- CompanyFisheries and aquaculture:

+ Fishery production value in 2007: 1,259 billlion VND, increased by 1.4% compared with 2006 (70% from aquaculture, 30% from capture).

+ Fishing yield in 2007: 66,872 thousand tons, increased by 2.5%

+ Salangene nest production: 2.310 kg, increased 0,9%.

+ Aquaculture: Tiger shrimp, lobster, greenmussel, grouper, pearl oyster, seaweeds etc.

Tiger shrimp culture area in 2007: 4,328 ha, increased by 0.7%. Shrimp production: 5,476 tons, increased by 6.4%; shrimp seeds increased by 1.2%, reached 2,090 milion individuals, pearl production: 848 kg, decreased 46.3%.


Slide15 l.jpg

+ The lobster farming Company is developing strongest in Khanh Hoa, with 30,000 cages, of which 8.472 are in Nha Trang. However, lobster production in 2007 decreased by 51.4% to 595 tons, because of mass mortality by diseases since July 2007, lost 200 billion VND.

+ Khanh Hoa target up to year 2010: to incease fishing yield to 100-110 thousand tons, aquaculture output: 30-35 thousand tons, aquaculture area: 5000 - 5500 ha, and export turnover to 300 million USD.

- Investment–development focus:Nhatrang and its surroundings

5. Biodiversity changes/loss and exhaustion of marine resources:

Habitats degradation:coral coverage declined 31% in last 10 years; Seagrass bed decreased to 1/3 in area; Mangrove forest almost disappeared…

6. Nhatrang bay, may be due to eutrophication Impacts on the scenery, aesthetics, cutural and human resources

7. Changes on the coastal litho-dynamic processes, sedimentation, erosion....

8. Increase of natural disasters and diseases resulted by human activites

Coastline erosion Nhatrang bay, may be due to eutrophication

Landfill for coastal reclaim partly burying branching corals, releasing substantial amounts of sediments to coastal waters.

It also impacts on the scenic beauty
