Sea cucumber aquaculture has flourished as a result of increasing demand coupled with declining wild fisheries and has been facilitated by technical progress in the production and grow-out phase of larvae and small juvenile sea cucumbers. China has developed a large and successful sea cucumber aquaculture industry based on the temperate species Apostichopus japonicus (Selenka, 1867). China consumes most of its domestic sea cucumber production (193, 705 tons: 2013), exporting only a few dozen tons. Much of the success of sea cucumber aquaculture in China came from advances in culture methods, especially for the early stages of broodstock conditioning, larval production and settlement, and the critical early juvenile development stage. These artificial approaches to production are a precondition for all aquaculture models, and the scientific procedures and management protocols must be strictly adhered to for success. Similarly, the growout phase of sea cucumber production in China has evolved from attempts using disused fish and shrimp ponds to new, dedicated ponds developed to meet the more sensitive requirements of sea cucumbers for water quality and substrate type and to the use of ocean ranching. Various diseases have affected this industry and become barriers to its sustainable development. To achieve higher survival rates and better production quality, the trend has been toward ocean ranching of sea cucumbers and stock enhancement, and production levels have increased significantly in recent years. While cost-effective methods for sea cucumber aquaculture close to their point of consumption is good news for wild stocks of sea cucumbers in different parts of the world, there is a potential downside in the environmental impact of such extensive production methods. The influence of sea cucumber aquaculture on the environment and the influence of the environment on sea cucumber aquaculture are important issues relating to ecological security and sustainability.

Lymphangioma is an uncommon benign tumor that develops in the lymphatic system. Abdominal lymphangiomatosis is extremely rare in adult patients, and the clinical symptoms of this condition are complicated and atypical. We report a case of abdominal lymphangiomatosis in a 38-year-old female who presented with intestinal bleeding and protein-losing enteropathy, as well as lesions in the lung and bones. A computed tomography scan revealed multiple small cystic lesions without enhancement. Histological examination revealed microscopic cysts were submucosal, with walls composed of thin fibrous tissue, and D2-40 stained highlight the lining of the lymphatic channels by immunohistochemical method. We make a comparison with the cases reported before, and also discuss the diagnose of diffuse pulmonary lymphangiomatosis and Gorham's disease.

This study investigated the growth performance and nutritional composition of scale artificially cultured cuttlefish Sepia pharaonis. Juveniles were cultured in an open-culturing cement pool system for 120 days. The body weight increased from 10.21 AE 1.44 g to 570.71 AE 126.32 g from 50 days old to 170 days old, and the average growth rate was 4.67%. The proximate, amino acid and fatty acid compositions of S. pharaonis muscles were analysed every 40 days to compare the quality. The cultured S. pharaonis were rich in essential amino acids (EAAs), functional amino acids (FAAs), docosahexaenoic acid (DHA) and polyunsaturated fatty acids (PUFAs), which accounted for 32%, 46%, 28% and 54% (dry weight) respectively.Total amino acids (TAAs) and EAAs exhibited a clear distinction between ages, and significant differences were observed among the levels of individual amino acids, including Pro, Ala, Asp and Lys, which were significantly higher at 130-170 days old than at 50 days old (p < 0.05). Although the total saturated fatty acids, monounsaturated fatty acids and PUFAs were statistically similar between ages, C17:0, C22:6 n-3 and PUFAs were higher at 130-170 days old than at 50 days old (p < 0.05). The results indicate that large-scale artificial culture of S. pharaonis can be achieved under the conditions of a cement pool. This study also provides new information regarding the growth performance and nutritional composition of cultured S. pharaonis, which will contribute to the development of aquaculture practices for this species.
