The main objectives of the study were to determine the present status of fish biodiversity and socio-economic condition of fishermen in Belai beel during February 2016 to September 2016 by survey method using questionnaires, field visit and interviewing with the fishermen. The results indicated that about 27 species of fish fauna were found in the Belai beel, among them 23 species were indigenous and 4 species were exotic. Major dominant species were Rui (Labeo rohita), Catla (Catla catla), Bata (Labeo bata), Shingi (Heteropeneustes fossilis), Magur (Clarius batrachus), Tengra (Mystus tengra), Chanda (Chanda nama), Kakila (Xenentodon cancila), Common carp (Cyprinus carpio), Mola (Amblypharyngodon mola) in the study area. During the study period two critically endangered (Puntius sarana, Pangasius pangasius), two endangered (Labeo bata, Channa marulius), and three vulnerable (Chanda nama, Channa orientalis, Notopterus notopterus) fish species were found in the Belai beel. Analysis of socio-economic condition of fishermen showed that maximum (70%) had nuclear family and others (30%) had joint family, as well as fishermen, belonged to the age groups of 31 to 40 years (50%) and the others were 15 to 30 (20%), 41 to 50 (18%), 51 to 60 (10%), 61 to70 (2%). Overall, the present study suggested that fishermen communities should be educated by creating awareness for the proper conservation, management, and enhancement of biodiversity in the Belaibeel.Asian J.

Fresh water wetlands are fragile ecosystems, which are fast deterioring and shrinking due to manmade activities. The fish composition of Huchharayanakere of Shikaripura was studied for a period of twelve months from January to December 2015. The icthyo-faunal diversity of this pond confirmed the occurrence of 13 species of fishes belonging to 5 families. The family Cyprinidae represented by 9 species. Families Anabantidae, Bagridae, Clupeidae and Notopteridae were represented by only a single species. Simultaneously the physico-chemical condition of the water body revealed that water quality is suitable for fish culture. The study of fish fauna of an aquatic body is useful for planning of fisheries development. The pond needs proper management and utilization of this fish wealth and sustainable steps to monitor and conserve the fish health. The present study revealed that Huchharayanakere of Shikaripura harbors wide varieties of fish with economic importance in local and global trade. The study will provide future strategies for development and fish conservation.

The diversity of freshwater fishes which inhabit in the river of Daerah Istimewa Yogyakarta is not yet well documented. Complete documentation is needed as starting point and continuous research on the fish diversity in DIY. Boyong-Code River flows across the DIY, and it upstream is located on the hillside of Merapi volcano. The Code River upstream is called Boyong River. The research was aimed to acquire data about the diversity of fish fauna along the Boyong-Code River in the DIY. Further, the research purpose is to know which species are rare, potential for aquaculture, and introductive. Samples are taken along the Boyong-Code River starting from upstream to downstream. Samples were collected using Purposive Random Sampling methods with fishnets. Sampling area generally divided into three location i.e., upstream, middle-stream and downstream. Species diversity of fish in the Boyong-Code River is consisted of 24 species, with 5 introductive species. There are eleven native fish species which are potential for cultivation (aquaculture), i.e.: Barbodes binotatus, Mystacoleucus obtusirostris, Rasbora lateristriata, Rasbora argyrotaenia, Barbonymus balleroides, Osteochilus vittatus, Hampala macrolepidota, Anabas testudineus, Channa striata, Clarias leiacanthus and Clarias batrachus. The Boyong-Code River is a decent habitat for fishes. Many introduced fishes starting to invade the Boyong-Code River intentionally or unintentionally by human

The black bass, Micropterus salmoides, was introduced to Brazil from North America in 1922. Since then the species has been reared in aquaculture facilities intended to stock reservoirs as additions to native stocks available for angling. At present no scientific information on the biology of black bass in Brazilian waters is available. Since black bass dispersion may cause severe impacts on native Brazilian fish fauna, information on the basic biological parameters of this species is necessary. The objective of the present study is to provide information on the growth, age structure, and mortality of the species in a small reservoir in southern Brazil, where the species reproduces regularly. Based on scale readings, the von Bertalanffy growth curve was calculated and compared to the length-frequency distribution of the population. Both methods showed similar results. Maximum length was about 44 cm. The mean length at the end of the first year was 23.1 cm (s.d. = 13.88); at that of the second, 37.3 cm (s.d. = 12.52); and 41.4 cm (s.d. = 9.92) at the third. Oldest fish were three years old. The growth performance index ø' was 3.28 cm year-1. Mortality increased from 0.16 year-1 between the first and the second cohort, to 0.8 year-1 between the second and third. The results show that black bass in Brazil grows faster than in its area of origin, but longevity is shorter and body shape, stouter. The cause of high mortality at a relatively early age may be connected with the loss of genetic diversity due to inbreeding of the Brazilian stocks, which originated from few introduced individuals a long time ago. The fact that black bass reproduces in reservoirs and grows rapidly may be considered a threat to conserving fish diversity in Brazilian ecosystems.

