“…This data was matched with previous study of water temperature (24-31 °C) on H. molitrix that was reported for maximum growth by Mahboob and Sheri (1997). Results from the clinical observations of fishes (in all three fish farms) suggested that H. molitrix was appeared comparatively bright, healthy and normal during April to June.…”

Investigation on changing pattern of health status of juvenile Hypophthalmichthys molitrix from farming systems in Bangladesh

An experiment was carried out to investigate the health status of Hypophthalmichthys molitrix among three different fish farms at Mymensingh district of Bangladesh. Fish sampling and water quality parameters were collected on a monthly basis. Samples of skin, muscle, gills, liver and kidney were examined through histological technique. Results from water quality parameters suggested that water temperature had a distinct effect on fish health of H. molitrix, which was mostly evident during the colder months. Infectious symptoms were usually evident in July to October and the severity of pathology was increased in November and December. These were evident from their clinical signs that include scale loss, haemorrhagic lesion, and reddish spots or from their histopathological symptoms such as necrosis, pyknosis, inflammation, haemorrhage, hypertrophy, missing of gill lamellae, vacuums, tubular and pillar cells degeneration, inflammation, clubbing, and suspected bacterial colonies. Results suggest that the health condition of the fishes from BAU fish farm was the best over the other two farms, whereas Government fish farm followed by NGO fish farm were severely affected with EUS, protozoan and bacterial infection. Moreover, internal organs like liver and kidney were more affected than skin, muscle and gills.

“…For larval culture, these traditional practices still depend to a large extent on live food organisms that grow naturally in culture ponds. The role of zooplankton in the survival of larval carps in these nursery ponds has been documented convincingly (Alikunhi et al, 1955;Mitra and Mohapatra, 1956;Jhingran and Pullin 1985;Yadava and Garg, 1992;Garg and Bhatnagar, 1996;Mahboob and Sheri, 1997;Sharma and Chakrabarti, 1999;Gupta and Noble, 2001;Jha and Barat, 2005a;Jha et al, 2006).…”

Fish and Fisheries in Indian Heritage and Development of Pisciculture in India

From the beginning of history, fish became an inseparable part of human life in India. Over the course of time, fish proved to be food of high nutritional value through empirical observation. The practice of casting a fish motif on coins or stone sculptures and seals, or using fish insignia in flags by ancient Hindu and Muslim rulers in medieval India, or the use of fish as a symbol of fortune and an object in literature and folksongs, prove that fish transcended the narrow limits of cultural segmentation. The establishment of cities with an ever-increasing population and changing food habits created an obvious demand for large-scale fish culture in the 20th century. Fish production from natural waterbodies trended downward during the later decades of the 20th century. Meanwhile, the technologies of induced breeding and polyculture virtually revolutionized the freshwater pisciculture sector over the last 50 years, and Indian fish production registered excellent growth-from 0.75 mt in 1950 to 6.3 mt in 2002. Hopefully, pisciculture may be part of the solution to the increasing need for food diversity and arresting the decline in per capita protein nutrition of the Indian populace in the years to come.

“…The mean GSI was significantly larger in the highest PNA treatment (3446 µg/g PNA) when compared to that of controls which suggests that PNA exposure can increase gonadal mass. Mahboob and Sheri (2002) have determined that the GSI is a good indicator of gonadal enzymatic activity. However, given the lack of research on PNA or related SPAs, no other studies have reported any change in GSI or gonad mass so far.…”

N-phenyl-1-naphthylamine (PNA) Accumulates in Snapping Turtle (Chelydra serpentina) Liver Activating the Detoxification Pathway

Substituted phenylamine antioxidants (SPAs) are used in Canadian industrial processes. SPAs, specifically N-phenyl-1-naphthylamine (PNA), have received very little attention despite their current use in Canada and their expected aquatic and environmental releases. There is a research gap regarding the effects of PNA in wildlife; therefore, Chelydra serpentina (common snapping turtle) was studied due to its importance as an environmental indicator species. A chronic experiment was performed using PNA spiked food (0 to 3446 ng/g) to determine its toxicity to juvenile C. serpentina. A significant increase in cyp1a mRNA level was observed in the liver of turtles exposed to 3446 ng/g PNA, suggesting that phase I detoxification is activated in the exposed animals. Additionally, a significant decrease in cyp2b transcript level was observed at the two lowest PNA doses, likely indicating another metabolic alteration for PNA. This study helped determine the molecular effects associated with a PNA exposure in reptiles.
