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

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
