Abstract:An investigation was carried out on fish landing centers, fish markets and fish fauna of the Mymensingh town to overview the location of the fish landing/entering centers, the source of supply and availability of fisheries organisms in Mymensingh town. The investigation was conducted from October 2009 to September 2010 in sixteen landing centers and markets of Mymensingh town. Among a total of 122 species of fishes were available of which, 113 were finfish and 9 were shellfish. Out of 113 finfish, 85 w… Show more
“…Hilsha and Bagda chingri were leading position from marine and brakish water species. These findings are much convenient with Chandra et al [25] where they observed 99 freshwater fish species and 14 marine fish species in the 16 fish markets and five important fish landing centers of Mymensingh districts.…”
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.

“…The helminthic parasites were identified morphologically and parasitologically using standard identification keys and pictorial guides [14][15][16][17][18].…”
An investigation was conducted from November, 2010 and August, 2011 in Lake Lugo (Hayke), northeast Ethiopia, with the aim of determining the prevalence and identifying the species of internal parasites from freshwater fish. A total of 412 randomly selected fishes comprising of 225 Oreochromis niloticus, 72 Clarias gariepinus and 115 Cyprinus carpio were examined for internal helminthes parasites. An overall prevalence of 47.8% (197/412) internal parasitic infestation was assessed. Statistically significant difference at p<0.05 was noted in the prevalence of internal parasites among the different species, length and weight of fish. However, the difference between sexes was not statistically significant at p>0.05, but the prevalence was a bit higher in females (48.31%) than males (47.44%). Prevalence of internal parasites was higher in Clarias gariepinus (91.7%) followed by Oreochromis niloticus (50.22%), and Cyprinus carpio (15.6%) species. Six parasite species: three nematodes (Contracecum spp., Camallanus spp., Eustrongylides spp.); one trematode (Clinostomum spp.) and two cestodes (Ligula intestinalis, Proteocephalus spp.) were identified from the body cavities and gastrointestinal tracts of fishes. In conclusion, the prevalence of internal parasitic infestations was very high and the study determined six parasitic species present in fish, which were not previously examined in this Lake.
“…The parasites were again washed with 70% alcohol, temporarily mounted in Canada balsam on slides, and finally examined under a compound microscope (BX51, Olympus, Japan) and identified according to Chandra (2004). The prevalence, abundance, and mean density of parasites were estimated according to Margolis et al (1982).…”
Silver carp, Hypopthalmichthys molitrix is one of the most economically valuable fish species in Bangladesh. However, its production is often hindered by parasite-induced mortality. The present study reports the intensity of parasitic infestation in 216 specimens of H. molitrix collected from different fish markets in Rajshahi City, Bangladesh. Nine different parasite species (Trichodina pediculatus, Dactylogyrus vastator, Ichthyophthirius multifilis, Gyrodactylus elegans, Lernaea sp., Apiosoma sp., Myxobolus rohitae, Camallanus ophiocephali, and Pallisentis ophiocephali) were recovered from the gill, skin, stomach, and intestine of host fish. The highest level of infection was observed for host skin, while lower levels were observed for host gill, stomach, and intestine. The results also revealed that the intensity of parasite infection in different organs of H. molitrix varied with the season. In particular, the highest levels of infection were recorded during the winter period (November-February), when fish are most susceptible to parasites. The findings of the study will help in the management and conservation of H. molitrix.
