds of terrestrial protected areas benefit adjacent aquatic ecosystems and fisheries (Abraham & Kelkar ), thus highlighting the need for evaluating protected areas as functional landscapes, in addition to their role in biodiversity protection.…”

Summary1. India, a mega-diverse country in terms of both biodiversity and people, is battling environmental problems on many fronts: chronic dependence on natural resources, dwindling ecosystem services, declining environmental quality, effects of climate change and a biodiversity crisis. 2. We review the current focal areas and infrastructure for ecological research and education in India, along with the surrounding legal and policy aspects of related socio-economic issues. 3. Currently, ecological and applied research is predominantly focused on charismatic species within protected areas. This scope could be broadened beyond organismal biology towards functional landscapes and ecosystems; the education system also needs to promote ecology as a career choice for scientists. Expectedly, many environmental challenges are generic in nature, occur in other regions of the world, are primarily biophysical in origin but extend into human dimensions; some challenges are socio-political and have implications for biodiversity conservation. 4. Synthesis and applications. India's environmental concerns include, but are not restricted to, the biodiversity crisis. The biodiversity crisis, in turn, includes, but is not restricted to, the most charismatic species. Greater integration and alignment among the mandates of government agencies, scientists, policymakers and educators are needed to meet contemporary environmental issues.
