Reproductive strategies and rockfish: A life history traits framework for fisheries management

Any trip to an aquarium or seafood market reveals the incredible variety of fishes. These fishes not only differ in how they look, but in traits related to life history. Life history traits include maximum body size, longevity, age at maturity, and fecundity – the number of eggs produced. Fishes that have the same phylogeny, or evolutionary history, share similar traits. Conversely, unrelated fishes occasionally evolve similar traits independently.

Charting A Sustainable Course: Exploring Canada’s Fisheries panel event

Nereus Program Manager Andrés Cisneros-Montemayor was a panelist at the seminar “Charting A Sustainable Course: Exploring Canada’s Fisheries” hosted by OceanCanada and the Vancouver Aquarium on April 11, 2017. The event was in the format of a casual panel discussion; the panelists provided insight on current issues and future projections for local, Indigenous, recreational and commercial fisheries in Canada.

Regulating New Fisheries: Emerging Rules for Emerging Stocks

By Richard Caddell, Nereus Program Fellow at Utrecht University

It is increasingly evident that profound changes will be necessary to current fishing practices in order to meet future global demand for seafood. Many fisheries are already operating at or beyond their ecological and economic capacity, while climate change and associated processes are projected to have significant impacts upon the future distribution of fish stocks.

Climate change could increase fishing fuel consumption

We know that fuel use contributes to climate change, but in a vicious circle, climate change could also increase fuel use in fishing. This is due to fish shifting their distributions due to warming waters. With this increased use of fuel and the increasing price, small-scale and artisanal fishers will have a harder time sustaining livelihoods and feeding their families under climate change.

Mangroves, fisheries, and community livelihoods: Conducting fieldwork in Indonesia

Mangrove forests, made up of shrubs and trees with sprawling roots that grow in salt water, provide many services to humans and marine ecosystems. They sequester carbon, pulling it from the atmosphere, and prevent erosion of coastal areas. Due to their unique characteristics, mangrove forests provide an important source of food and shelter for marine species, including many important fisheries. Mangroves cover 150,000 km² of coastline in tropical and warm temperate regions around the world. Rachel Seary, Nereus Fellow at Cambridge/UNEP-WCMC, is currently conducting research to understand both the direct benefits that mangroves have on communities living and fishing within their vicinity and also the indirect benefits that mangroves may have on coastal fisheries productivity in Bali, Indonesia.

Side Event at the UN Ocean Conference Preparatory Meeting

The Nereus Program facilitated a side event on February 16 entitled: “Co-Benefits of Achieving SDG Goal 14 to Wider SDGs: Prioritizing Action Given Climate Change and Social Inequity”. The theme of the event was implications of changing oceans on the advancement of SDG’s, with an emphasis on the co-benefits of achieving ocean targets on other environmental, economic, and social equity goals.

Managing living marine resources in a dynamic environment: The role of seasonal to decadal climate forecasts

Variations in climate lead to fluctuations and changes in fish stocks; they can have effects on such things as fish behaviour, distributions and growth. Because of this, fisheries management has to respond dynamically to these fluctuations. If management decisions are made primarily on past patterns, the negative impacts can be exacerbated, especially with climate change.
