Shark, ray in-country workshop for PNG fish scientists at CSIRO and JCU

Following on from earlier training, a recent in-country workshop in Australia gave two fish scientists from the University of Papua New Guinea, Port Moresby, hands on experience with leading experts at CSIRO and James Cook University (JCU).

Senior Lecturer at the School of Natural Science, Dr. Ralph Mana, and his student, William Tamarua, visited the CSIRO Australian National Fish Collection in Hobart, where they were treated to the largest shark and ray collection in the southern Hemisphere. They were given demonstrations and technical training on preparing, storing and studying chondrichthyan fish (sharks, rays, skates and sawfish).

“The scale of the collection of chondrichthyan fish was amazing,” said Dr. Mana. “It was great to see some PNG caught specimens there too, making the collection a regional one.”

Dr. Mana and Mr. Tamarua were shown the importance of properly maintaining a fish collection, and the future benefits in having good quality specimens.

“Being able to show fellow scientists how to collect biological data, curate specimens, age fish, etc., in a world-class laboratory with equipment not accessible in many countries has many benefits,” explains Dr. William White of CSIRO.

They were instructed on the process of using x-ray and high-definition photography to make taxonomic work more convincing, and to create 3D printed models for scientific study and training. The tour of the molecular laboratory showcased how specimens are prepared and their genomes sequenced, explaining the different stages of barcoding biological tissue samples.

Following the training in Hobart, the pair flew to Townsville to learn more about catching, processing and studying sharks. Hands-on training was provided by researchers at James Cook University on the best practices for preparing and observing vertebrae under a microscope to study ageing and other factors.

A standout of the visit to JCU was the Great Barrier Reef Aquarium – the largest living coral reef aquarium – demonstrating the water filtration system, coral growth garden, and wide array of tropical fish.

“These in-country workshops highlight the importance of a network of collaborators from various institutions,” said White. “In this case, CSIRO provided the taxonomic and genetic training while JCU provided the ecological and biological training.”

“All in all, what I was exposed to was more than I expected. The several days I spent at Hobart and Townsville was truly educational and enlightening particularly in sharks research and conservation work. It provides a new stepping stone for me to continue the cooperation I have established with William and Andrew,” concluded Mana.

The in-country workshop is furthering the work of a large-scale ACIAR project on Papua New Guinea’s shark fisheries, which aims to improve capacity of ecological, socioeconomic and stock assessment aspects of fisheries management.

At our recent Doing Well by Doing Good Forum in Hobart, a presentation was given on the range of training that the Fund’s Tasmanian Committee has supported around capacity development in fisheries.
