An evaluation of the effects of three marking techniques on the growth, behavior, and mortality of channel catfish (Ictalurus punctatus (Rafinesque)

Three groups of fingerling channel catfish, Ictalurus punctatus (Rafinesque), were marked using either a partial fin clip of the left pelvic fin, a cold brand using liquid nitrogen at -196°C as a coolant, or a gun-injected spaghet-ti-type floy tag. Fish were observed during a 12-week period and compared to a control group for loss of marks, noticeable change in behavior, mortality attributed to the marks, and any significant effect that the marks exhibited on growth. It was determined that the cold brand was the only marking technique producing a mark that was still retained by the fish and recognizable after a 12-week period. Behavior was greatly altered only in the group receiving the injected tag; this group also exhibited the only substantial rate of mortality attributed to the mark. Statistical analysis of the effects of the three marking techniques on growth indicated that the application of the marks had no significant effect on those fish surviving throughout the experimental period

“Writing a Name in the Sky”: Rancière, Cavell, and the Possibility of Egalitarian Inscription

Democratic theory is often portrayed as torn between two moments: that of disruption of rule, and the ordinary, ongoing institutionalization of politics. This dualism also marks contemporary democratic theory. In Jacques Rancière's theory of politics it takes the form of an emphasis on the ruptural qualities of the staging of novel democratic demands and the reconfiguration of the space of political argument. The reconfiguration of existing political imaginaries depends upon a moment of inscription, which remains underdeveloped in Rancière's work. Arguing that the possibility of inscription is indeed thematized in Rancière's more historical writings, but is often ignored by commentators, this article seeks to draw out the implications of a focus on inscription for democratic theory and practice. To flesh out this account, the article draws on Cavell's writings on exemplarity and the role of exemplars in fostering both critical reflection and the imagination of alternatives. The focus on such exemplars and an aversive, nonconformist ethos together facilitate a better understanding of what is required for such novel demands to be acknowledged and inscribed into democratic life.</jats:p
