    A review assessed effectiveness of techniques used to prevent double-crested cormorant Phalacrocorax auritus predation at aquaculture facilities in the Mississippi delta region, USA (Mott & Boyd ), and concluded that there was little good evidence for what worked and what did not. Pyrotechnics, human effigies, gas cannons, and live. management of Double-crested Cormorant (Phalacrocorax auritus, DCCO) damage in Michigan. Increases in the North American DCCO population, and subsequent range expansion have resulted in complaints of DCCO damage to property, aquaculture, and public resources.

    The double-crested cormorant (Phalacrocorax auritus) is a member of the cormorant family of habitat is near rivers and lakes as well as in coastal areas, and is widely distributed across North America, from the Aleutian Islands in Alaska down to Florida and ing 70–90 cm (28–35 in) in length, it is an all-black bird which gains a small double crest of black Class: Aves. Adult double‐crested cormorants require approximately g of fish per day (Hatch and Weseloh ) compared with 1, g for American white pelicans (Ferguson et al. ), and cormorant chicks require an estimated 8–9 kg of food from hatching to fledging (Seefelt and Gillingham ) compared with 68 kg for American white pelican chicks Cited by: 3.

    tance of southern aquaculture on improving body condition and survival of cormorants. Keywords: body condition, body mass, catfish exploitation, double-crested cormorant, omental fat deposits, Phalacrocorax auritus breeding populations has been attributed mainly to the resurgence of forage fish, particularly alewife (Alosa. The double-crested cormorant is an interesting yet controversial bird. T his bulletinis a comprehensive guide to the issues surrounding the double-crested cormorant (Phalacroco-rax auritus), a species that has gener-ated a tremendous amount of interest and controversy in recent years. The information presented is intended to help anglers, fish.

Aquaculture has expanded rapidly in the Southern United States during the past two decades, especially the cultivation of catfish, crawfish, and bait fish.

These fish usually are cultivated on farms with extensive systems of large shallow ponds that are highly susceptible to predation by birds.

The nature and expansiveness of southern aquaculture and the continued growth of cormorant populations limit options for managing depredations on aquaculture farms. Most efforts rely on devices designed to frighten them from ponds and roosts. A science-based initiative to manage double-crested cormorant damage to southern aquaculture / James F.

SUMMARY: Increasing populations of the double-crested cormorant have caused biological and socioeconomic resource conflicts. In Novemberthe U.S. Fish and Wildlife Service (Service or we) completed a Draft Environmental Impact Statement (DEIS) on double-crested cormorant management.

An Integrated Wildlife Damage Management (IWDM) approach would be implemented to reduce DCCO damage to aquaculture, property, and natural resources, and reduce risks to human health and safety in localized situations when it is deemed necessary.

Cormorant damage management (CDM) may be conducted on public and private property in. In this paper we examine the management of human-double-crested cormorant conflicts in urban nature areas using the Leslie Street Spit in Toronto, Ontario as our focal study area.

We examine the management perspectives of various stakeholders and how they shift over time in response to site ecology and stakeholder input. We categorize management Cited by: 7. J. Glahn, M.

of the Double-crested Cormorant (Phalacroc- orax auntus) competing with fishermen, we have many scientific facts, but there are dif- fering opinions about the problem and what can be done about it. Ac the extremes, some say that there is in fact no biological prob- lem; that cormorant predation is minor com- pared to other losses at fish Size: KB.

Not Just For The Birds: Double-Crested Cormorant Population Management In Minnesota Abstract: Phalacrocorax auritus, the Double Crested Cormorant, is under federal pro-tection by the Migratory Bird Treaty Act, but its population in the Great Lakes Basin is growing rapidly. This is resulting in increasing negative con-sequences.

A science-based initiative to manage double-crested cormorant damage to southern aquaculture. Technical Report by USDA, APHIS,NWRC. 40 pp. Additional Information.A mass kill of the island’s naturally occurring Double-crested cormorant population began in and will continue for a number of years.

The plan to almost wipe out the birds on the island was scheduled to be in full swing inbut a CDI legal challenge in federal court delayed it considerably resulting in less than birds being.On average, a cormorant requires around g of food each day, although the weight of fish eaten can vary both from day to day and seasonally.

Cormorants can also damage and scar fish, especially larger specimens which they catch but are unable to swallow. This damage increases the risk of disease, mortality and stress in affected fish.
