Sexselective fisheries

Males of many coral reef fish species tend to be preferred due to their distinctive coloration. Male mandarinfish, Synchiropussplendidus, for example, bear attractive dorsal fins and displays170. Male wrasses, such as the bird wrasse Gomphosus varius, and the sapphire devil Chrysiptera cyanea, are also often preferred to plain-looking females37. Such brightly coloured specimens are also likely to fetch higher prices on the market. Selectively harvesting for males of particular populations on a...

The SMART project

The South Pacific Forum Secretariat, together with the Marine Aquarium Council, has started a programme to implement marine ornamentals certification within the South Pacific Region. It will focus primarily on the islands of Fiji, the Cook Islands and the Solomon Islands and will address the negative impacts the ornamentals industry presently has or may have. It will also introduce market-driven third-party certification for established operators to ensure sustainable development of the...

Invasive Species

The introduction of aquarium fish species to areas where they do not occur naturally is a problem more acute for freshwater species than for marine species. Reports have indicated that a number of individuals of the species Pterois volitans, lionfish (marine fish native to the Indo-Pacific region), have been observed on four wrecks and one natural hard bottom off the coast of North Carolina at depth ranges between 40 and 45 m during 2000 and Some individuals were also observed off the include...

Corals

Mariculture can be an environmentally sound way to increase the supply of hard and soft corals, and has proved successful for a large number of species. In light Finger leather cabbage coral, Lobophytum spp. Finger leather cabbage coral, Lobophytum spp. of this, coral aquaculture is increasingly mentioned as a priority solution for reducing the harvest pressures on coral reefs190. An additional advantage is that cultured coral is acknowledged as adapting better to aquarium conditions than...

The threespot dascyllus, Dascyiius trimaculatus. EC Annex D data show that 106,662 seahorses were reported as imported into the EU between 1997 and 2001. GMAD data for this period show a total of 20,477 seahorses reported as imported into EU countries (or 24,647 specimens between 1996 and 2002)....

Impacts On Populations

Most traders argue that the collection of marine ornamentals for the aquarium trade has no negative impact on reef fish populations. This is likely to be true for fisheries that are fairly small in comparison to the available resource base (fish population). A study in the Cook Islands showed that the total catch per unit effort remained constant between 1990 and 1994114, an indicator that fish populations on these islands were probably being harvested sustainably. In Australia, through the use...

Life histories

While a huge diversity of species is demanded for the aquarium trade, a large part of the trade tends to be centred on individual species. These species' vulnerability to collection will depend on a number of life history parameters, in particular growth, reproduction and recruitment54. Overall, there is very little information available on the life history characteristics, growth rate or reproduction mode of most coral genera in trade. Environmental conditions influencing individual corals...

Size limits

Size limits are another useful tool in managing aquarium fisheries. The marine ornamental fish trade tends to be highly selective in favour of juveniles due to their distinctive coloration, low transport cost for exporters and optimal size to fit in a home aquarium. However, the young of some popular fish species are easily stressed and hence may suffer high mortality during holding and transport6. Setting minimum size limits such as those encouraged by an Ocean Voice International-Haribon...

Live rock

Tectus Spp Turbo Spp

CITES defines live rock as 'pieces of coral rock to which are attached live specimens of invertebrate species and coralline algae not included in the CITES Appendices and which are transported moist, but not in water, in crates71. Typical inhabitants of live rock are anemones, tunicates, bryozoa, octocorals, sponges, echinoids, molluscs, sabellarid and serpulid tubeworms, and calcareous algae. Besides the aesthetic role live rock plays in aquaria, the organisms which live in live rock, through...

Giant clams

Giant clams represent an increasingly large proportion of the exports of live invertebrates destined as aquarium specimens. Although additional lighting is often required in order to maintain giant clams, they play an important role in removing nitrates, nitrites and ammonia from aquaria water, elements considered as The most commonly imported sea star in the aquarium trade is Linckia laevigata. According to exporters' data within GMAD this species accounted for 3 per cent 32,509 pieces of the...

Executive summary

Species Surgeonfish Asia

Between 1.5 and 2 million people worldwide are believed to keep marine aquaria. The trade which supplies this hobby with live marine animals is a global multi-million dollar industry, worth an estimated US 200-330 million annually, and operating throughout the tropics. Ornamental marine species corals, other invertebrates and fish are collected and transported mainly from Southeast Asia, but also increasingly from several island nations in the Indian and Pacific Oceans, to consumers in the main...

Figure 5 Top three importers of live and wildsourced clams

Totals are derived from importers' data. Several source countries have also implemented legislation to better manage and protect their giant clam stocks. In 1996, the Philippines, previously dominating exports for the international shell trade and one of the main suppliers of live clams for the international aquarium trade, adopted a total prohibition on all exports of giant clam82. The Solomon Islands reported that only exports of cultured giant clams were allowed, while with help from the...

Soft corals and sea fans

Broccoli Coral

Most of the soft corals in trade originate from the Indo-Pacific Ocean. Although soft coral farming is considered to be simple and straightforward70, very few specimens are of cultured origin. American Samoa represents an exception52. Despite high numbers of specimens being traded for use in aquaria, soft corals are not, unlike stony corals, covered under CITES54. No mechanisms other than GMAD exist to monitor quantity, origin and destination of species in trade. GMAD data indicate that a total...

The mandarinfish Synchiropus splendidus

Extremely limited scientific information, particularly on its biology and fishery, is available for the small, benthic dragonet of the Western Pacific. All individuals traded for the aquarium industry are taken from the wild and the impact of heavy collection 21,458 individuals based on importers' data or 11,168 individuals based on exporters' data in GMAD, traded within the EU only on fish populations is unknown. It is subject to a sex-selective fishery up to 70 per cent of fish caught are...

Analysis of trade data

The following section will describe analyses of CITES data for trade in stony corals and giant clams, Annex D data for seahorses and GMAD data for fish, corals and invertebrates. Based on sales data supplied by the 58 companies in GMAD and applying the method described in Green8 the best estimate of annual global trade is between 20 million and 24 million for marine ornamental fish, 11-12 million for corals and 910 million for marine ornamental invertebrates. Records within GMAD for marine...

The scribbled angelfish Chaetodontoplus duboulayi

Anecdotal information has suggested that some populations of the scribbled angelfish Chaetodontoplus duboulayi, pictured may be depleted. Although this information has not as yet been validated by scientific surveys, local fishers in Queensland, Australia, have observed significant fluctuations in population densities over the years and thus have raised concerns. Population estimates between the Keppel Island group and the southern extent of the species in Hervey Bay, Australia, show lower...

Invertebrates

Since technical constraints regarding the spawning of mature giant clams and raising of larvae and juveniles were overcome in the 1980s, interest in giant clam culture and population management has increased considerably84. Giant clam mariculture has several advantages the animals require no artificial feeding, rearing techniques are relatively simple and the setting up of facilities requires little capital investment and can involve local community members. Furthermore, unlike many other forms...
