Fishermen in Van Don District in the northern province of Quang Ninh are enjoying a new prosperity thanks to a VND5.5 billion provincial programme that began in 2001 to develop caged fish breeding.

 

The size of fish and shellfish breding in cages in the province’s coastal districts has increased from 180 to 3,700 cages. Sixty per cent of households now engage in caged fish breeding, according to the district’s economic office.

 

Situated in an area of Bai Tu Long Bay, Van Don District covers more than 7,000ha of salt-marsh tidal flats and 160,000ha of water surface. Nearly 2,000ha have been dedicated to aquaculture. The district expects to generate 2,000 tonnes of seafood in 2006, earning a turnover of VND20-25 billion.

 

The district has more than 600 islands, both large and small, and water channels among them of depths ranging from 7-15m, ideal conditions for aqua-farming.

 

Research shows that the high density of various marine algae in these waters provides particularly favourable conditions for breeding shellfish.

 

The district’s aquaculture industry has developed vigorously. Fifty households in Ngoc Vung Commune alone produced 150 tonnes of seafood in a 90ha farming area in 2005.

 

Success stories

 

Local fisherman Nguyen Van Quy is an example of how perseverance in caged fish breeding has paid off in the form of prosperity anda better quality of life.

 

Quy once plied the waters offshore for his livelihood. But, in 1989, he sold his fishing boat and invested his money in raising grouper in cages on Nhu Island. This intial experience, however, ended in Quy going bankrupt.

 

"Even when I was a kid, I had seen with my own eyes how grouper can survive in shallow water when others kinds of fish can’t," he recalled. Once again he tried to raise fish in shallow pools, but the fish could not survive seasonal weather and temperature changes.

 

He finally discovered that grouper could survive quite well in deeper water, so he dredged deeper pools in the lagoon to hold fish when the temperatures changed suddenly.

 

After a decade of experimenting, his first batch of fish survived through both the winter and summer. He spent time reading and studying the growth stages and reproduction period of the song fish, and adjusted the density of fish raised in a certain area of the lagoon.

 

With the first successful batch, he reaped a profit of hundreds of millions of dong and planned for further expansion. He borrowed additional money from relatives to add an additional three hectares of breeding pools at Sa Kep lagoon in Ha Long Commune.

 

He now has a farm worth about VND10 billion and has generated stable jobs for 24 workers. In 2005, he harvested 20 tonnes of fish generating revenues of VND2.6 billion.

 

Another veteran fisherman, Kieu Anh Chinh from Na San Village in Ban Sen Commune, was the first in his area to successfully raise tu hai (a variety of mussel).

 

Chinh also began raising oc nhay (snails) in 2000 and enlarged his farm from an initial five hectares of tidal flats. He raises 30,000 tu hai yearly, with 100 cages and 4,000 fingerlings contributing to large revenues of more than VND30 billion each year.

 

"Raising tu hai itself is not difficult. The obstacle is that our fishermen can’t afford facilities and fingerlings," said Chinh.

 

All aboard

 

Six years ago, most of the 200 plus households in the island commune of Ban Sen engaged in offshore fishing and barely made ends meet. They are now successfully piloting the model of aqua-farming.

 

Currently, 34 households raise different kinds of marine life, predominantly tu hai, along with a variety of shellfish spanning a 100ha area.

 

Aquaculture in Ban Sen had boarded the train for economic development, said Pham Hai Dang, secretary of the commune’s Party Committee
