Sensitivity of fish embryos to weathered crude oil: Part I. Low‐level exposure during incubation causes malformations, genetic damage, and mortality in larval pacific herring (Clupea pallasi)
TLDR
The conclusion that EVO caused significant damage to herring in PWS is supported and previous demonstration by the laboratory that most malformed or precocious larvae die corroborates the decreased larval production measured after the spill.
A Decapod Hemocyte Classification Scheme Integrating Morphology, Cytochemistry, and Function.
TLDR
Examination of the hemocytes of three decapod crustaceans is examined and a classification of these cells is proposed based on morphology, cytochemistry, and studies of cell functions to facilitate the understanding of the physiological roles of their hemocytes.
Histopathology and cytogenetic evaluation of Pacific herring larvae exposed to petroleum hydrocarbons in the laboratory or in Prince William Sound, Alaska, after the Exxon Valdez oil spill
TLDR
Following the 1989 Exxon Valdezoil spill in Prince William Sound, Alaska, USA, Pacific herring larvae sampled from oiled sites had ascites, pericardial edema, and genotoxic damage, which were confirmed to be consistent with oil exposure.
Pacific herring (Clupea pallasi) embryo sensitivity to Prudhoe Bay petroleum hydrocarbons: laboratory evaluation and in situ exposure at oiled and unoiled sites in Prince William Sound
TLDR
Il n'existe pas de preuve categorique que les sites pollues par le petrole exposent les embryons de hareng a des dangers a long terme ou menacent la survie des larves, mais the resultats obtenus dans le cadre of ces travaux justifient la tenue d'une etude in situ de portee plus etendue.
Genetic and Molecular Ecotoxicology: A Research Framework
TLDR
A synthesis of the ideas discussed throughout the Napa Conference on Genetic and Molecular Ecotoxicology is presented, including definitions of important concepts in the field and critical research needs and opportunities.
Clearance of bacteria injected into the hemolymph of the ridgeback prawn, Sicyonia ingentis (Crustacea: Decapoda): Role of hematopoietic tissue
TLDR
The organ‐specific effectiveness of bacterial clearance was determined and found the hematopoietic nodules of the shrimp Sicyonia ingentis to be the most effective on a per gram basis and suggestions that hemocytes in the HPN are functionally mature and held in reserve until they are released into circulation are supported.
Sublethal effects of the (Exxon Valdez) oil spill on herring embryos and larvae: morphological, cytogenetic, and histopathological assessments, 19891991
TLDR
L'importance des degâts morphologiques et cytogenetiques a ete mise en correlation avec l'exposition au petrole chez des moules indigenes de the baie.
Histologic and skeletal abnormalities in benzo(a)pyrene-treated rainbow trout alevins
TLDR
Test alevins had a significantly higher incidence of skeletal malformations in the skull and vertebral column, and abnormalities of vertebral arcualia often corresponded to areas of kyphoscoliotic flexures.
Synthesis of the toxicological impacts of the Exxon Valdez oil spill on Pacific herring (Clupea pallasi) in Prince William Sound, Alaska, U.S.A.
TLDR
It is concluded that 25–32% of the embryos were damaged in PWS in 1989 and oil-induced mortality probably reduced recruitment of the 1989 year class into the fishery, but was impossible to quantify because recruitment was generally low in other Alaskan herring stocks.
CYTOCHEMICAL FEATURES OF SHRIMP HEMOCYTES.
TLDR
Cytochemical features of ridgeback prawn hemocytes were studied using specific stains for lysosomes, cytoplasmic contents, and granule enzymes to facilitate the differentiation of cell types in the ridgebacks and provide information on the functions of and relation ships among different cell types.
