Discussion about innovation, trends and shortfalls in fisheries monitoring tends to focus on large, off-shore fisheries in New England, Alaska and the Pacific.  Those regions are home to multi-species fisheries, with complex biological interactions, and are targeted by large boats that result in sizeable discards of “non-target” fish.  Monitoring technologies, both human and electronic, are essential to reduce this waste.  Smaller scale fisheries, however, have just as much need for improved electronic monitoring and accountability measures.

Not surprisingly, blue crab is the most valuable fishery in the Chesapeake Bay.  And it’s about as complex as they come.  More than 7,000 watermen deploy small boats from thousands of waterfront access points and are regulated by three different management jurisdictions, all of which use antiquated reporting systems.

As reported on this blog before, commercial crabbers in Maryland have tested mobile technologies, like smart phones and tablets, to report and verify daily harvest.  In 2012 and 2013, volunteers used these various technologies and provided constructive feedback to Maryland’s Department of Natural Resources (MDNR) to improve its monitoring and reporting system.  Overall, participants in the two-year pilot are pleased with mobile technology tools and the web-based reporting platform, which along with dockside spot checks, have improved reporting accuracy and timeliness, according to fisheries managers.  As part of the 2013 pilot, fisheries managers offered limited regulatory flexibility for pilot volunteers in order to encourage participation and demonstrate how improved accountability can lead to streamlined regulations.

Fisheries management is principally focused on managing fishing pressure, with the goal of keeping individual fish stocks healthy enough to produce good yields.  But fisheries also affect the basic processes that keep ocean ecosystems healthy.  This is why it is important to understand how many fish need to be in the system to maintain the many important services that an ocean ecosystem can produce — including the maintenance of biodiversity, tourism value, and fisheries — and to manage fisheries so that fish populations remain at about that level.

The evidence that fish are important regulators of ecosystem processes is particularly strong in coral reefs.  The abundance and variety of fish is one of the most striking aspects of a healthy coral reef.  Some species transport energy and nutrients between seagrass meadows and the reefs.  Grazing fish species on a healthy coral reef keep seaweeds that would otherwise over-grow the reef in check.   Predators regulate populations of prey species, responding to natural variability by adjusting their feeding rates and numbers.  On a healthy reef, many different species occupy each of these niches, and each does their job in a slightly different way.  This enables the reef to resist threats and other changes (like hurricanes) and to recover from very storms or human impacts, within limits of course.

Catch Shares: Harvesting Sustainable Catches

By / Bio / Published: November 19, 2013

Originally published on November 18, 2013 on the Oceans Health Index Website

Introduction

Written by Steven Katona, Managing Director, Ocean Health Index

Maximizing sustainable food production from the ocean by harvest of wild fish stocks and production of farmed species by mariculture is one of the 10 goals evaluated by the Ocean Health Index, and it is especially closely watched because it is so critical for the future.

Three billion people out of today’s world population of 7.1 billion people depend on seafood for their daily protein and fish contribute a greater proportion of protein to the average diet than poultry.  A single serving of fish or shellfish (150 g) provides 60% of a person’s daily protein requirement, but the ocean’s continued ability to meet that need is in doubt.  Our population is rising steadily and will reach about 8 billion by 2024 and 9 billion by 2040, but the annual catch from wild ocean fisheries has stayed at about 80 million metric tons since about 1990 despite increased effort.  The reason is that too many stocks are overfished and too much productivity is sacrificed as bycatch, illegal and unregulated catch and as a result of habitat loss caused by destructive fishing practices.

Yet without increased wild harvest and augmented mariculture production, the risk of malnutrition will increase for hundreds of millions of people, because the catch will have to be shared by so many more mouths. Read More »

Setting aside space provides room for innovation

Territorial Use Rights for Fishing, or TURFs, have been in place for centuries in fishing communities around the world.  In a TURF, fishery participants have a secure, exclusive privilege to fish in a defined area.  Many fishery policy experts view TURFs and catch share programs as separate options for managing fisheries. TURFs are a type of catch share, since the area-based privileges assigned under a TURF provide the same rewards for stewardship as quota-based privileges.

In recent decades fishery managers have channeled the historical successes of this approach by formally recognizing customary TURFs, applying them to more fisheries and experimenting  with modern adaptations.

Community-based territorial rights that have existed for centuries are now formally recognized by national law in Fiji, Vanuatu, Papua New Guinea, Samoa, the Solomon Islands and Palau.  Empowered by national law promoting traditional community-based management, the Safata District of Samoa implemented a district-wide TURF in 2000.  Bylaws developed by the community manage members’ fishing efforts and limit outsiders’ access.  Safata’s leaders have further improved biological performance by establishing a network of no-take reserves.  With a formalized role in management, the district has received strong community support, high regulatory compliance and increased abundance for important species.

TURF systems have been used in different types of fisheries, but they are particularly well-suited for managing near shore fisheries where there is a clear spatial range of fishing activity. While these systems are ideal for less mobile species that don’t move beyond TURF boundaries, they can also be designed for more mobile species. Read More »

Cooperation beats competition

By / Published: November 8, 2013

By Sarah Poon

Whether in school, at work, or at play, we’ve all experienced the value of working collectively to achieve a common goal.  Many fisheries around the world are successfully managed by providing a structure for collaboration between fishermen via Cooperative catch shares.

In a Cooperative catch share, one or more groups of fishing participants, or “Cooperatives”, are allocated a secure portion of the catch or a dedicated fishing area.  In exchange, they are responsible for accepting certain management responsibilities.  Many fishing communities around the world have traditionally managed their coastal resources cooperatively, leveraging their local knowledge and relationships to achieve common goals.  Recognizing the success of this approach, many fisheries are building upon this traditional practice, while also adapting to the realities of today’s increasingly global fishery markets.

There are hundreds of Cooperatives around the world.  They have formed in different ways and have various functions and capacities.  But when it comes to their ability to manage fisheries, they share a common (perhaps obvious) theme: Cooperatives work best when people cooperate.  Cooperatives have demonstrated that fishermen working together (often hand-in-hand with fishery managers) can improve fishery science, tailor management to local conditions, increase profits and respond to complex management challenges such as discarding and habitat impacts.

Maximizing Limited Data to Improve Fishery Management

By / Published: October 30, 2013

By Ashley Apel

According to a recent study published in Science, nearly 80% of the world’s catch comes from “data-limited” fisheries.  Not surprisingly, research shows that many of these fisheries are facing collapse, jeopardizing the food security of hundreds of millions of people in developing countries who depend on seafood for a majority of their dietary protein.

Historically, fisheries with little data had few science-based management options. But new methods are being continuously developed and used in the field that deliver science-based results, even in the absence of long-term, historical catch data. Since fishery stock assessments can be extremely complex, EDF recently developed a user-friendly, six-step framework as part of an overall guide to Science-Based Management of Data-Limited Fisheries.

The framework outlines a systematic approach that fishery managers can use to conduct quick and relatively inexpensive assessments.  The methods allow stakeholders in data-limited fisheries to estimate risks to marine ecosystems, determine vulnerability of a stock to fishing pressure, calculate the level of overfishing, assess the sustainability of the fishery, and establish sustainable fishing targets and other management reference points.

Download the guide on Science-Based Management of Data-Limited Fisheries or download the entire toolkit for fisheries.  Feel free to send questions or comments to catchsharequestions@edf.org.
