Fishery Improvement Projects FIPs are multi-stakeholder initiatives that help fisheries work towards sustainability. FIP accreditation is necessary for premium price vendors like SmartFish Mexico supporting fair trade for fishers. Webinar tomorrow Pronatura Noroeste on strengthening FIP governance.

Strengthening #Vaquita community monitoring program a focus of 2025 survey "Continued investment & more training can go far in creating a dedicated team to continue vaquita observations & build community knowledge & enthusiasm for saving the vaquita & preserving marine ecosystem"

Today @Cites #SC79 requested Mexico to fully achieve & report on its #vaquita #totoaba action plan to #SC81 (approx 1 year). US amendment for Secretariat to consider relevant info from other sources unnecessary as @Ben_J_v_R confirmed that Sec does so without explicit mention.
November 23, 2025 at 2:48 PM
Mexico achieved most of its stated goals in its #vaquita #totoaba compliance action plan & Nov 23 @CITES #SC79 will decide a deadline. Alternative gear part is the most incomplete & challenging, but progress includes @IMIPASmex test plan for @pescaabc modified shrimp small trawl.

1/2 Nifty tech: #vaquita survey lead drone pilot @FabianRguez94 flew with adapted LIDAR altimeter at precisely vertical position above the #vaquitas they spotted; calibrated equation converts pixel length into real distance; length & girth estimated for assessing age & condition.

1/3 Before @CITES #SC79, new CAT report analyzing @SeaShepherdSSCS counts of fishing skiffs on its ship radar in 4 parts of #Vaquita Refuge - ZTA Zero Tolerance Area, its EXTension (both with anti-gillnet devices), its Buffer Zone & nearby VRA area visible on 8 naut mile range
November 18, 2025 at 8:17 PM
At @CITES #COP20 Mexico will be requested to "effectively prevent fishers from using gillnets in the #Vaquita Refuge & vessels from entering the Zero Tolerance Area & maintain these areas completely gillnet-free" but this won't happen without real change in fishing gear & markets

Good long read on 2025 #vaquita survey results, context & implications
Exciting sighting of "a mother & calf close enough to see with the naked eye, doesn’t happen very often as they’re really, really difficult to see. If there’s any swell they just disappear. Plus, there's only a few of them left"

A first in #vaquita habitat, making progress for environmental education - some of the crafts & souvenirs made from recycled fishing nets & beach cleanup plastic trash in the Upper Gulf, supported by CONANP, Pronatura Noroeste & Pesca ABC

1/3 Amazing @nmas #vaquita retrospective with film from 30 years ago, interviewing Caterina D'Agrosa, lead researcher on the only study to properly quantify the level of gillnet bycatch. Entanglement was all too common, & fishers were willing to bring the carcasses back to her.

Viral video is one of dozens of Upper Gulf fishers making new shrimp gillnets. It's illegal to make them & use them, but because everyone is doing it, no one is punished. And they shouldn't be, they obviously are not criminals & not seeking to cause harm to #vaquita. Solution ⬇️

It's encouraging to see Upper Gulf #vaquita safe fishing gear & policy high on CONAPESCA Commissioner's agenda & joint work with SEMARNAT

The extensive acoustic monitoring efforts of the summer of 2025 leave no doubt that #vaquita now occur well north of the ZTA in the Refuge, but during the visual survey there were only two days with optimal calm Beaufort conditions for searches there & none were seen

Summer 2025 had more acoustic monitoring effort for the #vaquita porpoise than any other season in the entire 15 year history of this pioneering program developed & led by CONANP Mexican scientists supported by technical field skills of San Felipe fishers including Pesca ABC.
