This short review will focus on selected aspects of the biology of eyeflukes in fishes and will highlight those areas where there are clear lacunae in the authors' knowledge that warrant further exploration.
Identification and preliminary characterization of a chitinase gene in the Autographa californica nuclear polyhedrosis virus genome.
Phylogenetic analyses indicate that AcMNPV, or an ancestral baculovirus, acquired the chitinase gene from a bacterium via horizontal gene transfer.

The epidemiology of diplostomiasis in farmed rainbow trout from north-east Scotland
It is indicated that it is possible by regular cleaning and use of molluscicides to keep the intensity of diplostomiasis at such a level that rainbow trout do not become severely affected, but as with other parasitic diseases, a combination of control methods will probably be required to eradicate the disease completely from trout farms.
Studies on the infectivity of Diplostomum spathaceum in rainbow trout (Oncorhynchus mykiss)
The optimum age of infectivity for cercariae was between 0–5 h after liberation from the snail and for intraperitoneally injected diplostomules, 5 h post-transformation in vitro through fish skin.
Cercariae and diplostomules of Diplostomum spathaceum (Digenea) elicit an immune response in rainbow trout, Salmo gairdneri Richardson
The immune response of rainbow trout to cercariae and diplostomules of Di Plostomum spathaceum was investigated and sera were tested for their cross-reactivity with the other larval stage, using an ELISA.
Protection of rainbow trout, Oncorhynchus mykiss (Richardson), against Diplostomum spathaceum (Digenea): the role of specific antibody and activated macrophages
An antibody–dependent cell–mediated cytotoxic (ADCC) mechanism is proposed, conferring protection in immunized fish, supported by the finding that cercarial and diplostomule antigens are capable of activating macrophages in Immunized rainbow trout.
Diplostomum spathaceum (Rud. 1819): effects of physical factors on the infection of rainbow trout (Salmo gairdneri) by cercariae
Within the confines of the flume, it was possible to control the infection rate of trout with D. spathaceum cercariae by manipulating flow rate, suggesting that it may be a possible method of controlling diplostomiasis on fish farms.
