    Darwin Initiative for the Survival of Species Annual Report 1. Darwin Project Information Project title Establishment of Penguin Monitoring Programme Country(ies) Chile Contractor Environmental Research Unit Project Reference No. 162/9/007 Grant Value £10,350 p.a. for 3 years Start/Finishing dates April 2001 to March 2004 Reporting period April 2003 2. Project Background • Briefly describe the location and circumstances of the project and the problem that the project aims to tackle. The project takes place on Magdalena Island, near the city of Punta Arenas in southern Chile. Magdalena Island is one of Chile’s most important breeding sites for Magellanic penguins, a species whose global distribution is restricted to southern South America. Best guess estimates put the current world population of Magellanic penguins at around 1.5 million breeding pairs, with approximately 700,000 pairs in Chile, 650,000 pairs in Argentina and 150,000 pairs in the Falkland Islands (Bingham 1998, Bingham & Mejias 1999, Gandini et al. 1998). Population studies in the Falkland Islands conducted by Mike Bingham have revealed an 80% decline in Magellanic penguins between 1990/91 and 2002/03. A reduction of fish and squid resulting from large-scale commercial fishing appears to be the cause of the penguin decline, through reduction of foraging rates, breeding success and juvenile survival (Bingham 2002). Population studies conducted in Argentina show evidence of decline at some colonies, but not all (Boersma 1997). Declines in Argentina appear to be largely the result of high adult and juvenile mortality caused by oil pollution. An estimated 40,000 Magellanic penguins are killed by oil pollution every year along the coast of Argentina, representing the main cause of adult mortality (Gandini et al.

    International Journal of Science and Research (IJSR) ISSN (Online): 2319-7064 Impact Factor (2012): 3.358 Food and Feeding Habits of Two Freshwater Catfish, Mystus cavasius and Xenentodon cancila from Chambal River (M.P) Jaya Chaturvedi1, Deepa Singh Parihar2 1, 2 Aquatic Biology Laboratory, Jiwaji University Gwalior (M.P.), India Abstract: The food and feeding habits of freshwater catfish, Mystus cavasius and Xenentodon cancila were analysed on the basis of methods i.e., percent numerical count and percent frequency occurrence. The results from the analysis of gut contents of these two fresh water catfishes shows that both of the fish, M. cavasius and X. cancila depends mainly on the animal material i.e., zooplankton, crustaceans, round worms, insects, parts of insect, insects larvae and mollusc. The results from the study also reveal that plant material contributes the equal portion of the diet. M. cavasius has been categorised as eury-omnivorous as it feeds on wide range of diet including both the vegetable as well as animal diet but on the basis of biomass of food material, animal material contributes a major portion of the diet hence it may be pointed out as carnivore in its feeding habit. The gut contents of X. cancila consist of large portion of animal material in biomass and plant materials is in lesser proportion hence this comes in the category of carnivorous fish. Empty stomach were observed in May and June (pre-spawning period) due to bigger size of the gonads which occupying larger space in the body cavity and allowed a little space for the food.

    Chapter 2.9 — Freshwater birds: identification, rehabilitation and management• 193 2.9 Waterbirds: identification, rehabilitation and management Phil Straw Avifauna Research & Services Australia Abstract All waterbirds and other bird species associated with wetlands, are described including how habitats are used at ephemeral and permanent wetlands in the south east of Australia. Wetland habitat has declined substantially since European settlement. Although no waterbird species have gone extinct as a result some are now listed as endangered. Reedbeds are taken as an example of how wetlands can be managed. Chapter 2.9 — Freshwater birds: identification, rehabilitation and management• 194 Introduction such as farm dams and ponds.
