“…In this way it can be determined that over half the PUFA settling from surface waters reached the benthos. The maximum net PUFA accumulation for populations of Acanthostepheia malmgrenii and Mysis mixta (Richoux 2004) accounts for ~2 and 4% respectively of the 0.345 g m -2 in the 220 m traps. The higher value for M. mixta suggests that this mysid population was better able to sequester settling PUFA.…”

) occurred 16 d later. The lipid and PUFA supply to the benthos was over 10 times that accumulated by important amphipod and mysid populations in Conception Bay. In the deep traps, PUFA were maintained at high levels (33 to 35%) throughout the bloom period while bacterial markers were at their lowest (2.3 to 2.9%). A comparison of fluxes showed that over half the PUFA survived transit from 80 to 220 m during the bloom period. These data indicate a rapid transfer of highly nutritious material to the benthos during the spring bloom in Conception Bay.

“…The Canadian province of Newfoundland and Labrador is located in a cold-temperate region of the Northwest Atlantic, where species with subarctic/Arctic affinities are common. While several studies have been carried out in coastal and other shallow-water ecosystems of the region [ 11 – 13 , 34 – 39 ], information on the lipid content and composition of the deep-sea counterparts remains fragmentary. Data only exist for total lipid contents and classes (50–1500 m) [ 19 ], as well as FA composition in corals (770–1370 m) [ 40 ]; and lipid contents, classes, and FA signatures in deep-sea gastropods and their epibiotic sea anemones (191–627 m) [ 41 ].…”

Lipids are key compounds in marine ecosystems being involved in organism growth, reproduction, and survival. Despite their biological significance and ease of measurement, the use of lipids in deep-sea studies is limited, as is our understanding of energy and nutrient flows in the deep ocean. Here, a comprehensive analysis of total lipid content, and lipid class and fatty acid composition, was used to explore functional diversity and nutritional content within a deep-sea faunal assemblage comprising 139 species from 8 phyla, including the Chordata, Arthropoda, and Cnidaria. A wide range of total lipid content and lipid class composition suggested a diversified set of energy allocation strategies across taxa. Overall, phospholipid was the dominant lipid class. While triacylglycerol was present in most taxa as the main form of energy storage, a few crustaceans, fish, jellyfishes, and corals had higher levels of wax esters/steryl esters instead. Type and amount of energy reserves may reflect dietary sources and environmental conditions for certain deep-sea taxa. Conversely, the composition of fatty acids was less diverse than that of lipid class composition, and large proportions of unsaturated fatty acids were detected, consistent with the growing literature on cold-water species. In addition, levels of unsaturation increased with depth, likely suggesting an adaptive strategy to maintain normal membrane structure and function in species found in deeper waters. Although proportions of n-3 fatty acids were high across all phyla, representatives of the Chordata and Arthropoda were the main reservoirs of these essential nutrients, thus suggesting health benefits to their consumers.

Spiny lobsters are one of the most valuable seafood products in the world. A major bottleneck to the development of commercial spiny lobster aquaculture is a lack of understanding of the natural diet and nutritional requirements of the larvae. Recent studies have identified the varied pelagic zooplankton prey of spiny lobster phyllosoma, which includes gelatinous taxa, such as ctenophores, jellyfish, salps, chaetognaths, polychaetes, siphonophores and radiolarians, as well as crustaceans, such as amphipods, copepods and krill. In light of these studies, the extensive range of published studies on the biochemical composition of zooplankton have been reviewed in an attempt to provide an initial indication of the possible nutritional requirements of spiny lobster phyllosoma, including protein, lipid, carbohydrate, ash and moisture content. The results indicate that protein is the predominant component in all taxonomic groups of potential prey, which is 46.7 AE 6.0% of dry mass (mean AE SE) in crustaceans and 18.3 AE 7.8% of dry mass in gelatinous zooplankton, followed by lipid, which is 23.8 AE 4.5% of dry mass in crustaceans and 5.3 AE 1.4% of dry mass in gelatinous zooplankton. Carbohydrate is 1.9 AE 0.1% of dry mass in crustaceans and 0.9 AE 0.1% of dry mass in gelatinous zooplankton. Despite the much lower nutrient and energy content of gelatinous zooplankton compared with crustaceans, feeding by phyllosoma on gelatinous zooplankton may provide them more readily accessible nutrients. The results indicate that spiny lobster phyllosoma have a high dietary requirement for protein.
