Abstract.Dry weight (W), carbon (C), nitrogen (N), and energy (E) (calculated) accumulation were measured in the estuarine grass shrimp, Palaemonetes pugio, throughout larval development and during the first 2 weeks as postlarvae in seawater over sediment containing the pyrethroid insecticide fenvalerate (SCF; nominal concentrations of 1, 10, and 100 μg fenvalerate kg−1 sediment). The influence of fenvalerate-laden sediment on shrimp growth and utilization patterns of C, N, and E was dependent… 

Ecdysteroid Responses of Estuarine Crustaceans Exposed Through Complete Larval Development to Juvenile Hormone Agonist Insecticides1

Test the hypothesis that the mortality, inhibition of development and decreased fecundity reported previously in these animals from JHA exposure coincides with abnormal circulating titers of ecdysteroids, supporting a newly emerging theory that juvenoids possibly act as anti-ecdysteroid through a novel molecular mechanism involving inhibition of ec Dysteroid signaling.

Cypermethrin Toxicity to Aquatic Life: Bioassays for the Freshwater Prawn Palaemonetesargentinus

Results suggest that juveniles of P. argentinus are much more sensitive to CY pollution than other crustaceans, fish, and tadpoles.

A Review of Grass Shrimp, Palaemonetes spp., as a Bioindicator of Anthropogenic Impacts

This paper reviews ecologically based studies, toxicity testing, and sublethal assessments in grass shrimp and shows how they have laid the groundwork for this genus to be an indicator species.

A comparison of the sublethal and lethal toxicity of four pesticides in Hyalella azteca and Chironomus dilutus

Motility served as the most sensitive endpoint in assessing sublethal effects at low concentrations for both species, while growth was a good indicator of toxicity for all four pesticides for H. azteca.

It is demonstrated that chlorothalonil is highly toxic to grass shrimp and that larval grass shrimp would be the most appropriate life stage to use for chlorothsalonil risk assessments since that stage is the most sensitive.

No acute toxicity to Uca pugnax, the mud fiddler crab, following a 96‐h exposure to sediment‐bound permethrin

It is concluded that short term exposure to permethrin‐contaminated sediment does not pose a significant threat to this species or impact respiration and osmoregulation, and increased GST activity allows us to evaluate this enzyme's induction as a generalist biomarker for sediment‐bound pyrethroid exposures.

Multiple stressor effects of methoprene, permethrin, and salinity on limb regeneration and molting in the mud fiddler crab (UCA pugnax)

Chronic, low‐dose exposures to multiple pesticide stressors cause less‐than‐additive effects on U. pugnax growth processes, and males had more protein in their exoskeletons and less gain in body mass, carapace width, and body condition compared to females.

Analysis of gene expression in Homarus americanus larvae exposed to sublethal concentrations of endosulfan during metamorphosis.



Individual effects and interactions of salinity, temperature, and zinc on larval development of the grass shrimp Palaemonetes pugio. I. Survival and developmental duration through metamorphosis

The reduced viability, restricted euryplasticity, and retarded developmental rates of P. pugio larvae developing in media with low-level zinc contamination would limit the distributive properties of the pelagic phase in the life cycle of the species and reduce recruitment both into and out of the parent estuarine population.

Lipid Condition and Survival in Shrimp (Pandalus borealis) Larvae

The results are consistent with the concept that the TAC condition index can be used to forecast, on a relative basis, differential survival among larval groups.
