This is a collection of reports and papers that were used to develop the Framework for Integrated and Habitat Evaluation (FISHE), as well as a selection of supporting materials that can be used during the eleven steps of the data-limited framework.

This manual deals with the practical implementation of routine data collection and monitoring programmes. The data collection and monitoring programme is developed through a top-down approach, from the identification of the objectives down to the practical recording and management of data obtained from the fishery. The issues are dealt with both through detailed discussion and by using simple examples. The examples are mostly based on situations in tropical fisheries, and in particular, experience has been drawn from developing a data collection programme in Viet Nam. The main questions addressed in the manual are which fisheries data to collect, where and when to collect them.

The Method Matrix contains all the assessment methods presented within the FISHE process. It can help you determine which methods can be done with which types of data and can suggest areas to focus additional data collection efforts in order to expand the methods that will be available to you.
This is the "paper" version of the Method Matrix. You will find all of the assessment methods included at Steps 1, 3, and 4 of FISHE on its first page, and all of the Step 5 and 9 methods on its second page. Pages 3, 4, and 5 provide “zoomed in” views of the Page 2 methods, one management question at a time.
On each page, methods are listed across the top of the table while data streams are listed down the left side. Above the methods you'll find examples of management questions that the methods can help answer (which are further broken down into specific management-relevant information on Pages 1, 3, 4, and 5).
Within the tables, checkmarks indicate which types of data are needed to conduct each method. Some methods can substitute one type of data for another, so in some cases a method may have checkmarks next to two types of data when one or the other will suffice. Additionally, some methods can help answer additional questions with additional data. These “nice to have” data are indicated with purple check marks. For more information and further clarity, be sure to read the information provided for each method in the corresponding step of the FISHE framework.

Authors present mizer, an R package for implementing dynamic size spectrum ecological models of an entire aquatic community subject to fishing. Multiple fishing gears can be defined and fishing mortality can change through time making it possible to simulate a range of exploitation strategies and management options.

This worksheet is an offline version of the MPA Density Ratio calculator provided on this site. No-take marine protected areas (MPAs) and other well-enforced reference areas provide excellent baselines against which to compare fished stocks. Fish densities (measured in kg/ha) inside and outside the MPA can be estimated from the results of fishing or visual surveys. The MPA Density Ratio (fished/unfished fish density) can then be calculated to serve as an indicator of stock status.

In many fisheries, fishermen innovate actively to increase their catch by adding new technologies like fish finders or inventing new gears and fishing practices. If your fishery is like this, you should adjust fishing effort estimates accordingly because catch per unit of effort like hours at sea or soak time of the gear will likely increase over time because of these innovations. You can either estimate the rate of innovation that increases catch per unit effort directly yourself, or use the simple model included in this paper to estimate it. The model is based on empirical observations of the rate of technological creep in many fisheries around the world, mostly industrialized temperate water fisheries but including some tropical small-scale fisheries.
