Increased intake of animal-source foods (ASFs) is crucial to tackle multiple nutritional challenges in Bangladesh, and contribute to achieving targets under the Sustainable Development Goals (SDGs). Qualitative and quantitative data were collected to assess current ASFs intake behaviors and preferred ASFs, among three types of households, namely 1. aquaculture intervention (AI); 2. aquaculture non-intervention (ANI); and 3. non-aquaculture non-intervention (NANI) households and children aged 6–59 months, to understand whether intake of ASFs vary by the types of households. Purposive sampling was conducted to obtain a total of 100 households (AI, 50; ANI, 25; NANI, 25). Fish was the most commonly consumed (52.2–61.5%) and preferred (73.9–84.6%) ASF by the majority households, across study groups; although amount (mean ± SD) of intake (g/d/person) by NANI households was statistically significantly lower (NANI, 105.5 ± 53.3; p < 0.001), compared to other two groups (AI, 163.6 ± 64.7 and ANI, 159.6 ± 53). Fish species selection for household consumption was led by taste, health benefits, availability, and price. Pangasius was the first fish species of choice fed to children, due to having fewer small bones compared to other commonly consumed fish species. Dietary interventions to prioritize fish, in targeting increased intake of ASFs among study population, for improved food and nutrition security.

To evaluate the species diversity and strengthen the taxonomic identification of elasmobranchs in the Bay of Bengal, Bangladesh, a study was conducted in the southeast coastal region between January 2016 and March 2018. Using morphological and genetic identification techniques, this study presents 22 species from the region. Thirteen of these are new records. The new records consist of eight species from the family Dasyatidae, and one each from Mobulidae, Rhinobatidae, Narcinidae, Hemiscylliidae and Triakidae. Furthermore, four occurrences are first verified reports, and five are potential new records requiring further taxonomic investigation.

Three Tonkin numbfish, Narcine prodorsalis were caught off the coast of Bangladesh in April 2018. Amongst these three specimens, one was morphometrically measured, photographed and transported to be persevered and catalogued at the zoological museum in the University of Dhaka. The specimens were morphologically identified using taxonomic keys and DNA samples (fin clips) have been collected for further studies. These specimens represent the first record of Narcine prodorsalis in Bangladesh waters and extend its distribution range. This is the first western most confirmed record of this species from its previously designated range in the western Pacific and Eastern Indian ocean. This contemporary record includes Bay of Bengal within its current distribution range. Bangladesh J. Zool. 46(2): 147-154, 2018
