Bonus points for using possibly the best pig graphic every published in a journal article!

People can disagree about minimum standards for MPAs, or what level of protection a given MPA should have, but bottom trawling isn’t inherently inconsistent with currently applied definitions of MPAs that allow for a range of protection levels and objectives.

Would caveat it can depend on the purpose of the MPA. e.g. some types of bottom trawling might be consistent with an MPA focused on protecting non-benthic features; It might be a minimally protected MPA, but still an MPA, e.g as defined by MPA Guide (mpa-guide.protectedplanet.net/resources)

using our model, results of hundreds of simulations of #MPA networks covering 20-40% of a seascape with multiple species varying bio-economic parameters like the amount of habitat overlap across species. ~ same size #MPA can produce wildly different outcomes depending on state of the world #30x30 🦑🌎

This image shows a plot of changes in fish catches on the y axis and fish biomass on the x axis resulting from closing 20-40% of an area in a no-take MPA. The graph shows that it is possible for MPAs to produce in terms of catch and conservation impacts "win wins", "win-lose", "lose-win", and "lose-lose" depending on the state of nature

You can check out the package at danovando.github.io/marlin/, and the paper here onlinelibrary.wiley.com/doi/10.1111/.... message me for a copy or if you have any questions. More research using the `marlin` model coming soon, and feel free to use it in your own studies! 🦑🌎

long-term data collection, statistical modeling, and subject matter expertise reveals marine heatwave as the main driver in the historic Bering Sea snow crab collapse. Impressive and important work by a great team! www.science.org/doi/10.1126/...

Introducing myself to the community over here! I'm a quantitative fisheries scientist at the Inter-American Tropical Tuna Commission. I study stock assessment (data-limited mostly), social-ecological systems, spatial management and other fun stuff. Tutorials and posts over at www.weirdfishes.blog
