Inland pond

The study area was visited and surveyed twice in a month. During each visit waterfowl census was carried out and water samples were also collected to document changes in physico-chemical parameters and microbial analysis over the seasons. The aggregation of birds in the area is mainly related to the increase in migratory population of birds during winter. The variations inland bird aggregations as well as physico-chemical factors are discussed.

Present investigation deals with the fish faunal diversity in different habitat types in Hooghly district. Three types of floodplain water bodies were studied such as river, canal and ponds to determine the distribution of different fish species during different seasons. Results exhibit presence of 87 species in river Hooghly, 57 species in inland water and 47 species in different canals.

Lentic systems are a diverse set of inland freshwater habitats (Lakes and ponds) exist across the globe and provide essential resources and habitats for both terrestrial and aquatic organisms. The current work was intended to evaluate the quality of the selected ponds (Pond 1, 2 and 3) in and around Vellore district, TamilNadu. The water samples were collected to determine the physical and chemical parameters during every month in the year 2019. Water parameters such as temperature, pH, dissolved oxygen, Alkalinity, electrical conductivity, Chloride, Sulphate, Nitrate, Ca, Cl was studied.

Inland fishery resources are significantly contributed in fisheries sectors. In this regard, trend of inland fish production of Tamil Nadu was analyzed based on the available resources and utilization and seed production for the last decade. Calculated Average Annual Growth rate of fish seed production and inland fish production were 10.21% and 1.85%, respectively. The linear regression line for inland fish production was indicated that increasing trend for every year (R² = 0.673), while fish seed production was negative trend (R² = 0.094).

The Mekong Delta in the south of Vietnam is a highly dynamic landscape with rapid changes in land use. Costal forests of mangrove (Rhizophoraceae, Sonneratiaceae and Avicenniaceae) and the more inland Melaleuca forests are changed into shrimp ponds and rice fields.

small water bodies like ponds now contributes 80% of the country’s inland fish production. However, future growth in freshwater aquaculture to meet rising demand for fish is likely to be constrained by limited supplies of land for digging new ponds and of water to fill them. In this context, reservoirs offer immense scope for increasing fish production.
