“…For example, fishes such as salmon form and retain memories of the odor cues associated with their place of birth in a process called olfactory imprinting (Hasler and Scholz, 1983). This olfactory imprinting then contributes to the fishes' successful return to reproduce at their stream of birth after several years at sea.…”

To initiate a genetic analysis of olfactory development and function in the zebrafish, Danio rerio, we developed a behavioral genetic screen for mutations affecting the olfactory sensory system. First, we characterized olfactory responses of wild-type zebrafish to various odors. We found that 3-day-old juvenile zebrafish reacted to the amino acid L-cysteine with an aversive behavioral response. We isolated one mutant, laure (lre), which showed no aversive behavioral response to L-cysteine at 3 days of development, and carried out a preliminary characterization of this mutant's defects. We found that lre mutant fish were also defective in their response to L-serine and L-alanine, but not to taurocholic acid, as young adults. In addition, lre mutant fish had significantly fewer primary olfactory sensory neurons than normal, and the axons of these neurons did not form the characteristic axon termination pattern in the developing olfactory bulb. Nevertheless, the olfactory epithelium of lre mutant fish showed normal or near normal electrophysiological responses to several odorants. Our data suggest that the behavioral defects observed in the lre mutant result from the disruption of the developing olfactory sensory neurons and their axonal connections within the olfactory bulb. The isolation of the lre mutant shows that our behavior-based screen represents a viable approach for carrying out a genetic dissection of olfactory behaviors in this vertebrate model system.

Identification of an olfactory imprinting-related gene in the lacustrine sockeye salmon, Oncorhynchus nerka

The olfactory system of salmonids is essential for imprinting and the subsequent homing migration. Olfactory imprinting-related genes were identified in the olfactory system of 1-and 3-year-old lacustrine sockeye salmon (Oncorhynchus nerka) using a subtractive hybridization technique of representational difference analysis (cDNA-RDA). We have obtained a partial clone from a subtractive cDNA library of 1-year-old fish that contains a 756 bp open reading frame coding for a putative protein with 252 amino acid residues named the Sockeye salmon Olfactory system Imprinting related Gene (SOIG). By northern hybridization, the SOIG mRNA was only expressed in the olfactory epithelium and not in other tissues. In situ hybridization showed that the expression of SOIG mRNA was observed in the olfactory receptor cells and basal cells of the olfactory epithelium. This suggests that SOIG could have specific and important roles in olfactory system.

“…Nordeng (1977) proposed that a genetically based pheromone, released by juvenile salmonids, could be used as a basis for homing by adults. Later, Hasler & Scholz (1983) indicated that an innate attraction to a conspecific pheromone could be acting in concert with olfactory imprinting, to guide salmonids to natal waters. Several studies have since documented chemosensory recognition of conspecifics in several orders of fish, including the Salmoniformes (Quinn & Busack 1987;van Havre & Fitzgerald 1988;Kelley 1989;Olsen 1989).…”

Galaxias maculatus dominated the whitebait catch in 11 of the 12 Bay of Plenty rivers studied. In four rivers, this species accounted for 84-99% of the catch. However, in seven other rivers, G. maculatus accounted for only 52-70% of the catch, and major (>18%) contributions were made by either Galaxias brevipinnis or Galaxias fasciatus. hi the twelfth river, the Motu River, G. brevipinnis dominated the catch, accounting for over 70% of whitebait caught. This is the first report of a rivermouth whitebait fishery dominated by G. brevipinnis. Rivers where G. brevipinnis contributed more than 18% of the catch were all within a 70 km radius west of the Motu River mouth. In rivers beyond this limit, G. brevipinnis was less than 2% of the catch. Such differences in species composition may result from river-mouth selection by migratory juveniles of G. brevipinnis.
