APPLICATION OF THE GREAT CORMORANT'S (Phalacrocorax carbo sinensis) DAILY MEAL IN THE STIMATION OF DAMAGES AT FISHPONDS [PDF]

Croatian Journal of Fisheries, 2004
Daily meal of the Great Cormorant (Phalacrocorax carbo sinensis), joined with the number of birds and composition of fish in the meal, has high importance in total calculation of damage-costs on fish stock.

When is the bait worth the risk? A mechanistic model of a compensatory ecological trap in seabirds

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological traps occur when organisms preferentially select habitats that reduce fitness. In seabird–fishery systems, fishery‐derived trophic subsidies can increase foraging success, reinforce habitat preference and indirectly enhance reproductive output or recruitment,

Seasonal variations in numbers of great cormorant (Phalacrocorax carbo) on the Kolut fish farm (nw Serbia) [PDF]

Archives of Biological Sciences, 2006
Seasonal variations in numbers of great cormorant were studied between 1998 and 2004 on ponds of the Kolut fish farm (NW Serbia). Its presence is not detected only during winter. Spring migration culminates in early March.

Investigation of Commensal Escherichia coli Populations of Cormorant Hatchlings in the Absence of Anthropogenic Impacts in Remote Areas of West Mongolia

Microorganisms, 2021
To increase our understanding of bacterial intestinal colonization in animal populations lacking substantial anthropogenic influence we studied the diversity of E. coli in cormorants from the pristine West-Mongolian steppe. E.

Waterbird zoogeochemical effects shape wetland nutrient dynamics and algal communities in Laurentian Great Lakes coastal freshwater wetlands

Journal of Animal Ecology, EarlyView.
Distinct waterbird species influence nutrient cycling through guano contributions in Great Lakes coastal wetlands. Waterbird‐derived nutrients favour distinct algal communities and wetland sediments rapidly remove waterbird nutrients via biogeochemical processes.

An Updated Ecology of Atlantic Salmon (Salmo salar) at Sea

Fisheries Oceanography, EarlyView.
ABSTRACT Atlantic salmon have had a key role in European and North American oceans and human societies. Salmon are exploited and observed in rivers and along coasts, but there has always been great interest in knowing where salmon are going when they are at sea.

Effects of researcher disturbance on Double-crested Cormorant nest survival

Journal of Field Ornithology
Demographic data on avian species are critically important for conservation and management. Research on avian demography often requires some level of human disturbance at nest sites.

Northern range shift may be due to increased competition induced by protection of species rather than to climate change alone

Ecology and Evolution, 2018
Few long‐term, large‐scale studies have been conducted about the factors likely to explain changes in species abundance and distribution in winter. Range shifts are generally attributed to the climate change or land use.

Pejerrey (Odontesthes bonariensis) Under Siege: Main Infectious Diseases and Their Role in Aquaculture and Wild Populations Amidst Environmental Change

Journal of Fish Diseases, Volume 48, Issue 4, April 2025.
ABSTRACT The pejerrey (Odontesthes bonariensis) is a key species for recreational and commercial fisheries in Argentina and holds significant aquaculture potential. It has been introduced to various countries worldwide, including Japan, where intensive aquaculture has developed.
