    Fish-bone oil: Percent total body lipid and carbon-14 uptake following feeding of 1-14C-palmitic acid (1976)

    Notes: Abstract Bones contain the majority of body lipid in some marine fish. In the sheepshead wrasse Pimelometopon pulchrum and the sablefish Anoplopoma fimbria, the bone lipid comprised 79 to 93% and 52 to 82% of the total body lipid, respectively. The senorita Oxyjulus california, another species of wrasse, has only 14% of its body lipid in bone. To determine whether dietary lipid is deposited quickly in the bone lipid, three species of fish were fed 1-14C-palmitic acid. Radioactivity appeared in the bone lipid as soon as 12 h after feeding, with the species rich in bone lipid incorporating the highest activity relative to the flesh. Roughly 80% of the radioactivity recovered in A. fimbria bone lipid was found in triglyceride. Radioactivity was equally distributed between phospholipid and triglyceride in P. pulchrum bone lipids. The results suggest that in some marine fish the bones contain the majority of the organism's reserve energy.

    Notes: Abstract The cytochrome P-450 dependent mixed-function oxygenase (MFO) system ofNereis virens, found in the endoplasmic reticulum of the intestinal epithelium, has similar components and cofactor requirements when compared to other invertebrates. Worms exposed to food containing benzo(a)pyrene or a mixture of polychlorinated biphenyls (Aroclor 1254) had significantly higher MFO activity and cytochrome P-450 content than unexposed ones.N. virens from a site in Porland, Maine, USA, which was heavily contaminated with oil, and nearby “clean” reference sites were studied. The weight, MFO activity and presence or absence of gametes were determined. The MFO activity in worms from the oil-contaminated site was approximately six times that of worms from the reference sites; worms from the reference areas were six times larger than oil-contaminated worms. Worms from the oil-contaminated area lacked or had undeveloped gametes in spring, summer and fall. In contrast, many of the worms collected from the reference sites at the same times had fully developed gametes.

    Notes: Abstract. Concentrations of total mercury and methyl mercury were determined in sediment and fish collected from estuarine waters of Florida to understand their distribution and partitioning. Total mercury concentrations in sediments ranged from 1 to 219 ng/g dry wt. Methyl mercury accounted for, on average, 0.77% of total mercury in sediment. Methyl mercury concentrations were not correlated with total mercury or organic carbon content in sediments. The concentrations of total mercury in fish muscle were between 0.03 and 2.22 (mean: 0.31) μg/g, wet wt, with methyl mercury contributing 83% of total mercury. Methyl mercury concentrations in fish muscle were directly proportional to total mercury concentrations. The relationship of total and methyl mercury concentrations in fish to those of sediments from corresponding locations was fish-species dependent, in addition to several abiotic factors. Among fish species analyzed, hardhead catfish, gafftopsail catfish, and sand seatrout contained the highest concentrations of mercury. Filtered water samples from canals and creeks that discharge into the Florida Bay showed mercury concentrations of 3–7.4 ng/L, with methyl mercury accounting for 〈0.03–52% of the total mercury. Consumption of fish containing 0.31 μg mercury/g wet wt, the mean concentration found in this study, at rates greater than 70 g/day, was estimated to be hazardous to human health.

    Damage to grass shrimp (Palaemonetes pugio) embryo DNA by summer sunlight followed by DNA repair in the dark (2000)

    Notes: Abstract  DNA strand damage, using the single-cell gel electrophoresis (comet) method, was determined in different-stage embryos of grass shrimp (Palaemonetes pugio) collected from surface waters of a local estuary near Savannah, Georgia, USA. Late-stage embryos collected from the estuarine river at midday in the summer or placed in a solar simulator showed extensive DNA strand damage. The solar simulator, which produced the total irradiance found at midday in the summer at 34°N caused DNA strand damage in embryos similar to that found in sunlight-exposed embryos. A large increase in cyclobutane pyrimidine dimers (18 cyclobutane pyrimidine dimers per 1000 kilobases) were detected in DNA from the late-stage embryos exposed to the solar simulator for 1 h (solar irradiance of 126 μW cm−2). DNA repair took place within a few hours when late-stage embryos collected at midday from the river were transferred to the dark. Early grass-shrimp embryo stages showed no DNA strand damage either after placement in the solar simulator or when collected at midday in the summer. This lack of solar-damaged DNA in early-stage embryos was probably due to the presence of high concentrations of carotenoids, which can act as anti-oxidants to prevent damage from activated oxygen species produced by cells exposed to ultraviolet light. These carotenoids are utilized by the developing embryos, and only low concentrations of carotenoids were present in late embryo stages.

    Uptake, metabolism and discharge of polycyclic aromatic hydrocarbons by marine fish (1972)

    ISSN: 1432-1793

    Topics: Biology
    Notes: Abstract The uptake, metabolism and discharge of two polycyclic aromatic hydrocarbons, 14C-naphthalene and 3H-3,4-benzopyrene, were studied in 3 species of marine fish (mudsucker or sand goby, Gillichthys mirabilis; sculpin, Oligocottus maculosus; sand dab, Citharichthys stigmaeus). The path of hydrocarbons through the fish included entrance through the gills, metabolism by the liver, transfer of hydrocarbons and their metabolites to the bile, and, finally, excretion. The gall bladder was a major storage site of labeled hydrocarbons and their metabolites. The major product of 2H-3,4-benzypyrene metabolism was tentatively identified as 7,8-dihydro-7,8-dihydroxybenzopyrene. The 14C-naphthalene was metabolized to 1,2-dihydro-1,2-dihydroxynaphthalene after 24 h exposure. The urine appeared to the major avenne for discharge of labeled hydrocarbon from the body. Our laboratory results indicated that certain polycyelic aromatic hydrocarbons were rapidly taken up from seawater by the above fish, but detoxification mechanisms existed for efficient removal of these compounds from their body tissues.

    Lipid composition of the copepod Calanus hyperboreas from the Arctic Ocean. Changes with depth and season (1974)

    Notes: Abstract A build-up of reserve lipid, predominantly wax esters, occurred during the summer in the copepod Calanus hyperboreas, collected off an Arctic ice-island. This lipid storage was correlated with a phytoplankton bloom and was followed by a progressive decrease of lipid from 2.1 mg per individual in September to 0.4 mg in June. There was a rapid decrease in lipid utilization between October and December, followed by much slower decreases until June. Lowered respiration rates or the availability of different types or quantities of food in the winter and spring are possible explantions for the slower rate of lipid use. Laboratory starvation experiments for up to 90 days correlated with results from the field. Gas-liquid chromatographic studies of the lipids showed that both the alcohols and fatty acids of the wax esters were highly variable with season and depth, whereas the phospholipid fatty acids were not affected by changes in these parameters. Only summer samples bad wax esters with a phytoplankton-like fatty acid composition, and upper water winter copepods had wax esters with little polyunsaturation. The deep-water winter copepods had a very different wax-ester composition from the upper water samples, with a predominance of hexadecanol (all other copepod samples had 20:1 and 22:11 as the principal alcohols) and a high content of polyunsaturated acids. Deep-water C. hyperboreas may differ in food habits and life history from those in the upper water community.
