چکیده

In a study of sea louse parasites on chum salmon [1], we presented a host–parasite model that incorporates the effect of parasite-mediated predation on host populations. After publication of the original article, we discovered an error in the functional response of the host–parasite model that we wish to correct to prevent it from being repeated if the model is applied to other systems. The host–parasite model presented in equations (3.2) and (3.3) should be corrected to read

Can reduced predation offset negative effects of sea louse parasites on chum salmon?

The impact of parasites on hosts is invariably negative when considered in isolation, but may be complex and unexpected in nature. For example, if parasites make hosts less desirable to predators then gains from reduced predation may offset direct costs of being parasitized. We explore these ideas in the context of sea louse infestations on salmon. In Pacific Canada, sea lice can spread from fa...

Fish farms, parasites, and predators: implications for salmon population dynamics.

For some salmon populations, the individual and population effects of sea lice (Lepeophtheirus salmonis) transmission from sea cage salmon farms is probably mediated by predation, which is a primary natural source of mortality of juvenile salmon. We examined how sea lice infestation affects predation risk and mortality of juvenile pink (Oncorhynchus gorbuscha) and chum (O. keta) salmon, and dev...

Parasitism and food web dynamics of juvenile Pacific salmon

There is an increasing realization of the diverse mechanisms by which parasites and pathogens influence the dynamics of host populations and communities. In multi-host systems, parasites may mediate food web dynamics with unexpected outcomes for host populations. Models have been used to explore the potential consequences of interactions between hosts, parasites and predators, but connections b...

Sea lice escape predation on their host.

Parasites seldom have predators but often fall victim to those of their hosts. How parasites respond to host predation can have important consequences for both hosts and parasites, though empirical investigations are rare. The exposure of wild juvenile salmon to sea lice (Lepeophtheirus salmonis) from salmon farms allowed us to study a novel ecological interaction: the response of sea lice to p...

Predation intensifies parasite exposure in a salmonid food chain

1. Parasites can influence ecosystem structure, function and dynamics by mediating predator–prey interactions. Recurrent infestations of the salmon louse Lepeophtheirus salmonis associated with salmon aquaculturemaymediate interactions between juvenile salmonids. Louse infection increases pink salmon Oncorhynchus gorbuscha susceptibility to predation, resulting in the trophic transmission of li...
