FISH IN THE SEA

Deep Sea Fish
Students are shown photos of various weird deep-sea fish as they hear about their general characteristics, including feeding and reproductive habits typical of animals in the deep sea.
The students will make a list of important characteristics that they think would be useful to classify fish.
A discussion is held about limitations and benefits of traits and adaptations found in deep-sea fish, followed by the students working in small groups to create their own deep-sea fish based upon what they have learned so far.
Each group presents their animal to the rest of the class, explaining the function and need for each body part or organ placed on the animal.
Extensions can be incorporated for any grade level.
See "Beyond the Activity", below.
However, animals recently discovered in the deep sea are known to live under very extreme conditions, including darkness, high pressure, and drastic temperature changes.
On the ocean floor, hot fluids released from the hydrovents can reach 750 degrees Fahrenheit.
In addition, little sunlight, if any, reaches beyond 3, 000 feet; no wavelengths can be absorbed, and the world is dark.
Consequently, deep sea fish and other animals have acquired adaptations that allow them to "create" their own light, a process called bioluminescence.

IRC | "There\'s a Lot of Fish in the Sea, " and IRC Helps Aceh Fishing Communities Catch Them
The income from these traditional vessels, called palong, is expected to indirectly benefit several hundred people in areas that were completely destroyed in 2004.
The IRC field office in Banda Aceh, Aceh's capital, organized the construction of the platforms and contributed all materials and equipment.
Darmi Yunus, a team leader for the IRC's community-driven regeneration program in Aceh, says the platforms will radically improve the lives of people who have had little opportunity to earn a living since the tsunami.
'Fifty percent of the income from the fish goes to the crew on the platform, ' Yunus explains.
'The rest is put in a village fund, intended for various community projects and unforeseen expenses.' The palong is pulled out to sea by a smaller boat each evening and the crew use strong lamps to attract fish into large nets.
As dawn breaks, the catch is brought to shore in small boats and handed over to the fishmongers.
'We catch about 30 big baskets of fish and shrimp every night, ' says Muslim, who is the chief on one of the platforms anchored off Layeun, a small fishing village.
'On average we make about eight million rupiah ($900) each week.' Like many fishermen along the ravaged coast, Muslim, who uses only one name, lost his boat and livelihood in the disaster.

The researchers say many other species are likely to be similarly endangered and, worse, there seems little hope of saving them.
Most commercial fish, such as cod, live on the continental shelves.
But overfishing in the 1970s led fishing vessels to move on to a hitherto-unexploited wealth of strange-looking fish on the slopes of the continental shelves, down to 1600 metres..
