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.

The author has carried out a retrospective analysis of environmental data about the Azov limans of the Krasnodar Krai. The increasing liman deterioration leading to their complete disappearance has been noted. Assessment of the priority of liman fish economy has been given. In terms of biological melioration there have been offered measures on stocking limans with herbivorous fish species of different age: grass carp Ctenopharyngodon idella and white silver carp Hypophthalmichthys molitrix , and determined necessary amounts of yearly stocking of the Azov limans. Modern data on the overgrowth in the water area of the Azov limans by higher aquatic vegetation have been presented in the context of the main groups of limans. The groups of limans were graded according to the priority of conducting biological melioration measures in them and practical recommendations were given on the quantity and places of stocking of the Azov limans grass carp and white silver carp depending on the degree of overgrowth. The necessity of using the funds received as compensation for the harm to water biological resources in the Krasnodar Krai for the artificial reproduction of grass carp and white silver carp and their introduction into the Azov limans has been substantiated. The article shows that stocking limans with herberous fish species will both ensure ameliorative effect and increase amount of fish commercial output.

AbstractThe aim of this study was the investigation of water, sediments and fish tissues contamination with heavy metals. All samples were taken from the Danube River in Belgrade region, a location upstream from Batajnica. Concentrations of Cd, Hg and Pb in water samples were not detected, while concentrations of Zn, Fe, Cu and As were in the range of 0.004 - 0.330 mg L-1. Iron was the most deposited metal in sediment samples in contrast to water samples where all investigated metals were detected. For the purpose of heavy metals determination in fresh fish tissue, fifteen samples of three different fish species, silver carp (Hypophthalmichthys molitrix), common carp (Cyprinus carpio) and wels catfish (Silurus glanis) were collected. Concentrations of Pb, Cd, As and Hg were determined in the digestive tract, liver and muscle by absorption spectroscopy. The highest concentration of Pb was in the digestive tract in all three fish species, ranging from 0.036 to 1.518 μg g-1, while Cd was mostly deposited in the liver. Concentrations of As were in the range of 0.36 - 0.73 μg g-1in Hypophthalmichthys molitrix, 0.013 - 0.18 μg g-1in Cyprinus carpio and 0.003 - 0.005 μg g-1in Silurus glanis tissues, while the content of Hg was equal in all tested tissues of carp. Concentrations of all metals were found to be present in the fish samples at different levels, but these values are under the maximum residual levels prescribed by the European Union (EU) and the maximum allowed concentrations (MAC) for Serbia, so the fish meat is acceptable for the human consumption.

A study was conducted to observe the captive breeding performance with maturing sages and fry nursing of the threatened indigenous fish species Notopterus chitala at Arabpur fish farm  (Longitude 89°12'15" E, Latitude 23°10'30" N), Jessore, Bangladesh during 1998 to 2001. The peak period of ovulation for N. chitala was found from July to August and the fish attained its first maturity at third year of age. Captive breeding is the most effective and basis process in case of N. chitala when cemented tank was used for collection of fertilized eggs, percentage of fertilization and hatching in stead of bamboo pole, plastic barrel, cemented tank and barrel made of tin. In the nursery practices live benthos, hatching of Thai punti and silver carp were used as feed of the spawn but the highest growth and survivability of the fish fry obtained by using Barbodes gonionotus (thai punti) spawn and live Tubifex sp. (benthos).Key Words: Fertilization; hatching; growth; survivabilitydoi: 10.3126/eco.v13i0.1628Ecoprint (An International Journal of Ecology) Vol. 13, No. 1, 2006 Page : 41-47

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.

Literature reviews of all references concerning the parasitic fauna of fishes in fish farms of Babylon province, middle of Iraq, showed that a total of 92 valid parasite species are so far known from the common carp (Cyprinus carpio), the grass carp (Ctenopharyngodon idella), and the silver carp (Hypophthalmichthys molitrix) as well as from three freshwater fish species (Carassius auratus,Liza abu, andHeteropneustes fossilis) which were found in some fish farms of the same province. The parasitic fauna included one mastigophoran, three apicomplexans, 13 ciliophorans, five myxozoans, five trematodes, 45 monogeneans, five cestodes, three nematodes, two acanthocephalans, nine arthropods, and one mollusc. The common carp was found to harbour 81 species of parasites, the grass carp 30 species, the silver carp 28 species,L. abu13 species,C. auratusone species, andH. fossilisone species. A host-parasite list for each fish species was also provided.

An experiment was conducted to assess the relative performances of indigenous and exotic fish species under commercial culture system at Muktagacha and Trishal upazila in Mymensingh district. Six exotic fish species namely Thai koi (Anabas testudineus), Thai pangus (Pangusius hypophthalmus), Silver carp (Hypophthalmichthys molitrix), Vietnam koi (Anabas testudineus), Big head carp (Aristichthys nobilis) and Tilapia (Oreochromis niloticus) and nine indigenous fish species namely Rui (Labeo rohita), Shing (Heteropneustes fossilis), Sar punti (Puntius sarana), Gulsha (Mystus bleekeri), Koi (Anabas testudineus), Mrigal (Cirrhinus cirrhosus), Kalibaush (Labeo calbasu), Catla (Catla catla) and Magur (Clarias batrachus) were selected in Muktagacha while exotic Big head carp and indigenous Gulsha, Koi and Magur were lacking for observation in Trishal upazila. Results revealed that the production of exotic Thai pangus was comparatively higher in Muktagacha (5810.81 kg/acre) than Trishal (4521.74 kg/acre) upazila. In contrast, silver carp and tilapia production were 3063.04 kg/acre and 1008.26 kg/acre in Trishal, respectively which were higher than Muktagacha. Average selling price of tilapia, Vietnam koi and silver carp was also comparatively higher in Muktagacha than Trishal upazila. Similar observation was also obtained in respect of indigenous fish species. On the other hand, average selling price of shing was found highest (BDT. 333.33 per kg) in Muktagacha than Trishal while other fish species were sold at similar price. Gross income was also significantly higher with the exotic fishes in Muktagacha accounted for BDT. 858,716/acre/cycle while the highest gross income obtained with the indigenous fishes was in Trishal upazila, valued BDT. 121,5987/acre/cycle. It can be concluded that, both indigenous and exotic fish farming has spread in the area because of easy to adopt culture system, availability of fry, feed, good profit and high demand in the market. Some limitations of the ongoing practices have been identified that need to be addressed properly by the concerned authority. Progressive Agriculture 29 (4): 371-379, 2018
