A REVIEW OF THE IMPACT OF GREAT CORMORANT (Phalacrocorax carbo sinensis) ON THE FISH STOCK [PDF]
Croatian Journal of Fisheries, 2014 The objective of this review is to present research on the impact of great cormorant on the fish stock and aquaculture in order to advance knowledge of the problem. In recent years, there has been an increasing awareness of the effect of fisheries on bird populations, and vice versa.

Underwater hearing in the great cormorant (Phalacrocorax carbo sinensis): Methodological considerations [PDF]
Proceedings of Meetings on Acoustics, 2016 The underwater hearing threshold of a great cormorant (Phalacrocroax carbo sinensis) was measured at 2 kHz using psychophysical methods. Previous in-air and underwater testing suggests that cormorants have rather poor in-air hearing compared to other birds of similar size (Johansen, 2016).

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.

Microchemical provenancing of prey remains in cormorant pellets reveals the use of diverse foraging grounds. [PDF]
J Wildl Manage, 2022 Microchemical provenancing was successfully applied to otoliths exposed to digestion by piscivorous birds and it was possible to clarify on a small scale from which waterbodies or habitat clusters the birds obtain their food. By the use of prey provenancing, site‐specific management plans can be developed and the effect of management measures on ...

Cormorant catch concerns for fishers: estimating the size-selectivity of a piscivorous bird. [PDF]
PLoS ONE, 2013 Conflict arises in fisheries worldwide when piscivorous birds target fish species of commercial value. This paper presents a method for estimating size selectivity functions for piscivores and uses it to compare predation selectivities of Great ...
