State of the Environment and Conservation in the Pacific Islands: 2020 Regional Report: Indicators 13-18 - Protection of Pacific spaces
SPREP Publications, Island and Ocean Ecosystems
Available Online
2020
Pacific island countries and territories are well placed to lead in the protection of nature, with customary land tenure and vast expanses of ocean within their Exclusive Economic Zones (EEZs). Establishing protected areas has been used as a key mechanism for countries to conserve their biodiversity around the world and in the Pacific island countries and territories
Small- and large-scale eradication of invasive ?sh and ?sh parasites in freshwater systems in Norway
Island and Ocean Ecosystems, BRB

Bardal, H.

2019
In July 2016, the European Union adopted a list of invasive alien species of concern, and at present there are two freshwater ?sh species on the list. Member states are obliged to prevent further spread and to perform rapid eradication when problem species are discovered at new sites, but continental EU member states have limited experience with eradication of ?sh. Eradications are more likely to succeed if the invasive species is con?ned to insular habitats. Freshwater invasives can be regarded as island invasives, since their habitats have boundaries against shorelines, saline waters, waterfalls and dams, and these boundaries make eradications possible. CFT Legumine® containing rotenone is the only legal piscicide in the EU, and Norway has used CFT Legumine® in eradication e?orts for many years. Species that have been introduced outside their native range and have been successfully eradicated include minnow (Phoxinus phoxinus), roach (Rutilus rutilus), pike (Esox lucius), common white?sh (Coregonus lavaretus), and the salmon parasite Gyrodactylus salaris. This manuscript summarises the eradication e?orts of invasive ?sh species and ?sh parasite species during the last two decades in Norway, covering eradications from such diverse habitats as small ponds, lakes, marshlands, small streams and large rivers. An estimated £100 million has been spent in the Gyrodactylus salaris eradication programme. Costs of invasive ?sh eradications are given, ranging from less than £10,000 to more than £200,000. There are no known invasive ?sh eradication failures in Norway in the last 20 years. A summary of the e?orts in Norway can be an aid for planning control and eradication measures of invasive ?sh species in other countries.
The seward margin of Makatea, an uplifted carbonate island (Tuamotus, Central Pacific)

Montaggioni, L.F.

1987
Located at 148°15' West and 15°50' South, in the northwesternmost part of the Tuamotu archipelago (Central Pacific), Makatea island is isolated from its nearest neighbouring atolls, Rangiroa and Tikehau by about 80 km, and it is 245 km from its closest volcanic neighbour, Tahiti. This island rises at least 3,500 m above the sea floor. Like all Tuamotu islands, Makatea consists of biogenic deposits. But unlike the other islands which rise no more than a few metres above sea level and surround lagoons, Makatea reaches more than 100 m in elevation. Based on foraminiferal assemblages, age determination clearly indicated that the island frame was built up during Early Miocene (Montaggioni et al. 1985 a; Montaggioni, 1985).
Notes on the birds of Kwajalein atoll, Marshall Islands

Clapp, R.B.

1998
Kwajalein is a crescent-shaped atoll that lies between 09°25' and 08°40'N and between 166°50' and 167°45'E, near the center o£ the western (Ralik) chain of the Marshall Islands (Figure 1). Composed of more than 90 islets, largely uninhabited, Kwajalein Atoll extends about 75 miles from southeast to northwest. It has a land area of about 6 square miles (3,854 acres) (Global Associates 1987), an increase of about 263 acres over the original area that was brought about by filling of land on Kwajalein, Roi-Namur, and Meek Islands.

1997
The shorefishes of Ouvea, an isolated atoll in the Loyalty Islands group of New Caledonia, had not been surveyed prior to 1990. An extensive survey was conducted by ORSTOM between 1991 and 1992 to obtain baseline information on the shorefishes. A total of 653 taxa among 72 families are now documented from this area. The most diverse families are the Labridae (69 species), Pomacentridae (58 species), Gobiidae (54 spccies),Serranidae (39 species), Chaetodontidae (31 species) and Apogonidae (28 species). The absence or very low diversity of some families (Clupeidae, Nemipteridae, Siganidae) or genera (Abudefduf, Neopomacentrus) is similar to findings for other isolated islands of the Coral Sea. Of the 653 species recorded from Ouvea, 51 species have not been reported from New Caledonia, a large high island to the South. Only one endemic species, Luzonichthys williamsi, has been recognized among the shorefishes at Ouvea. A number of Pacific Plate endemic species were recorded at Ouvea. which is positioned on the Australasian Plate to the south of the edge of the Pacific Plate. Antennarius duescus, previously known from three specimens taken at the Hawaiian Islands, is recorded from a single specimen taken at Ouvea. Another antitropical distribution pattern is exhibited by Dinemalichthys riukiuensis, which is known to occur at Fiji, Ouvea and Queensland in the South and from Okinawa.
