Aquaculture in brackish water proves more rewarding than in freshwater

Small-scale fish farmers in Malaysia earn 2.5 times more farming aquaculture in brackish-water, compared to freshwater, according to a study published in the Pertanika Journal of Social Sciences & Humanities.
The study, led by Roslina Kamaruddin, a researcher from University Utara Malaysia, was intended to understand why some fish farmers are more successful than others.

As part of the analysis, Kamaruddin queried 216 small-scale freshwater and brackish-water pond fish farmers from the state of Kedah about their assets, such as education and investment capital, fishing strategies, and household income.
It was found, overall, higher education level and experience, as well as higher investment and operating costs positively correlated with higher levels of best management practices and household income.

The highest incomes were among brackish-water fish farmers - in part because brackish-water species generate higher profits, but also because brackish-water farmers are more likely to use best management practices than freshwater farmers.
Brackish-water species require intensive care, so farmers use best management practices such as pond preparation and fish health management to help ensure high survival rate and best quality produce.
"Good management is crucial for sustainable aquaculture and this study showed that fish farmers need more training and financial support to implement
best practises," Kamaruddin said.
While brackish-water species generate more profit, they also require high investment, operating costs and technical knowledge. More brackish-water farmers are financed by banks and agencies, whereas freshwater farmers are more likely to use personal financial resources. Freshwater fish farmers often supplement their income with other sources, such as agriculture.
Not all aspects are better for brackish-water farmers, however. The study shows they experience higher levels of stress, worry and anxiety when their underwater farms were adversely affected. In addition, brackish-water farms had a higher impact on the environment as they used more fertilisers and antibiotics.
The study highlights that measures to boost education, training, and financial investment should be prioritized to improve fish farmers' livelihood, the study notes. For example, credit institutions could provide credits or loans which cater to small-scale farmers. Training for best aquaculture practises should also be readily available.
Other policies could include differentiating between aquaculture products from farms with good management versus poor management, or penalizing farmers who do not follow best practises.
