“…Most non-guarded females displayed the N-type pattern, which was considered to be a primary stage in the reproductive series (period 1 or before, de Gaudemar and Beall 1999). In contrast, almost half of the guarded females displayed the M-type pattern (period 2, de Gaudemar and Beall 1999).…”

“…However, the N-type satellite might be a form of "dominant male mimicry" -sometimes, an N-type satellite was seen alongside the female while the true dominant was away from the nest, chasing away other satellites. When there was a relatively long time before the dominant returned to the nest, the satellite remained slightly downstream of the female and approached her frequently while vibrating its body, which are typical behaviours of a paired male (Kimura 1972;Satou et al 1991;de Gaudemar and Beall 1999). As female oviposition is more likely to be triggered by the N-type male guard than an M-type male, such a tactic might compensate for the disadvantage of displaying the N-type pattern.…”

“…It is not clear why females displayed the melanic pattern with the approach of oviposition, but it may be a spawning signal for successful fertilization. A stimulus based on visual as well as behavioural cues (Satou et al 1991(Satou et al , 1994ade Gaudemar and Beall 1999) might be essential for increasing spawning motivation and synchronising gamete release.…”

We observed transient status-dependent female mimicry related to reproductive behaviour in landlocked red-spotted masu salmon (Oncorhynchus masou ishikawae). In females, the lower half of the lateral flank underwent solid blackening as an ovipositional character, and 70% of subordinate males showed a similar lateral pattern (M-type). In contrast, most of the paired males and 30% of subordinate males showed a different lateral pattern in which a melanic stripe ran along the lateral-line organ (N-type). It was possible to bring an M-type pseudo-fish model into closer proximity to a pair than an N-type model. In addition, the rate of successful sperm release in subordinate M-type males was higher than that in subordinate Ntype males. Males could transform between N-and M-types according to fluctuations in competitive status among the males. A digital video image related to the article is available at

“…The experiment was conducted in a semi-natural channel beside Lapitxuri stream, a tributary to the Nivelle River in south-western France (+43°16'59", -1°28'54") (De Gaudemar and Beall 1999). Behavioral observations and offspring sampling were performed from November 2012 to the end of March 2013, which corresponds to brown trout spawning season under this latitude.…”

With our powers combined: integrating behavioral and genetic data to estimate mating success and sexual selection

The analysis of sexual selection classically relies on the regression of individual phenotypes against the marginal sums of a males × females matrix of pairwise reproductive success, assessed by genetic parentage analysis. When the matrix is binarized, the marginal sums give the individual mating success. Because such analysis treats male and female mating/reproductive success independently, it ignores that the success of a male × female sexual interaction can be attributable to the phenotype of both individuals. Also, because it is based on genetic data only, it is oblivious to unproductive matings, which may be documented by behavioral observations. To solve these problems, we propose a statistical approach which combines matrices of offspring numbers and behavioral observations. It models reproduction on each mating occasion of a mating season as three stochastic and interdependent pairwise processes, each potentially affected by the phenotype of both individuals and by random individual effect: visit of a female by a male, concomitant gamete emission, and offspring production. Applied to data from a mating experiment on brown trout, the model yielded different results from the classical regression analysis, with only a negative effect of female body size on the probability of visit and gamete release, while the classical approach based on regression found a positive effect of male size on the number of both visits and offspring, and no effect of female size. Because the general structure of the model can be adapted to other partitioning schemes of the reproductive process, it can be used for a variety of biological systems where behavioral and genetic data are available.

“…These results validate the observations of others who also used dummies to investigate salmonines spawning behaviour (Newcombe and Hartman 1980;Satou et al 1987Satou et al , 1991Satou et al , 1994Foote et al 2004). The entire Salmoninae spawning process can be understood as a long chain of inter-related FBPs that run in increased intensity leading to gamete release (Tautz and Groot 1975;Satou et al 1987;1994;de Gaudemar and Beall 1999;Berejikian et al 2000).…”

Two examples of fixed behavioural patterns in salmonines: female false spawning and male digging

Data collected from underwater video recordings in the wild and in a semi-natural channel were used to study two examples of relatively unknown behaviour in the Salmoninae subfamily -false spawning in females and digging in Oncorhynchus males. Observations suggest that false spawning should be regarded as an incomplete fixed behavioural pattern (FBP) and that male digging represents two special types of FBP (displacement FBP) with threatening and courting functions as ultimate causes.
