marine ornamental fish, they done it with every kind of way by using special nets even by damaging coral reefs using anesthetic potassium cyanide.
2.7. Coral Reef Economical Value
On recent coral reefs threats, a pressing issue that needs to be done is to value its economic valuation of coral reefs function both as supplier of goods or
services. Economical assessment could be described or derived from fishery value or value as a protective beach that has market value. Where the value can be
derived based on the demand, supply, price and cost Spurgeon 1992 Barton 1994 explains that the economic value of coral reef ecosystems is
the value of all instruments available to them including a source of food and ecological services. The value of all the instruments found on coral reef
ecosystems can be quantified by the total economic valuation methods Total Economic Valuation TEV. Based on neoclassical economic theory such as
consumer surplus and willingness to pay can be approximated value of coral reef ecosystems with sense of no market value non-market value.
According to Fauzi 2004 Economic valuation can be defined as an attempt to provide a quantitative value to goods and services produced by natural
resources and the environment both on market value or non-market value. Economic assessment was a economic tool using a specific valuation technique to
estimate the monetary value of goods and services provided by a natural resource. Economic valuation purpose, among others, used to demonstrate the linkages
between natural resource conservation and economic development, then economic valuation could be an important tools in increasing public awareness and
appreciation of the environment itself. Described by Fauzi 2004 that there were three characteristics owned by its
resources that is 1. Non-renewable resources, can not be renewed when they are extinct. If as an
asset can not be preserved, then they trend to extinct. 2. Eexistence of uncertainties, such as coral reefs damaged or missing. There
should be a potential costs must be purchased if these natural resources tend to extinct.
