Measurements were made of the swimming and metabolic performance of the Amazonian characin Triportheus angulatus in waters from the Rio Negro and the Rio Solimoks. When allowances for temperature and size of fish were made there was very little difference among groups of fish tested in either type o...

Strips of isolated rat diaphragm muscle were attached to a servomotor–transducer apparatus, and the muscle length was cycled in a sinusoidal fashion about the length at which maximum isometric twitch force was developed, Lo. The amplitude of the length displacement (excursion ...

We investigated the effects of preparing surgical incision sites with a topical antiseptic on wound healing and hematological response in rainbow trout Oncorhynchus mykiss. A povidone–iodine solution was applied both pre- and postsurgery to the incision sites on treated fish. Three-cent...

New neurons are continuously generated in the hippocampus and may play an important role in many physiological and pathological conditions. Here we present evidence of cell proliferation and neurogenesis after a selective and transient excitotoxic injury to the hippocampal cornu ammonis 1 (CA1) area...

Background. Lipoic acid (LA), which has significant antioxidant properties, may also function as a potent neuroprotectant. The synthetic compounds INV-155, INV-157, INV-159, and INV-161 are physiochemical combinations of lipoic acid and captopril. We sought to determine if these compounds have neuro...

Molecular features of cadmium (Cd) and calcium (Ca) uptake and toxicity in rainbow trout liver mitochondria were studied using modulators of mitochondrial permeability transition pore (MPTP), mitochondrial calcium uniporter (MCU) and rapid uptake mode (RaM). Malate-glutamate energized mitochondria w...

Brook charr, Salvelinus fontinafis, shifts its diet from zoobenthos to pelagic prey when living sympatrically with white sucker, Catostomus commersoni, in lakes of the Laurentian Shield. We tested the hypothesis that this diet difference would have a significant impact on their pyloric caecal morpho...

Previous work in our laboratory has provided evidence that preadministration of apocynin and lipoic acid at subthreshold levels for neuroprotection enhanced the neuroprotective capacity when injected in combination. Therefore, the present investigation wa...

Effects of growth acceleration on eye development have been examined in genetically modified salmonids. Growth hormone (GH) transgenic coho salmon (Oncorhynchus kisutch (Walbaum, 1792)) show dramatically elevated ove...

BACKGROUND: Cattle represent a reservoir for Giardia and Cryptosporidium and may contaminate water sources. OBJECTIVES: To determine the distribution of Cryptosporidium and Giardia on dairy farms and in water bodies near the farms. FARMS AND WATER SOURCES: Twenty dairy farms and 20 wells and 13 su...

Emamectin benzoate (EMB; SLICE®) has been the drug of choice for the control of sea lice in salmon aquaculture within the past decade due to its ease of administration as well as efficacy on all parasitic stages of sea lice. This over-reliance has led to increased tolerance to the drug and a conseq...

Either handling or exercise cause an increase in body weight in fish acclimated to fresh water, and a decrease in body weight in fish acclimated to sea water.

Understanding the mechanisms that regulate nephron progenitors during kidney development should aid development of therapies for renal failure. MicroRNAs, which modulate gene expression through post-transcriptional repression of specific target mRNAs, contribute to the differentiation of stem cells,...

This study examined the potential biological hazard of pulp and paper waste solids. The solids examined were chosen on the basis of the range of wood-related organic extractives and were either primary solids screened from the effluent stream before secondary treatment, or biosolids from aerated sta...

This chapter covers the host range and specificity, morphology, life cycle, physiopathology, parasite-host interactions, role as disease vector and control and prevention (biological control, environmental approach, drug therapy, vaccination and insecticides) of Lepeophtheirus salmonis and Caligus r...
