“…Group testing was used if groups of fish moved t e gether as a group after orientation t o the test unit. Atlantic menhaden formed tight schools and moved together as a unit during these initial experiments; therefore, group testing (10 individuals per group) was used in later experiments (Hall, et al. 1982a).…”

The objective of this investigation was to evaluate the avoidance responses of juvenile striped bass, Morone saxatilis and Atlantic menhaden, Brevoortia tyrannus to bis (tri‐n‐butyltin) oxide. An avoidance responses was exhibited by striped bass at a total organic tin concentration of 24.9 μg/L. Atlantic menhaden exhibited avoidance to total organic tin concentrations of 5.5 μg/L and greater. Atlantic menhaden are generally more sensitive to toxicants than striped bass; therefore, avoidance responses reported in this study are not surprising. It is highly likely that the concentrations of total organic tin that were avoided by the test species in this study were much higher than expected environmental concentrations. Ecologically significant hazards may occur due to potential effects that unperceived or non‐avoided organotin concentrations may have on behavioral responses mediated by chemosensory systems.

Coral reef fish larvae are tiny, exceedingly numerous, and hard to track. They are also highly capable, equipped with swimming and sensory abilities that may influence their dispersal trajectories. Despite the importance of larval input to the dynamics of a population, we remain reliant on indirect insights to the processes influencing larval behavior and transport. Here, we used genetic data (300 independent single nucleotide polymorphisms) derived from a light trap sample of a single recruitment event of Dascyllus abudafur in the Red Sea ( N = 168 settlers). We analyzed the genetic composition of the larvae and assessed whether kinship among these was significantly different from random as evidence for cohesive dispersal during the larval phase. We used Monte Carlo simulations of similar‐sized recruitment cohorts to compare the expected kinship composition relative to our empirical data. The high number of siblings within the empirical cohort strongly suggests cohesive dispersal among larvae. This work highlights the utility of kinship analysis as a means of inferring dynamics during the pelagic larval phase.

Shoaling enhances cadmium avoidance by lake whitefish, Coregonus clupeaformis

We compared the behavioural responses of solitary and shoaling lake whitefish, Coregonus clupeaformis, to Cd solutions, testing the hypothesis that fish are more responsive to contaminant gradients when in a shoal than when alone. The movements of individual fish were tracked in a countercurrent-type trough with clean water on one side, and water containing sequentially increasing Cd concentrations (0.2-125 ug ll') on the other; the tracked fish was either alone, or within a shoal of four fish. We quantified a number of parameters derived from elements of locomotor behaviour and spatial selection (including the percent-time spent on the Cd-treated side) as potential indicators of response. Individuals in shoals responded to Cd more strongly and at lower concentrations than did solitary fish. While this was indicated by stronger avoidance of Cd, other response measures associated with escape behaviour illustrated this difference more clearly. Our results suggest that the social influence of shoaling enhances a fish's ability to respond to the presence of contaminants.
