    Notes: The use of different methods of heat shocking for green mussels was evaluated. These methods were heat treatment at 60 and 100 °C either in a hot water bath, in water-saturated air or in dry heat. It was established that relaxation of the adductor muscles, which facilitates shucking, was quickest for the hot water bath treatment at both test temperatures. This treatment caused 100% of the mussels to be open at either 60 or 100 °C in 3–5 and 0.33–1 min exposure times respectively. The sensory acceptability of all the heat-shocked mussel meats ranged from dislike slightly to like slightly. Generally, the increase in pH and water activity of the heat-treated mussels, relative to the untreated mussels, was not statistically significant at the 5% level of significance.

    Notes: Toxin assays namely: the mouse bioassay, the receptor binding assay (RBA) and, the immuno-chromatography assay using MIST Alert™ rapid test kit were used to determine the concentrations of Paralytic Shellfish Poisoning (PSP) toxins from untreated and heat shocked Philippine green mussels, Perna viridis contaminated with Pyrodinium bahamense var. compressum. Toxin levels ranging from 4–15 μg STXeq/100 g sample were quantified in the mussel samples analyzed using RBA. Higher levels of PSP toxins at about 30 μg STX eq/100 g sample were recorded using mouse bioassay, which was attributed to interfering factors that could induce mouse death resulting in false positive reactions. The MIST Alert™ test kit showed positive reaction in the samples evaluated based on the reported average profile of PSP toxin analogues at about 40 μg STX eq/100 g sample. The test heat treatments did not elicit definitive change in the PSP toxin profiles of heat shocked mussels relative to the untreated samples.

    Notes: Chlorine-assisted chilled tumble washing of green mussel meats was done using 5 and 10ppm chlorine solutions maintained at 5 and 10C for 3 min. No significant difference (P 〈 0.05) was established in terms of meat yield, pH, Aw or sensory qualities for tumble washed samples. The mussel meats were given sensory acceptance ratings of up to “like slightly”. A 2% weight gain of mussel meats was established after washing. Heat shocking in tandem with tumble washing affected 1–3 unit log reduction in TPC and coliform counts and about a 4 log reduction in Vibrio spp. counts of mussel meats. The 2 protocols were presented as value-adding steps to improve mussel meat quality. Philippine micro- and small-scale shellfish processors and vendors were identified as potential users of the technology presented in the study.

    Notes: Abstract For the first time with Gracilariopsis bailinae Zhang et Xia, outplanting of laboratory-generated sporelings was undertaken. Young sporelings of the species were planted 1.0 and 2.0 m below the lowest tide level, using the monoline method (fixed to the bottom), off Amunitan, Gonzaga, Cagayan, northern Philippines from February to March 1996. After six weeks of culture at 1.0 m depth, sporelings from which the apices had been removed grew significantly faster than did intact sporelings or sporelings at 2.0 m depth. The maximum growth rate (9.7% d−1) was obtained for sporelings with cut apices grown at 1.0 m below the lowest tide level during the third week of culture period and the lowest (2.6% d−1) was attained for uncut sporelings cultured 2.0 m below the lowest tide level during the first week.

    Description: The proposed plan for enrichment of the Sulu Sea, Philippines, a region of rich marine biodiversity, with thousands of tonnes of urea in order to stimulate algal blooms and sequester carbon is flawed for multiple reasons. Urea is preferentially used as a nitrogen source by some cyanobacteria and dinoflagellates, many of which are neutrally or positively buoyant. Biological pumps to the deep sea are classically leaky, and the inefficient burial of new biomass makes the estimation of a net loss of carbon from the atmosphere questionable at best. The potential for growth of toxic dinoflagellates is also high, as many grow well on urea and some even increase their toxicity when grown on urea. Many toxic dinoflagellates form cysts which can settle to the sediment and germinate in subsequent years, forming new blooms even without further fertilization. If large-scale blooms do occur, it is likely that they will contribute to hypoxia in the bottom waters upon decomposition. Lastly, urea production requires fossil fuel usage, further limiting the potential for net carbon sequestration. The environmental and economic impacts are potentially great and need to be rigorously assessed.
    Description: This paper was developed under the Global Ecology and Oceanography of Harmful Algal Blooms (GEOHAB) core research project on HABs and Eutrophication and the GEOHAB regional focus on HABs in Asia. GEOHAB is supported by the International Oceanographic Commission (IOC) of UNESCO and by the Scientific Committee on Oceanic Research (SCOR), which are, in turn, supported by multiple agencies, including NSF and NOAA of the USA.
