Descrição

A total of 104 fish and 24 coral (Scleractinia, Zoanthidea, Corallimorpharia, Milleporina) species were identified in the area of Papeete harbour (Tahiti, French Polynesia). This overall richness is comparable to less-disturbed fringing reefs around high volcanic islands in the Society Archipelago. Human activities reduced species richness slightly in inner areas of the harbor. Two passes, which connect the harbor to the open ocean, renew lagoonal waters in the inner harbor at a rate that appears sufficient to minimize effects of human disturbance.

Métodos de Amostragem

Eight stations were established in the study area. Stations F3, F4, F5, and F6 were located in the inner part of the harbor, whereas stations F1, F2, F7 and F8 were located at its margin. A station was defined as an area of approximately 250 m2 (10 x 25), starting from the shore down to a depth of 5 m.

Área de Estudo With approximately 93,000 inhabitants, the city of Papeete and its suburbs are by far the most populated area in French Polynesia. Papeete harbor was built on both sides of a deep channel connecting Papeete pass and Taunoa pass. The ocean side of the harbor was built by extension of a small islet (Motu Uta), and is connected to the island side by Fare Ute Bridge. The island side of the harbor is adjacent to the city center. In operation since the end of the 19"' century, the harbor was subjected to extensive construction and development during the 1960's. This development persisted into the 1980's with total freight traffic increasing from 600,000 tons in 1977 to 1 million tons in 1987

Descrição dos passos do método:

  1. At each station, one qualitative survey (presence/absence) of fishes was made by Planes by snorkeling or diving during a 60-minute period of observation on the area covered by the station. The same method (i.e., 60-minute period of observation) was used by Adjeroud for the qualitative survey of anthozoans (including hard and soft corals and Millepora, herein classified as corals). Qualitative surveys were made in August 1995 (dry season). Surveys of surface-water quality characteristics at the same eight stations were made once a year at the beginning of the rainy season (November) from 1990 to 1995 by the Laboratoire d'Etudes et de Surveillance de l'Environnement (LESE). Temperature, salinity, pH, and dissolved oxygen were measured using in situ probes. Surface-water samples were collected for measurement of suspended matter, nutrients (NH4, NO2, No3, P04, SO2), and heavy metals (Fe, Cu, Zn).