Reservoirs have been built in almost all of the hydrographic basins of Brazil. Their purposes include water supply for cities, irrigation and mainly, generation of electricity. There are more than 700 large dams and associated reservoirs in the large rivers of the country. These reservoirs favor local and regional economic development, but they also bring serious and irreversible alterations in the natural hydrologic regime of rivers, affecting habitat quality and the dynamics of the biota. In the impounded area, the main impact is the change from lotic to lentic water, which influences aquatic fauna, including fishes. Impacts of reservoirs present relevant spatiotemporal variations. Immediately after reservoir formation, fish species richness usually increases due to incorporation of surrounding habitats, but richness decreases as reservoirs age. However, impacts downstream of dams appear to be similar or stronger than those that occur within the reservoir. Dams promote discharge control, altering the seasonal cycles of floods. These effects are augmented when dams are constructed in cascades. Therefore, dams profoundly influence composition and structure of fish assemblages. Most affected species are the rheophilics and long distance migratory that require distinct habitats to fulfill their life cycles. Populations of migratory species may collapse or even disappear in intensely regulated stretches. Management actions taken to minimize impacts of dams in Brazil historically considered construction of fish passages, fishery control and stocking. The results of these actions are questionable and/or with clear failures. In this paper, we give emphasis to the Paraná River basin, the most affected by dams in Brazil. We describe some patterns in the alteration and decline in fish diversity in areas influenced by dams. We also discuss negative consequences in the fishery and ecosystems functioning. Finally, we argue the relevance and the success of the management actions taken and present some suggestions to improve conservation of the ichthyofauna in South American basins influenced by dams.

AbstractThe late Permian is a transformative time, which ended in one of the most significant extinction events in Earth’s history. Fish assemblages are a major component of marine foods webs. The macroevolution and biogeographic patterns of late Permian fish are currently insufficiently known. In this contribution, the late Permian fish fauna from Kūmas quarry (southern Latvia) is described for the first time. As a result, the studied late Permian Latvian assemblage consisted of isolated chondrichthyan teeth of Helodus sp., ?Acrodus sp., ?Omanoselache sp. and euselachian type dermal denticles as well as many osteichthyan scales of the Haplolepidae and Elonichthydae; numerous teeth of Palaeoniscus, rare teeth findings of ?Platysomus sp. and many indeterminate microremains. This ichthyofaunal assemblage is very similar to the contemporaneous Lopingian complex of the carbonate formation from the Karpėnai quarry (northern Lithuania), despite the fact that Kūmas samples include higher diversity and abundance in fossil remains. The differences in abundance of microremains could possibly be explained by a fresh water influx in the northeastern Zechstein Basin margin, which probably reduced the salinity of the sea water. The new data enable a better understanding of the poorly known late Permian fish diversity from the Lithuania-Latvia Region.

The study was conducted to determine the fish retailer’s livelihood and socio-economic status in three markets of Jashore for a period of six months from February to August, 2016. The average net profit of fish retailers was found higher in Boro bazaar (Tk.350) followed by Palbari bazaar (Tk.325), Chuadanga Bus Stand bazaar (TK.275). The average age groups of 20-65 years were found among the markets. The study shows that 53% fish retailers had nuclear family and 47% had joint family. Most of the housing conditions were kacha (69%) and Muslim fish retailers were predominant in all markets. Among the total 45 traders interviewed, 42% were illiterate, 31% have primary level education, 24% have secondary level education and none of them had bachelor level of education. It was found that fish retailers of Boro bazaar and Palbari bazaar sold an average of 35 kg fish daily, compared with Chuadanga Bus Stand bazaar 15 kg per day. The daily supply of fish in Boro bazaar can be estimated at 1.6 MT (25 retailers’ × 65 kg) while 0.3 MT (15 retailers × 20 kg) and 0.45 MT (15 retailers × 30 kg) in C.B Bazar and Palbari bazaar respectively. Improvement in basic infrastructure such as, clean water supply, sanitation facilities, adequate drainage and ice facilities are recommended by the present study. Asian Australas. J. Food Saf.

Abstract. Haryono, Wahyudewantoro G. 2020. The alien freshwater fish of Mount Galunggung, West Java, Indonesia. Biodiversitas 21: 1401-1408. Mt. Galunggung, located in West Java, Indonesia, is an active volcano renowned for its deadly eruption in 1982. This area has many waters bodies, but the fish communities have not been recorded, especially the alien or introduced fish species. Hence, the objective of the present study was to determine the alien fish diversity, abundance, local distribution and utilization in Galunggung vicinity. The study was done in March 2013 using survey method covering 10 stations. Fish sampling was based on catch per unit of effort (CPUE) using mainly electrofishing, gillnet and cast net. A total of 24 species were recorded during the survey, in which 13 were listed as introduced species. Poecilia reticulata was the dominant species with 7.4 ind./St and followed by Xiphophorus helleri with 5.3 ind./St. Both species were also widely distributed on the sites with 70% local distribution. The alien species in this area are mostly used for ornamental fish.
