NZ deep Water fish species
In just seven days of ocean sampling research near the Kermadec Islands northeast of New Zealand, scientists found several strange-looking species of deep sea fish that were rare, new to science or never before seen in the area.
The scientists from University of Aberdeen’s Oceanlab, the National Institute of Water and Atmospheric Research, and Museum of New Zealand Te Papa Tongarewa explored the Kermadec Trench, which goes down more than six miles and is one of the deepest places on Earth, according to the university website.
Here are a few of their discoveries:
- a new species of eelpout at depths of 4250m
- new depth records of 5, 500m for a rattail fish – these have not previously been caught in the southwest Pacific
- another rattail fish – in depths of between 2000 and 4500m – that has not been caught in New Zealand waters for over 100 years
- new depth records of 3500m for large deep sea cusk eels
Researchers also noted the accomplishment of actually being able to conduct sound reviews of what is at deeper parts of the ocean due to new technologies.
“A voyage such as this is testament to how feasible scientific research in the deep sea has become, ” Jamieson said in a statement. ”It is no longer the inaccessible, out of reach, part of the world it once was. The technological challenges of the past are being overcome, and shouldn’t limit our responsibility to learn about and understand the deep sea to help ensure the long term health of the deep oceans – one of the largest environments on Earth.”

Hearing fishermen's pleas, Uye, who had been studying zooplankton, became obsessed with the little-studied Nomura's jellyfish, scientifically known as Nemopilema nomurai, which at its biggest looks like a giant mushroom trailing dozens of noodle-like tentacles.
"No one knew their life cycle, where they came from, where they reproduced," said Uye, 59. "This jellyfish was like an alien."
He artificially bred Nomura's jellyfish in his Hiroshima University lab, learning about their life cycle, growth rates and feeding habits. He traveled by ferry between China to Japan this year to confirm they were riding currents to Japanese waters

“This allows the predator fish to feed heavily on the forage fish species. Consequently, the predator fish species are fatter and healthier during the next years spawning season,” she explained.
