“…Atlantic croaker larvae ( Micropogonias undulatus , a species closely related to red drum) exposed to DDT through maternal transfer displayed lower mean and maximum response speeds to a visual predatory stimulus and had impaired routine swimming activity until oil globule absorption [19]. Atlantic croaker larvae exposed to maternally transferred Aroclor 1254 had slower growth and reduced responsiveness to a vibratory stimulus [20]. Maternally transferred methylmercury induced a variety of effects on M. undulatus routine and escape behaviors [21].…”

Malathion is a highly soluble organophosphate insecticide that is widely used in agriculture and mosquito eradication campaigns. Fish species, such as red drum (Sciaenops ocellatus), that use seagrass beds as nursery areas could be affected by runoff waters contaminated with malathion. We exposed red drum larvae at the size they reach in estuarine nursery areas to environmentally realistic and sublethal levels of malathion (0, 1, and 10 microg/L). We evaluated the effects of such exposure on ecologically significant behaviors (routine swimming and predator evasion), growth, and resting metabolism. Malathion exposure to relatively low but ecologically realistic concentrations did not affect routine behavior, escape behavior, resting metabolic rate, or growth, indicating that reported environmental levels may be safe for young fishes. However, a recent substantial increase in the use of malathion may elevate surface-water concentrations to levels above those tested in the present study.

“…Detection of pressure change on one side of the body elicits contraction of muscles on the opposite side of the body, thus moving the fish rapidly away from the point of stimulus (Abrahams, 2006). Toxicant interference with this C‐start response could, therefore, have implications for predator avoidance and ability to respond to a stimulus can be used as an indicator of toxicant exposure (McCarthy et al , 2003; Weber, 2006; Painter et al , 2009; Stanley et al , 2009; Rice et al , 2011). Toxicants may also interfere with visual function and inherent visual reflexes in early life stages which can be detected by monitoring the optomotor response (OMR), the locomotor behaviour of an animal induced in response to a repetitive pattern (Richards et al , 2008).…”

The use of early life stages of fishes (embryos and larvae) in toxicity testing has been in existence for a long time, generally utilizing endpoints such as morphological defects and mortality. Behavioural endpoints, however, may represent a more insightful evaluation of the ecological effects of toxicants. Indeed, recent years have seen a considerable increase in the use of behavioural measurements in early life stages reflecting a substantial rise in zebrafish Danio rerio early life-stage toxicity testing and the development of automated behavioural monitoring systems. Current behavioural endpoints identified for early life stages in response to toxicant exposure include spontaneous activity, predator avoidance, capture of live food, shoaling ability and interaction with other individuals. Less frequently used endpoints include measurement of anxiogenic behaviours and cognitive ability, both of which are suggested here as future indicators of toxicant disruption. For many simple behavioural endpoints, there is still a need to link behavioural effects with ecological relevance; currently, only a limited number of studies have addressed this issue. Understanding the physiological mechanisms that underlie toxicant effects on behaviour so early in life has received far less attention, perhaps because physiological measurements can be difficult to carry out on individuals of this size. The most commonly established physiological links with behavioural disruption in early life stages are similar to those seen in juveniles and adults including sensory deprivation (olfaction, lateral line and vision), altered neurogenesis and neurotransmitter concentrations. This review highlights the importance of understanding the integrated behavioural and physiological response of early life stages to toxicants and identifies knowledge gaps which present exciting areas for future research.

“…Significant polychlorinated biphenyl concentrations in white perch were closely related to IS in 14 Chesapeake Bay subestuaries (King et al 2004). Anthropogenic chemicals like polychlorinated biphenyls disrupt endocrine function associated with reproduction in fishes; are associated with depressed survival, malformation, and abnormal chromosome division in eggs and larvae; and are associated with reduced growth and survival skills in larvae (Longwell et al 1992(Longwell et al , 1996Colborn and Thayer 2000;McCarthy et al 2003).…”

We estimated target and limit impervious surface reference points (ISRPs) based on Chesapeake Bay dissolved oxygen (DO) criteria, and we examined associations and relationships among the percentage of watershed in impervious surface (IS), summer DO, and the presence of indicator species (blue crab Callinectes sapidus, white perch Morone americana, striped bass M. saxatilis, and spot Leiostomus xanthurus) in bottom waters of nine brackish subestuaries of Chesapeake Bay. Ideally, a target ISRP represented a level of development that maintained mean bottom DO at 5 mg/L or greater, while an ISRP threshold represented development that degraded mean bottom DO to less than 3 mg/L. The proportion of bottom trawls containing each indicator species rapidly declined from about 0.40 to 0.10 when DO fell below 3 mg/L, whereas the proportion remained at about 0.50 when DO was above 5 mg/L. The IS percentage had a significant negative influence on mean bottom DO and the odds that indicator species were present in midchannel bottom waters (0.8-7.0 m deep). Watersheds at or below a target IS of 5.5% (rural watershed) maintained mean bottom DO above 3 mg/L, but mean DO was only occasionally at or above 5 mg/L. Mean DO seldom exceeded 3 mg/L in watersheds with an IS value above 10% (suburban threshold). Comprehensive watershed management will be needed to offset significant degradation of bottom-water fish habitat in brackish subestuaries if rural lands are converted to suburban areas.
