Coral Reefs: Fishing for Sustainability

Sustainable fisheries must ultimately reduce poverty while maintaining ecosystem productivity. On coral reefs, managing for 'concave' trophic pyramids might be a win-win for people and ecosystems, by providing higher-value fisheries and maintaining important ecological functions.

Ecological Studies of Black Coral in Hawaii!

TABLE 1 readily be made and the factors limiting distribution could be outlined. Branches of the living colonies were transplanted to various habitats, where regular observations could be made to determine if the animal was alive, dying, or dead. These transplants were put in places where it was hoped the effects of environmental extremes could be discovered . For example, the headland off Moku...

Effects of sewage discharge, fishing pressure and habitat complexity on coral ecosystems and reef fishes in Hawaii

The major factor controlling the abundance of reef fishes in Hawaii (USA) appears to be habltat complexity (bottom topographic relief and interstitial space) Fishes aggregate In areas of h ~ g h hab~tat complexity at b~o~nass levels whlch, in areas protected from fishing, may significantly (by 2 to 5 times) exceed levels supported by pnmary production within the ecosystem. High relief natural a...

Acoustic properties of coral sands, Waikiki, Hawaii

An in situ experimental study of variations of compressional wave speed and attenuation with depth in natural coral sands has been made offshore of Oahu, Hawaii. In situ data were collected at a center frequency of 7.5 kHz. Compressional wave speed averages around 1620 m/s and attenuation ~expressed as Qp , the reciprocal of the quality factor! decreases from 0.04 at the seafloor to 0.01 at 2 m...
