    Notes: Diatom populations and silica concentrations were monitored at frequent intervals in the shallow, eutrophic Loch Leven over a 27-day period (October 1972) and the influences of the inflows, outflow and the sediment were assessed. Changes in dissolved and particulate silica are accounted for by incorporating the results into a silica budget.During this period processes affecting silica within the loch were more important than those outside. The incorporation of diatom frustules into the sediments and the release of dissolved silica from the sediments appeared to be of particular importance. Evidence suggests that dissolution of the frustules of some planktonic diatom species was also important.

    Notes: The species composition of planktonic diatom crops in Loch Leven, Kinross, Scotland varied considerably over the years studied (1968–71) with centric forms predominating. Dense populations were often produced and rates of increase and decrease were high.Relations with dissolved silica did not appear always to be simple; instances occurred during which both diatoms and silica were increasing or decreasing. Moreover, certain rates of increase in dissolved and frustule silica exceeded the rates at which silica flows into the loch even when the inflows appeared to be the only available dissolved silica source.

    Notes: SUMMARY. The crustacean Zooplankton community in Bough Beech, a flooded valley reservoir in south-east England, was investigated in the early years of impoundment. The nutrient status and phytoplankton were typical of a lowland eutrophic lake, and this was reflected in the composition of the Zooplankton. At any given time, the latter comprised one or two cladoceran and two or three copepod species, of which the cladocerans were generally numerically predominant. Marked alterations in the Zooplankton community occurred in the first 2 years of the study and were related to changes in predation pressure by fishes. By the end of the third year, the composition of the Zooplankton community had stabilized.The cladoceran biomass was normally in excess of that of the copepods, with maxima in spring and autumn. Peaks in copepod biomass occurred within 2 months of those of the Cladocera.

    Notes: SUMMARY. The River Eden (Kent, England) holds a mixed coarse fish population in which minnows (Phoxinus phoxinus), gudgeon (Gobio gobio), chub (Leuciscus cephalus) and dace (Leuciscus leuciscus) are numerically predominant. Chub and dace provide the major interest to anglers and their growth and production were studied. Observed growth rates of both species were marginally below recorded averages from other British habitats. Back-calculations showed that year-class strength and relative growth rates varied between years. Instantaneous mortality rate Z was 0.147 for chub aged 1–10, 0.438 for chub aged 10 and over, and 0.172 for dace. Exclusive of the 0-group, fish numbers, biomass (wet wt) and production were found to be 0.1305 m-2, 19.12 gm-2 and 5.38 gm-2 year-1, respectively, for chub and 0.0968 m-2, 4.33 gm-2 and 1.69 gm-2 year-1 for dace. Smoothing of data produced theoretical production figures of 6.69 gm-2 year-1 for chub and 1.15 gm-2 year-1 for dace.

    Notes: Samples of southern peas [Vigna unguiculata (L.) Walp., cv. Purple Hull Pinkeye] were obtained at critical stages in a normal harvesting, transportation, and cryogenic processing operation and microbiologically analyzed for total plate count (TPC), Enterobacteriaceae count (ENT), and yeast and mold counts. Molds were identified to genera while ENT were identified to species. Operations involving extended holding times tended to increase all counts significantly, although subsequent processing reduced these counts to an acceptable level. Predominant genera of ENT and molds appeared to be soil borne organisms such as Enterobacter agglomerans, Enterobacter cloacae, Klebsella pneumoniae, and Serratia liquefaciens, and Fusarium, Cladisporium, Alternaria, Phoma, and Aspergillus, respectively.

    Notes: The diffusion of sodium chloride and acetic acid into herring muscle and their subsequent effects on the myotibrillar proteins were studied at different temperatures and fish:cure ratios. Acid was found to penetrate tissue more quickly than salt. The acid and salt cause an initial “hardening” of the tissue, the extent of which is proportional to the concentration of each, but it is considered that the resultant fall in pH activates muscle cathepsins. SDS PAGE indicated that proteolysis of the myosin heavy chains was concomitant with subsequent tissue softening. Electron microscopy detected little disintegration of myofilaments, but extensive break-up of Z-lines.

    Notes: Broiler chicken carcasses were inoculated with Salmonella typhimurium (180–360,000 cells per carcass), then, in a simulated commercial chilling process, were prechilled at 18°C in water containing glutaraldehyde. On broilers that had been prechilled for 30 min in 0.5% glutaraldehyde (pH 8.6), then chilled in slush ice for 20 min, salmonellae were eliminated when the inoculum level per carcass was 250 cells, but not when the level was 360,000 cells. Transfer of salmonellae from inoculated to uninoculated carcasses (cross contamination) was prevented by glutaraldehyde at 0.01% or more in the prechill water, when the inoculum level was 200–300 cells per carcass. It was not prevented when the level was 360.000 cells per carcass. A lo-min urechill in 0.5% alutaraldehvde (pH 8.6) extended- carcass shelf-life at 2°C about 6 days beyond that of controls.
