A 3D Printer helps save New Zealand’s endangered native fish

NIWA has developed a Photarium utilizing the newest 3D printing know-how to extra safely establish and measure fish species that dwell in our waterways.

In accordance with Statistics NZ, 76 % of the 51 indigenous freshwater fish species in New Zealand are threatened with extinction or susceptible to turning into threatened, so training, knowledge and analysis are vital to understanding how higher to establish, shield and sustainably handle these species.

Photariums are indispensable instruments utilized by photographers, researchers, and educators all over the world to soundly observe dwell fish within the subject, however they’re at present solely made in the USA and don’t ship to New Zealand.

NIWA Freshwater Ecologist Peter Williams took issues into his personal palms. He developed his personal Photarium and is producing it simply and affordably utilizing a brand new industrial grade 3D printer NIWA lately acquired.

“An older 3D printer would have solely produced a prototype high quality unit and we’d have wanted a pricey specialist producer to make the completed product,” he says.

“NIWA’s new 3D printer is extra superior and permits us to provide a high quality product at low price which suggests its accessible to those that want it right here in Aotearoa.”.

A Photarium is a small plastic rectangular field, with a transparent facet and built-in ruler. It permits small fish to be studied with out being dealt with or taken out of the water. It additionally has a hinged flap to dam out mild and provides the fish privateness to scale back stress throughout transportation.

Williams designed the NIWA Photarium primarily based on his 14 years of subject expertise and has been in a position to adapt and modify it for sampling small fish species in New Zealand’s waterways.

“Lots of our native species are climbing fish and the highest a part of the lid will be closed to cease the fish from leaping out. A mesh that is printed into this hatch cowl permits us to high up the water stage for higher images,” he says.

“The great thing about the 3D printer is it permits NIWA to provide Photariums on demand and to maintain bettering our design primarily based on what we uncover whereas utilizing them within the subject.”

The NIWA Photarium improves the accuracy of fish identification. It permits assortment and launch with minimal dealing with, and with out using anaesthetics, which if not carried out correctly can result in mortality within the fish. It permits small and delicate life phases of fish to be precisely noticed and photographed with out harming the fish.

Given its success in bettering the accuracy of fish identification and images, NIWA has already had over 70 orders for its Photarium from regional councils, rūnanga, DOC, and training teams throughout the nation.

Williams can also be showcasing the advantages of the newly obtainable Photariums as a part of NIWA’s electrical fishing operator course, which he runs nationwide.
