Abstract The possibilities of conservation and production potential of a large number of small indigenous fish of Bangladesh through aquaculture remains unexplored. Only a small number of carps has been used for polyculture throughout the country which provide employment for a large number of people in the domestic fish marketing chain as farmers, traders, intermediaries, day labourers and transporters. Special attention is needed for the culture and conservation of small indigenous species (SIS) because they are an important source of vitamin A and minerals. SIS used to be abundant in rivers, streams, beels (deeper portions in low-lying natural depressions), ponds, ditches and flood plains in the past, but have gradually been disappearing from natural systems, which in turn severely affects biodiversity.

Fish Marketing

Fishery sector plays a vital role in the socio-economic development of Bangladesh. In the fish economy of Bangladesh, one of the most flourishing traffic activities is fish marketing. This study was aimed to investigate the fish species availability, supply chain, quality loss, price behavior and constrains associated with fish marketing in order to provide better suggestion for efficient fish marketing in Jamalpur district of Bangladesh. Data were collected form Sadar upazila markets by using a structured interview schedule, focus group discussions (FGD) and key informant interviews (KII) with the stakeholders involved in supplying fish from farm to fork, such as- aratdars, retailers, and consumers during 2020-21. A total 78 fish species were found (72 Fresh water and 2 Marine water), among them 20 frequently, 17 less amount, 25 occasionally, and 16 species were rarely available in the market. It was estimated that 72% fish species were sourced from culture fishery whereas 28% were from capture fishery. About 91.5% fishes in Jamalpur markets were supplied locally, whereas rests were from other districts. The post-harvest quality losses of fish in the sampled markets were assessed which indicate that small indigenous species (SIS) spoiled quicker than medium to large sizes fishes due to different factors. The price behavior of the fish market influenced by the demand of the fish species, quality, size, catching sources (culture fishery or capture fishery) and the purchasing time (beginning, middle or last time of market). The study found positive correlation between the market price and fish quality. Several problems of fish market were identified resulting consumer dissatisfaction and financial losses for fish traders. Considering the importance of fish market to the economy, this study suggested to take necessary steps for establishing modern fish market to ensure the adequate quality maintenance of fish with efficient marketing.

A research work was conducted to observe the beel management of the Dhaka beel situated in Tangail district, Bangladesh. Data were collected through questionnaire survey, discussion and interviewing. Dhaka beel is a 13ha semi-enclosed beel brought under the nursery management project in 2010. The beel was stocked with approximately 100000 fish larvae of 4 days old during May to June. After 60 days of proper management the stocked larvae were sampled and 70,000 of fry were obtained. In the studied beel the annual production was 2.4 mt in 2009 where beel nursery management has increased the production to 7.10 mt in 2010 which also included several non-stocked indigenous fish species. Socio-economic conditions of people were also improved where 80% of the people believed that it was true. Beel management has played an important role to minimize the rapid reduction of many important indigenous species through four to five months of management where fishes got the chance of recruitment. Management, guarding, harvesting, and income were equally shared among the group members. Findings of the present study suggest that beel nursery management can be an excellent scope for improvement of fish production and socio-economic status of the adjacent people.

Background Fish and fisheries are important for the livelihoods, food, and income of the rural population in Bangladesh. Increased rice production and changing agricultural patterns have resulted in a large decline in inland fisheries. Implementation of carp pond polyculture has been very successful, whereas little focus has been given to the commonly consumed small indigenous fish species, some of which are rich in vitamin A and minerals, such as calcium, iron, and zinc, and are an integral part of the rural diet. Objective The overall objective of the research and capacity-building activities described in this paper is to increase the production, accessibility, and intake of nutrient-dense small indigenous fish species, in particular mola ( Amblypharyngodon mola), in order to combat micronutrient deficiencies. The large contribution from small indigenous fish species to recommended intakes of vitamin A and calcium and the perception that mola is good for or protects the eyes have been well documented. Methods An integrated approach was conducted jointly by Bangladeshi and Danish institutions, linking human nutrition and fisheries. Activities included food-consumption surveys, laboratory analyses of commonly consumed fish species, production trials of carp–mola pond polyculture, teaching, training, and dissemination of the results. Results No decline in carp production and thus in income was found with the inclusion of mola, and increased intake of mola has the potential to combat micronutrient deficiencies. Teaching and training of graduates and field staff have led to increased awareness of the role of small indigenous fish species for good nutrition and resulted in the promotion of carp–mola pond polyculture and research in small indigenous fish species. The decline in accessibility, increase in price, and decrease in intake of small indigenous fish species by the rural poor, as well as the increased intake of silver carp ( Hypophthalmichthys molitrix), the most commonly cultured fish species, which is poor in micronutrients and not preferred for consumption, are being addressed, and some measures taken by inland fisheries management have been discussed. Conclusions The successful linking of human nutrition and fisheries to address micronutrient deficiencies has relevance for other countries with rich fisheries resources, such as Cambodia and countries in the Lake Victoria region of Africa.

Vitamin A (retinol) is one of the key elements for regulating the immune response and controls the division and differentiation of epithelial cells of the mucous membranes of the bronchopulmonary system, gastrointestinal tract, urinary tract, eyes, etc. Its significance in the context of the COVID‑19 pandemic is difficult to overestimate. However, a number of studies conducted in the past have associated the additional intake of vitamin A with an increased risk of developing cancer, as a result of which vitamin A was practically excluded from therapeutic practice in developed countries. Our review highlights the role of vitamin A in maintaining human health and the latest data on its effect on the development mechanisms of somatic pathology.

Abstract The article is a retrospective analysis of the development of airborne laser scanning technology in the country in the past twenty years, i.e. from the beginnings of this technique use in Poland to the present day. The emphasis in the text is placed on development trends and scientific and application problems in the field of technology undertaken by national research centres. The review is based on numerous publications in this field, which have been released over two decades mainly in the “Archive of Photogrammetry, Cartography and Remote Sensing”. Therefore, the article is a presentation of the progress in the area of airborne laser scanning through an attempt to systematize and review national publications in this scope. It also presents the development of the national production potential and the level of the country’s coverage with data and products derived from airborne laser scanning.
