German term or phrase: Fraßdruck
From an environmental impact study for a planned offshore windpower project:

Während der Bauphase wird es zu Umlagerungen von Sediment und damit zur Beeinflussung der Benthoslebensgemeinschaften kommen. Dies kann in der Folge zu Veränderungen in der Nahrungssituation der Fische und der darauf aufbauenden Nahrungskette führen. Diese Auswirkungen sind aber zeitlich und räumlich begrenzt.
Geräuschemissionen können andererseits dazu führen, dass einige Arten vertrieben werden, sich der *Fraßdruck* auf andere Arten dadurch verringert und sich diese vermehrt ansiedeln.

predation pressure


Explanation:
Die Seepocken zeigen ausgeprägte Populationsschwankungen, wofür insbesondere der Fraßdruck verantworlich erscheint.

The barnacles show pronounced population oscillations which appear to
result from predation pressure.

aggressive voraciousness of fish


Explanation:
Insbesondere für die Rettung der Äsche ist auch eine gezielte Vergrämung des Gänsesägers nötig. Die Ergebnisse des Artenschutzprogramms Äsche haben unstrittig belegt, dass gerade der Fraßdruck dieses Vogels eine Erholung der Äschenbestände behindert. Deshalb warten wir mit wachsender Ungeduld, dass die ursprüngliche Zusage der Minister Miller und Schnappauf eingelöst wird, an den betroffenen Untersuchungsgewässern, zu denen in Schwaben die obere Iller zählt, durch eine begrenzte letale Vergrämung des Gänsesägers das biologische Gleichgewicht zwischen Fisch und Vogel wieder herzustellen.

An aggressive and voracious fish, it poses a threat to other forms of aquatic life. Population is now estimated in the millions. ...

disagree  Cetacea: "Frassdruck" is a neutral term. These species are neither being voracious nor aggressive, they're simply feeding to sustain themselves. But by doing so, they exert pressure on other species depending on the same food sources.

predatory pressure


Explanation:
Another possibility, but see the following:

"Most mirids are general rather than specific predators and provide PREDATORY PRESSURE on a broad range of pest species in an orchard but there are highly host specific exceptions."

(http://www.virginiafruit.ento.vt.edu/mirids.html)

"Since the lesser weever feeds mainly on fish (85.6%), almost exclusively on gobies (Pomatoschistus sp.), and with an assumed transfer efficiency of approximately 10%, the indirect PREDATORY PRESSURE exerted by it may amount to 1.6 6.7g AFDW-m^2 x year^-1."

(See Web page for properly formatted mathematical expressions:
http://www3.interscience.wiley.com/journal/119432189/abstrac...

Many others.
