Population dynamics of spotted scat, (Linnaeus 1766) from the Sundarbans of Bangladesh.

In Bangladesh, the mangrove areas of the Sundarbans are a hotspot for the spotted scat (), as the estuarine tributeries are significant zones for fishing, local marketing and foreign trading. Due to the widespread capture of spotted scats in the wild for a variety of uses, parameters of population were estimated using length-frequency and body weight data gathered from various sites in the southwestern forest areas of the country to comprehend the stock's status. Between May 2022 and April 2023, 1280  individuals were sampled from Khulna, Bagerhat and Satkhira.

Size dependent ingestion and effects of microplastics on survivability, hematology and intestinal histopathology of juvenile striped catfish (Pangasianodon hypophthalmus).

Microplastic pollution is drastically increasing in aquatic ecosystems and it is assumed that different sizes of microplastics have diverse impacts on the physiology of aquatic organisms. Therefore, this study was intended to examine the ingestion and size specific effects of polyamide microplastic (PA-MP) on different physiological aspects such as growth, feed utilization, survivability, blood parameters and intestinal histopathology of juvenile striped catfish (Pangasianodon hypophthalmus). In a 28-day exposure, the fish were fed with different sized PA-MP with a concentration of 500 mg per kg of feed in order to simulate highly microplastic contaminated environment.

Data describing effects of different phosphorus concentrations on growth and chymotrypsin inhibitors in NIVA Cya 43 using LC-MS.

Cyanobacteria's abundant production of bioactive compounds concerns unselective filter feeders in the aquatic food chain, but the factors driving this production remain poorly understood. Notably, nutrient availability, particularly concerning phosphorus and nitrogen, is believed to be a pivotal determinant of cyanobacterial mass development. In this data investigation, we aimed to explore the influence of dissolved phosphorus (PO) on the presence of chymotrypsin inhibitors, specifically Cyanopeptolin 954 (CP954) and Nostopeptin 920 (BN920), within NIVA Cya 43.
