“…Selection for strains resistant to diseases has become a major goal of salmonid farming, and intraspecific selection for fish resistant to various diseases has been attempted (reviewed by Price 1985, Chevassus & Dorson 1990, Fjalestad et al 1993. Encouraging results have been published concerning IHN (Amend & Nelson 1977, McIntyre & Amend 1978 and IPN (Okamoto et al 1993) caused by a birnavirus.…”

The purpose of this review is to introduce surrogate production as a new technique for fish-seed production in aquaculture. Surrogate production in fish is a technique used to obtain the gametes of a certain genotype through the gonad of another genotype. It is achieved by inducing germ-line chimerism between different species during early development. Primordial germ cells (PGCs) are a key material of this technique to induce germ-line chimera. In several species, it has been reported that PGCs differentiated from the blastomeres inherited some maternally supplied mRNA located at the terminal regions of the early cleavage furrows. PGCs from donor species (or strains) are isolated and transplanted into host species to induce the germ-line chimera.Four methods for inducing germ-line chimera, namely, blastomere transplantation, blastoderm-graft transplantation, transplantation of PGC from the genital ridge and transplantation visualized PGC with GFP fluorescence, are described. Several problems preventing the successful induction of germ-line chimera in various fish species are mentioned. Surrogate production, however, has the possibility to allow efficient fish-seed production and effective breeding and transfer of biodiversity to an aquaculture strain.Conservation and efficient utilization of genetic resources will be achieved through surrogate production combined with the cryopreservation of PGCs.

“…This needs to be investigated. Genetic variation of susceptibility and resistance to disease has often been found both between and within host populations (Price, 1985;Chevassus & Dorson, 1990) including genetic variation in behaviour (Yan, Stevens & Schall, 1994). However, there may be additive genetic variation in physiology but no such variation in discriminative feeding behaviour (Berenbaum & Zangerl, 1992).…”

S U M M A R YMany parasites that use intermediate hosts are transmitted t o the next host through predation. If the next host's fitness is strongly reduced by the parasite, it is under selection either to recognize and avoid infected intermediate hosts or to exclude that prey species from its diet when alternative prey are available. We investigated the predator-prey interaction between laboratory bred three-spined sticklebacks (Gasterosteus aculeatus), the second intermediate host of the cestode Schistocephalus solidus, from 2 parasitized and 1 unparasitized population, and different prey types: infected and uninfected copepods and size-matched Daphnia as alternative prey. Copepods with infective procercoids were more active, had a lower swimming ability and were easier to catch than uninfected controls. The sticklebacks preferred moving copepods. Therefore parasitized copepods were preferentially attacked and consumed. There was no effect of the sticklebacks' parent population being parasitized or not. The sticklebacks switched from Daphnia to (uninfected) copepods in the course of a hunting sequence; this switch occurred earlier in smaller fish. With this strategy the fish maximized their feeding rate: Daphnia were easier to catch than copepods but increasingly difficult to swallow when the stomach was filling up especially for smaller fish. However, there was no indication that sticklebacks from infected populations either consumed Daphnia rather than copepods or switched later in the hunting sequence to consuming copepods than fish from an uninfected population. Thus, sticklebacks did not avoid parasitized prey although S. solidus usually has a high prevalence and causes a strong fitness reduction in its stickleback host.
