Our article in the journal Aquaculture highlighted the first record of the isopod Tachaea spongillicola infesting wild fish species of aquaculture importance, particularly of carps. T. spongillicola was first recorded in freshwater sponges, 114 years ago and later recorded infesting freshwater prawns. Our recent study has further recorded infestation of this isopod in wild fish species. The expansion of host range from freshwater sponges to freshwater prawns and now to freshwater fish could pose a risk to aquatic industries in the years to come. We hypothesise that climate change could be a major factor contributing towards the expansion of the host range of parasites.
Fisheries is next to agriculture in offering employment opportunities for poor rural communities in Sundarbans. With around 17 million hectares of canals in India, there is considerable potential to generate jobs and improve the food security of rural populations if canals can be used for aquaculture production. This study explored the feasibility of aquaculture as a secondary use of canal infrastructure through use of net barrier partitions, installed and managed by local communities.
With the implementation of the new aquatic animal disease reporting in the Asia Pacific region from January 2021, and in lieu of the published QAAD Reports (last issue published was 4th quarter of 2020), NACA is publishing reported aquatic animal diseases submitted by countries in the Asia-Pacific region. This report covers the third quarter of 2021. The original and updated reports are available from the QAAD page.
