Sarawak is well known with its Terubok which is scientifically known as Tropical shad Tenualosa. In Sarawak, there are two types of Tenualosa that found namely Tenualosa toli and Tenualosa macura. However, due to the overexploitation and heavy fishing of terubok, the total catch landing has been declining. Therefore, the main objective of this study is to investigate the potential of establishing sustainable terubok fisheries in order to sustain the population of terubok and livelihoods of Sarawak fisherman. This study is conducted in the core terubok area which are Batang Lupar, Batang Lassa and Batang Sadong. This study employed Contingent Valuation Method (CVM) to estimate the willingness to accept (WTA) of the fisherman to conserve terubok. This study found out that the bidding amount, race which is Malay and Melanau, size of household and the fisherman experience may affect the WTA of the fishers. Besides, RM 301.08 is the average amount of compensation that will be given to the Terubok fisherman in order to conserve the Terubok populations. This study also recommends that the Terubok fisherman should be more educated andeducational training for the fisherman should be provided so that they may realize the importance of conserving Terubok.

Over the year, the population of local terubok (Tenualosa toli) is being threatened due to overexploitation. Terubok is one of the famous and important commercially fish in Malaysia which only found in Sarawak rivers. Nowadays, the landing of local terubok are very limited and difficult to obtain since 1980s. Environmental goods like terubok has a value to society, however, it is difficult to obtain and express these economic values in monetary terms. One of the methods that commonly used to evaluate non-market valuation which is Contingent valuation method (CVM) was used in this study to estimate the willingness-to-pay (WTP) of local communities to conserve terubok. A dichotomous choice contingent valuation method (DC-CVM) in single bound formulation was employed in this study. The general objective of this study is to examine the monetary value that local people are willing to pay to conserve terubok in Sarawak. The result shows that WTP of Yes decreases as the price of the offer increases. Result indicates that respondents are willing to pay at an average of RM31 per annum for sustainability of Terubok.

Wetland are among the most productive of the world’s ecosystem and the most threatened tropical ecosystem. Mangrove forest is very useful and gives various benefits and it is extremely productive ecosystem that provide numerous good and services both to the marine environment and people. This research was conducted to identify the factors that influence the perception of local communities towards wetland biodiversity conservation which brings more beneficial towards our daily life. The interest group for this study is focuses on communities who live near the mangroves forest area and the location of study is in Telaga Air, Sarawak. The method that been used in this study was Factor Analysis and multiple regression. There are 15 factors that have been extracted by using Factor Analysis. Out of the factors, only 7 factors that are chosen as independent variables to run the regression analysis with the dependent variable of respondent’s Perception. Lastly, the study found that the factors of community awareness, garbage disposal and level of pollution have a strong relationship with the perception of residents towards wetland biodiversity conservation in Telaga Air. Overall, this study shows that majority of local communities that live nearby mangroves shows a positive attitude towards the conservation of wetland in Kuching. All the activities that being carried out in mangrove area should be monitor by authorities in order to ensure the sustainable of the mangrove forest are protected and guaranteed.
