This study was conducted to evaluate the potential of water hyacinth as aquafeed for grass carp (Ctenopharyngodon idella). Fish were stocked in eight glass aquaria at 20 fish per aquaria. Three iso-proteinous diets (30% crude protein (CP)) were prepared with the addition of different parts of sun-dried water hyacinth, that is, whole plant meal diet (WPM), leaf meal diet (LM) and root meal diet (RM), along with control diet. Results revealed significant (P ≤ .05) differences in weight gain and length among treatments. Higher weight gain was observed in LM and lower in RM diets. CP contents of fish fed WPM were significantly higher (P ≤ .05), followed by LM than RM and control diets. Crude fat was significantly higher in fish fed RM followed by LM, while ash contents were significantly higher in control. Nutrient digestibility in the case of CP was significantly higher (P ≤ .05) for WPM, LM and control groups than RM, while fat digestibility was significantly higher (P ≤ .05) in RM diet followed by LM than WPM and control. Histological study showed no significant variations in liver and kidney. In conclusion, LM-based diets were found to be most suitable without any adverse effects on the histopathological disorders in experimental fish.

Although, use of animal species in disease treatment and culture practices is as ancient as that of plant species; however ethnomedicinal uses and cultural values of animal species have rarely been reported. Present study is the first report on the medicinal uses of mammals and bird species in Pakistan. Questionnaires and semi-structured interviews were applied to collect qualitative and quantitative data from local informants (N = 109). Relative frequency of mention (RFM), fidelity level (FL), relative popularity level (RPL), similarity index (SI) and rank order priority (ROP) indices were used to analyzed the data. One hundred and eight species of animals, which include: 83% birds and 17% mammals were documented. In total 30 mammalian and 28 birds’ species were used to treat various diseases such as rheumatic disorders, skin infections and sexual weakness among several others. Fats, flesh, blood, milk and eggs were the most commonly utilized body parts. Bos taurus, Bubalus bubalis, Capra aegagrus hircus, Felis domesticus, Lepus nigricollis dayanus and Ovis aries (mammals) and Anas platyrhynchos domesticus, Columba livia, Coturnix coturnix, Gallus gallus and Passer domesticus (birds) were the highly utilized species. Medicinal and cultural uses of 30% mammals and 46% birds were reported for the first time, whereas 33% mammals and 79% birds depicted zero similarity with previous reports. Present study exhibits significant ethnozoological knowledge of local inhabitants and their strong association with animal species, which could be helpful in sustainable use of biodiversity of the region. Additionally, in vitro and in vivo evaluation of biological activities in the mammalian and birds’ species with maximum fidelity level and frequency of mention could be important to discover animal based novel drugs.

| This study was conducted to evaluate the socio-economic status of fishermen community at Rivers of Pakistan in South Punjab. Head Taunsa and Punjnad were selected as study sites to collect information from fishermen through well prepared questionnaire. It was observed fishermen in both study sites were of 20 -55 year of age having maximum family size of 7-10 individuals. Illiterate fishermen were recorded to be 50 and 40 % at head Punjnad and Taunsa, respectively. Fishermen maximum yearly income at both study sites were in the range of 70,000 - 80,000 PKR (Pakistan rupees). The study had confirmed most of the fishermen were living in poor conditions which accounts 60 and 80 % of head Punjnad and Taunsa, respectively. However, most of them were dependent on tap as well as tube well water as drinking source. On the other hand, to run the fishing business, majority of them were relying on loans from non-government sources. It is concluded that fishing is a profitable business but with educating the fishermen especially in fish handling could improve their status of living as well as in generating brilliant mind towards global economy.
