Phyllosoma Larvae

Despite the global significance of spiny lobsters, the biology of their planktonic larvae, especially their carnivorous diet, is very poorly understood. Unsuitable diets and feeding regimes are one of the major reasons for consistently high mortalities during larval culture. In an effort to begin to determine the nutritional requirements of phyllosoma larvae of the spiny lobster, Jasus edwardsii, the present study first characterised the proximate composition of 11 previously identified groups of their potential prey. This included gelatinous zooplankton (chaetognaths, ctenophores, tunicates, siphonophores, scyphozoans, heteropods and pteropods), crustacean zooplankton (amphipods, copepods and euphausiids) and fish larvae. The composition of the 54 samples of 30 species of zooplankton ranged over 79.2–98.1% moisture content, and 1.9–54.2% for protein, 0.4–11.2% for carbohydrate, 0.1–27.9% for lipid, and 3.9–76.4% for ash of dry weight. The results showed that, in the most, zooplankton species provide a reliable source of protein. Only a small number of zooplankton had high lipid yield, suggesting that a narrow range of zooplankton species high in lipid are likely to be targeted by late-stage phyllosomas. The results of the present study will be useful as a guide for the development of artificial diets to improve phyllosoma aquaculture.

Hospitals offer snacks and drinks for sale to patients, staff and visitors. As food choice is heavily influenced by the options on offer, the present study audited the availability and purchase of snacks and drinks available in all NHS hospital sites across a large UK city. Data on the type and nutritional composition of all single-serve snacks (n=407) and drinks (n=238) available for sale in 76 hospital-based food retail units were collected. Purchasing data were obtained for products sold from a subset of food retail units over 4 weeks (6 units; 68,274 product sales). Single-serve snacks and drinks varied markedly in calorie content (snacks 18-641kcals; drinks 0-270kcals), fat content (snacks 0-39g; drinks 0-9g), sugar content (snacks 0.1g-76g; drinks 0-56g) and salt content (snacks 0.2g-2.9g; drinks 0-1.1g). Baked goods were the least healthy snack option (mean content: 383 kcals, 17g fat, 29g sugar and 0.4g salt). Most of the top selling products were crisps, confectionary, baked goods and hot drinks. Only 5/20 top selling snacks were healthy options. While healthy snacks and drinks are readily available in NHS sites, there is scope to reduce the availability of unhealthy options further and to support consumers to make healthier choices.
