This study develops critical reference points for sustainable management by using a large empirical dataset on the coral reefs of the western Indian Ocean to investigate associations between levels of target fish biomass (as an indicator of fishing intensity) and eight metrics of ecosystem state. These findings provide tangible management targets for multispecies coral reef fisheries and highlight key tradeoffs required to achieve different fisheries and conservation goals.
A how-to guide for data collection and monitoring in nearshore finfish fisheries.
Document summarizing all of the inputs necessary for, outputs generated by, and assumptions inherent in each of the assessment methods presented on the FISHE website.
- 24.Depletion-based stock reduction analysis: a catch-based method for determining sustainable yields for data-poor fish stocks
We describe a method for determining reasonable yield and management reference points for data-poor fisheries in cases where approximate catches are known from the beginning of exploitation. The method, called Depletion-Based Stock Reduction Analysis (DB-SRA), merges stochastic Stock-Reduction Analysis with Depletion-Corrected Average Catch. The method produces probability distributions of management reference points concerning yield and biomass.
- 25.Depletion-corrected average catch: a simple formula for estimating sustainable yields in data-poor situations
The depletion-corrected average catch (DCAC) formula is an extension of the potential-yield formula, and it provides useful estimates of sustainable yield for data-poor fisheries on long-lived species. Over an extended period (e.g. a decade or more), the catch is divided into a sustainable yield component and an unsustainable “windfall” component associated with a one-time reduction in stock biomass.
- 26.Developing new approaches to global stock status assessment and fishery production potential of the seas
FAO report in two parts. Part 1 focuses on determining single-stock status and summarizes the results of simulation testing of four methods that can be applied to data-poor fisheries. Part 2 reports the results on the estimation of ecosystem-level production potentials based on satellite-based estimates of primary productivity.
Includes details on the modification of Catch-MSY method into CMSY method.
We developed an approach to progress the [ecosystem-based fisheries management] EBFM mandate in Australia, using a new ecological risk assessment framework applied to fisheries, termed Ecological Risk Assessment for the Effects of Fishing (ERAEF). Novel features of this framework include its hierarchical structure and its precautionary approach to uncertainty. The amount of information required increases through the hierarchy, and allows application in data-limited situations.
Coral reefs are ecosystems with documented fishing thresholds. Fisheries in these systems can thus be managed to remain above these limits, reducing the risk of system collapse. Use the calculator in this worksheet to determine the fish biomass ratio (kilograms/hectare) of your coral reef system and compare with the ratios for the Indian Ocean and Caribbean Sea in the tables provided.
Peer reviewed paper presenting boosted regression tree model, which correlates depletion with a range of predictors calculated from catch data in order to improve depletion estimates.
