International trade in live, ornamental "fish" in the US & Florida

The importance of international markets as a source of live, ornamental “fish” supply is growing due to more stringent wild-harvest regulations in Florida. In addition, foreign markets are increasing in importance as a source of demand for Florida purveyors of live, ornamental “fish”. Florida plays an important role in this growing international market. Trends in imports and exports of live, ornamental “fish” are described for two primary data sets: U.S. Customs and U.S. Fish and Wildlife Service. These trends are described primarily for the 1994-98 period for Florida and the United States. Florida imports and exports are described for the two major ports: Miami and Tampa. The most important trading countries are also described. This information will help Florida purveyors of live, ornamental “fish” better understand the international markets upon which they have become more dependent. (PDF has 18 pages)

The Indonesian ornamental fish trade: case studies and options for improving livelihoods while promoting sustainability in Banggai and Banyuwangi

The four main objectives of this case study are: 1. Understanding market chains: an overview of the market chain from Indonesian reefs to international retail, with greater detail for case study sites. 2. Identifying poor people in the market chains: including people involved in the chain of custody and others who may be indirectly involved or impacted. 3. Understanding the influence of the marine ornamentals trade on the livelihoods of poor people: the case study looks specifically for underlying as well as obvious factors contributing to poverty reduction, and identify examples of better practice for poverty reduction in the marine ornamentals trade, including examples of positive livelihood outcomes from participation of poor people. 4. Identifying recommendations to improve poor people’s livelihoods. (PDF contains 286 pages)

Conservation and sustainable utilization of Nigerian ornamental fishes

The paper assessed qualitatively the threat status of nigerian freshwater fishes that are presently being exported and those that have potential in aquarium trade using such criteria as rarity, size at maturity, mode of reproduction, human population density, habitat degradation, pollution and range of each species among others. For their conservation captive breeding of these fishes were proffered with information that can assist collectors, exporter and aquaculturists that wants to breed polypterids, Butterfly fish, Knife fish, Elephantfish, Pollymyrus isidori, Arnordichthys spilopterus, Nannaethiops unitaeniatus, Killifishes, Polycentropsis abbreviatta, Cichlids, Ctenpomas, Mastacembelids and Tetraodon lineatus

Export potential of ornamental live fishes in Nigeria

Nigeria is blessed with an abundant variety of fish species, some of which have been exported over the years. These fish species are taken either from the wild or cultured. Large quantities of fishes and fishery products are exported from Nigeria in different forms and which have been sources of foreign exchange earnings for the Country. An estimate value of exports in the fishery sub-sector stood at approximately U.S. $48.212,070 for shrimps/sole fish/cuttlefish/crabs and over U.S.$500,000 for ornamental live fishes

Low cost light traps for coral reef fishery research and sustainable ornamental fisheries

Two relatively inexpensive light traps to capture pre-settling reef fish and invertebrates are described. A trap made from a plastic bucket (with plastic bottles, a small plastic waste bin and two sheets of plywood) that costs US$15 appears to be just as effective as a large aluminium and plexiglass trap that costs US$275.

Ornamental fish resources of Manipur: potentials, problems and strategies for development

The study revealed 125 species of fishes in Manipur of which 95 species belonging to 48 genera and 22 families have ornamental value. Fifty percent of these belonged to the family Cyprinidae, 7% to Cobitidae, 5% to Sisoridae 7% to Balitoridae, 3% to Channidae, 8% to Bagridae, 2% each to Chandidae and Mastacembelidae. Species representation in other families (16%) includes 1.6% each in Belonidae, Nandidae, Notopteridae, Psilorhynchidae, Schilbeidae and 0.8% each in Amblydpitidae, Anabantidae, Aplocheilidae, Belonidae,Chacidae, Clupeidae, Mugilidae, Symbranchidae, Siluridae and Tetradontidae. The conservation status of fishes showed that 25.6% of them have not been evaluated, 21.6% are vulnerable, 16.0% are endangered and 2.4% are critically endangered. "Low risk near threatened" category amounted to 25.6% and only 6.4% in "low risk least concern" category. Hence a cautious and regulated approach needs to be adopted while promoting ornamental fish trade. Suitable strategies for developing a viable ornamental fish trade in the state are discussed.

Effects of dietary supplementation of commercial human probiotic and antibiotic on the growth rate and content of intestinal microflora in ornamental fishes

The effects of dietary supplementation of commercial human probiotic, Lactobacil and antibiotic, oxytetracycline on the growth, survival, disease resistance and content of intestinal microflora in two ornamental fishes, viz., goldfish, Carassius auratus and swordtail, Xiphophorus helleri were studied. The total wet weight gain, food conversion ratio and specific growth rate of C. auratus did not vary significantly (p>0.05) among treatments. While in X. helleri, significant differences existed in the total wet weight gain, survival, food conversion ratio and specific growth rate among treatment groups (p<0.05). The counts of antibiotic resistant bacteria in fish gut increased with days of culture in all the treatments and the increase was more in antibiotic fed fishes. A reduction in the development of antibiotic resistance among the bacterial flora of fish gut was noticed in probiotic fed groups of C auratus and X. helleri. The results of the present study revealed that the effects of human probiotic on the growth, survival and disease resistance of ornamental fishes are variable and difficult to reproduce the similar effect on different species.

A study of the constraints affecting ornamental fish production in Sri Lanka

Although Sri Lanka is endowed with favourable climatic conditions and resources for breeding and rearing ornamental fish for export, a considerable number of ornamental fish producers as well as exporters have given up the industry within a relatively short period of time. This study was conducted to understand the present status of the industry and to identify the problems that have caused these failures. The study was conducted from March to December in the year 2007 and covered Colombo, Kaluthara, Polonnaruwa, Negombo, Wattala, Rathnapura, Avissawella, Kandy, Kegalle, Padukka, and Gampaha areas, where ornamental fish culture is known to be popular. The survey was carried out by interviewing ornamental fish farmers using a structured questionnaire survey that was designed to elicit the required information. Most (75%) of those surveyed were identified as small scale farmers. A majority (56%) of them used only cement tanks for their culture activities. Only 47% of farmers had proper technical knowledge or training on fish culture while 42% directly supplied their fish products to the expo1iers. The most important constraints identified by the study were as follows: (1) the sale price offish not changing in keeping with the increase in the material costs of production - Feed, cement, sand, transport and labour - in recent years. (2) Difficulty to find export markets for newcomers to enter the export market. (3) Lack of quality brooders and information on the most suitable fish varieties for the different climatic and water conditions in different areas in the country (3) Feed availability and cost. (4) Lack of adequate knowledge and technical support with regard to disease control and water quality management. (5) Difficulty to survive in the off season. (6) Difficulty in obtaining credit for expansion and the lack of sufficient involvement of responsible authorities in overcoming all these identified constraints.
