Turtles of Aotearoa

Turtles of Aotearoa 7 species of sea turtle in the world 5 recorded in New Zealand 2 more frequently seen here Nearest nest sites in Australia and New Caledonia Navigate using earths magnetic field Forage near the coast eating algae and sea slugs Threatened with extinction, dying here from marine plastic boat strike and fishing The regional subpopulation is expected to go extinct in 40-80 years Nest in Papua New Guinea, and Solomon Islands Forage offshore on jellies in the water Frequently caught by tuna fishers, with no efforts to reduce bycatch in leatherback hotspots Up to 1.5 m long Up to 2.7 m long Green sea turtles Leatherback sea turtles Loggerhead Green Leatherback Olive Ridley Hawksbill

After finding a green sea turtle in Devonport and reading about leatherback sea turtle bycatch I decided to do some research on what was going on with turtles in New Zealand. I made a graphic summary.

Changes in reporting for inshore fishing boats with cameras

There is some confusion about the change in these numbers because of the way the data was reported. I made this graphic to also clear up that as of April 2024 there is no data that has been made public from the on-board cameras for commercial fishing vessels programme.

New Zealand’s dairy industry

New Zealand dairy industry

Environmental reports and main stream media are often critical of different aspects of the New Zealand dairy industry. Here I summarise them together in one graphic. View at higher resolution by clicking on the image below.

More experiments with AI generated art. I used multiple tools all built on Stable Diffusion, however I am still refining everything in Procreate and compositing with Photoshop.

Bottom trawling graphics

I recently took part in a science led process to limit the impacts of bottom trawling & Danish seining in the Hauraki Gulf Marine Park. I found the narrow scope of the work quite frustrating. The fishing industry knows it has a social license issue with bottom trawling and made a video to address it. The cartoons don’t tackle key concerns with the fishing method. I have made some graphics to point out the key issues focusing on the smaller (<20m) bottom trawlers that scrape the seafloor of the Hauraki Gulf Marine Park.

Bottom trawling is a problem for much of New Zealand’s EEZ and beyond. Feel free to download and use the graphics, let me know if you want them at a higher resolution.

Calculation: 7,658 Trawls 2016-19. 7,658*13.5km (12-15km per trawl) = 103,383kms / 3years = 34,461kms PA. Length of NZ = 1,600km. 34,461km / 1,600km = 21.5. 21 times the length of Aotearoa.
Management Action 1.1.1 in the draft Fisheries Management Plan promised to “Exclude bottom trawling and Danish seining from the Hauraki Gulf Marine Park (HGMP). Designate corridors suitable for bottom trawling and Danish seining and create exemptions from the ban for these corridors.” This has been changed to “Exclude bottom trawling and Danish seining from the Hauraki Gulf except within defined areas or ‘corridors’.”
