Hawaiʻian fishponds or loko iʻa, are a sophisticated method for raising a steady source of food that is accessible during storms and high surf when fishing can be dangerous. Perpetuating traditional fishpond practices is important to create more sustainable food resources in Hawaiʻi and ensure that such advanced cultural knowledge is not lost
One species of squid which lives in the depths of the Pacific Ocean does not bother to distinguish male from female when mating. At the dark depths where sight is limited, male and female squid look very similar, so males will mate with and attach sperm packets to any squid of the same species. Now that’s being opportunistic.
Though it sounds like something out of a Halloween movie, ghost-fishing is actually a serious problem. Ghost-fishing occurs when abandoned or lost nets and traps continue to catch animals, leaving then to die in the nets. Ghost fishing nets are a common source of marine debris that causes the needless death of numerous marine animals. Remember to properly dispose of all your netting when fishing!
The mimic octopus is an incredible animal that can impersonate the appearance and movement patterns of a lionfish, crab, jellyfish, and many other animals. However, scientists have recently found a small jawfish whose coloration copies the mimic octopus, mimicking one of the octopus’ arms!
The Hōkūleʻa is a double hulled voyaging canoe built as a replica of the canoes that ancient Polynesians used to sail to Hawaiʻi. The Hōkūleʻa completed an amazing trip across the Pacific Ocean in 1976 without the use of modern instruments to and from Tahiti. Hōkūleʻa embarked on a trip around the world in June 2013 to share the importance of traditional knowledge, sustainability, and environmental conservation.
Photo: NOAA PIFSC In the waters off Hawaii Island, Hawaii (Big Island) marine researchers have documented fish communities in under-explored mesophotic reefs. These reef communities provide essential habitat for fish and invertebrates and may play an important role in preserving biodiversity. The depth at which these reefs exist (beyond the photic zone) may offer a “refuge” from disturbance and stress as compared to shallower reef environments. However, this depth poses a challenge for marine researchers in collecting and observing the biological communities. Until the development of... (more)
