“…Korean researchers showed the anti‐diabetic effect of powdered sea urchin shells on type 2 diabetic rats . Minerals from the shells can be used for replacing and reconstruction of damaged or defective hard tissue; polysaccharides from the shells possess an anti‐inflammatory effect; and proteins from the shells and spines demonstrate antitumour activity . Secondary metabolites specific to sea urchins – polyhydroxynaphthoquinones (PHNQs) – also exhibit a wide range of pharmacological activities.…”

Using high-performance liquid chromatography with diode-array detection and mass spectrometry (HPLC-DAD/MS) we investigated the composition of polyhydroxynaphthoquinone (PHNQ) pigments from sea urchins Strongylocentrotus pallidus, St. polyacanthus, St. droebachiensis, Brisaster latifrons and Echinarachnius parma, collected in the Sea of Okhotsk and the Bering Sea. Identification of PHNQ pigments from sea urchins St. polyacanthus, B. latifrons, and E. parma was performed for the first time. Among the usual PHNQ pigments, mono- and dimethoxy derivatives of spinochrome E, not previously found in other sea urchins, were discovered in St. polyacanthus and St. droebachiensis. In St. droebachiensis, two monomethoxy derivatives of echinochrome A were detected, isolated previously from only tropical sea urchins. It was found that the composition and total content of pigments of St. droebachiensis depends on the collection area of the sea urchins and its depth and varies from 88 to 331 μg/g of dry shells. Sea urchins St. pallidus, B. latifrons and E. parma had average values for PHNQ pigment content, approximately 30 μg/g, and St. polyacanthus had a low PHNQ content, 13 μg/g.

This review analyses how mussel farming can contribute to the challenge of feeding the current and future world population in a more efficient and sustainable way. The analysis lays a foundation of the main issues with current practices of animal protein production, and compares them with the alternative of a massive expansion of mussel farming as a means to produce high‐quality protein for human and animal nutrition. The review also covers the ecological goods and services that mussels provide to the ocean and to the atmosphere, the health of mussel products, and the many potential uses of by‐products from the mussel industry in agriculture, in wastewater treatment, and in the feed industry.

“…Calcium (Ca) is an important mineral needed to not only trigger the molting process in shrimps but also create a new exoskeleton, and thus Ca is a vital nutrient requirement (Hou et al. ). Since over 80% of shellfish waste products are shells, and a large percentage of these shells are calcium carbonate, mollusk shells are by‐products that can be used as a good source of Ca in food production (Muir et al.…”

Effects of Different Levels of Marine Snail Shells in the Diets of Juvenile Kuruma Shrimps Marsupenaeus japonicus as a Source of Calcium

et al. 2018

View full text Add to dashboard Cite

Shells derived from marine mollusks represent over 80% of shellfish waste. Therefore, a 42‐d feeding trial was conducted to assess the effects of different levels of snail shells (SS) in the diets of kuruma shrimps Marsupenaeus japonicus as a source of calcium (Ca). An evaluation of the ability of SS to replace Ca was done by applying principles from a previously researched condition index to quantify the external characteristics of juvenile kuruma shrimps (initial body weight, 0.12 ± 0.01 g each [mean ± SD]) with relation to their growth performance. Five diets were formulated to include increasing levels of SS at 0, 2, 5, 10, and 0% (D1, D2, D3, D4, and D5, respectively); D1 was the positive control with Ca and no SS, and D5 was the negative control with no SS and no Ca included in the diet. Each diet was randomly allocated to triplicate groups of 15 shrimps per tank in a flow‐through system. Survival, body weight gain, specific growth rate, feed efficiency ratio, individual dry weight, total body length, condition index, freshwater stress resistance, and fatty acid composition were evaluated. Results indicated that shrimps fed 2% and 10% SS had significantly higher stress resistance than those fed the other diets (P < 0.05). Generally, dietary SS supplementation improved growth performances (such as final body weight, percent weight gain, specific growth rate, feed efficiency ratio), and the significantly highest performance was found in shrimps fed 10% SS (D4). Shrimps fed diets with ≤2% SS supplementation (D1, D2, and D5) had significantly lower condition index and hepatosomatic index. Under the present experimental conditions, using the condition index as a tool to evaluate the fitness of kuruma shrimps was beneficial; however, it was a poor indication of freshwater stress resistance. Instead, the ratio of n‐3:n‐6 in the shrimps’ bodies seemed to be correlated with stress resistance. Additionally, supplementing 10% SS in kuruma shrimp diets is recommended for better growth performance.
