Effects of temperature and ammonium on growth, pigment production and nitrogen uptake by four species of Porphyra (Bangiales, Rhodophyta) native to the New England coast

Abstract: Porphyra is one of the world's most valued maricultured seaweeds and has been cultivated for several hundred years in Asia. The objective of this study was to produce critical information as a guide for the selection of an appropriate Porphyra species from coastal New England for the development of a land-based aquaculture system. Four Northwest Atlantic Porphyra species: P. leucosticta, P. amplissima, P. linearis and P. umbilicalis, were cultivated for 1 and 2 weeks at saturated light intensities (100-150 μmo… Show more

“…Further to this, Morgan and Simpson (1981b) utilized apical plant sections, likely contributing to improved nutrient uptake, whereas the current study made use of whole thalli. Younger tissues typically have higher rates of nutrient uptake, due to faster growth and greater proportion of cells in direct contact with the medium than older plant segments (Hafting 1999, Kim et al 2007. These values for growth rates in experimental conditions compare favourably for those found in nature of 4% d -1 in actual commercial harvests on Digby Neck, Nova Scotia (Lukeman et al 2012).…”

“…Total tissue N and C were determined for each biomass survey. N removal was calculated using the following equation after Kim et al (2007) . Growth rate then declined to 0% d -1 in early July when temperature reached 13.5°C and remained at or below zero growth until the end of the experiment in October.…”

“…This result suggests that a land based IMTA system could be a good way to resolve the pH problem. Fish effluent also provide sufficient nutrients for the growth of seaweed (Neori et al 2000, Martínez-Aragón et al 2002, Matos et al 2006, Kim et al 2007, Corey et al 2013. The use of fish effluent for seaweed cultivation requires that particulate matter be filtered before entering the seaweed tanks.…”

“…Foliose Bangiales species (nori or laver) have long been the focus of intense investigations both from a biological and molecular perspective (Drew 1949;Krishnamurthy 1969;Conway and Cole 1977;Cole and Conway 1980;SidirelliWolff 1992;Orfanidis 2001;Klein et al 2003;Broom et al 2004;Bray et al 2006;Kim et al 2007;Brodie et al 2008;Sutherland et al 2011;Mols-Mortensen et al 2012). The genus Pyropia is not only the most speciose of the foliose Bangiales genera, but also contains the widest geographical distribution and largest morphological variation among its members (Sutherland et al 2011).…”
