Biology of selected Clarias catfish species used in aquaculture
Get PDFCatfish are important organisms used extensively in aquaculture. For this review, we are focusing on specific species of catfish in the genus Clarias, primarily Clarias batrachus, C. gariepinus and C. macrocephalus, because of their widespread use in aquaculture and the considerable amount of information that has been amassed on different aspects of their biology. This review summarizes information available on topics ranging from the taxonomy and geographic distribution of these catfish to work done on them at the genetic, molecular biological and genomic levels. This information may be useful in future efforts to grow and expand their use in aquaculture
Marquesan legends (manuscript)
Get PDFThis manuscript is found in the Samuel H. Elbert papers, held in the Pacific Collection at the University of Hawaiʻi at Mānoa. The finding aid to the papers is here: https://archivesspace.library.manoa.hawaii.edu/repositories/4/resources/361. It is written in English and Northern and Southern Marquesan languages, although most of the stories from the north are provided in English. This manuscript was likely written in the late 1930's.From Elbertʻs introduction: "This material was collected from the islands of Tahuata, Hivaʻoa, Nukuhiva and Ua Pou in the Marquesas group from March 1934 to May 1935. Sometimes the legends and chants were copies from old notebooks written down by the Marquesans themselves, but more often they were told to me directly by old men or women.
Current situation analysis and development suggestions of the Apostichopus japonicus culture industry in Shandong Province
Get PDFIn the 1980s, Shandong Province took the lead in establishing breakthrough industrialized seedling raising and breeding technologies for Apostichopus japonicus and successfully led the ‘fifth wave of mariculture’ in China. In 2008, the experiment of ‘raising sea cucumber from north to south’ proved successful, and sea cucumber culture gradually radiated and extended to Fujian, Jiangsu, Guangdong, and Zhejiang Provinces in southern China. The total output of sea cucumber culture in Shandong Province accounts for more than 70% of the market in China, and the sea cucumber industry is now a pillar of the fishery economy in Shandong Province. This paper systematically introduces the development status of the sea cucumber breeding industry in Shandong Province in recent 10 years, summarizes the current problems and challenges, and puts forwards development suggestions; this guidance has significance for the healthy and sustainable development of the sea cucumber breeding industry in both Shandong Province and the whole country
Diet high in α-linolenic acid up-regulates fatty acids biosynthesis-relate gene expression in the hepatopancreas of Yellow River carp (Cyprinus carpio)
Get PDFLittle information on the effects of a high α-linolenic acid (C18:3n-3) diet on fatty acid composition and lipid-producing gene expression in the hepatopancreas from Yellow River carp (Cyprinus carpio). In the study, 60 common carp juveniles were fed for 50 days, a high α-linolenic acid diet supplemented with linseed oil (LO), and a control diet without the addition of linseed oil to evaluate the effect on lipid composition and gene expression of peroxisome proliferator-activated receptors (PPAR-α), delta-6 fatty acid desaturase (delta-6-Fad), stearoyl-CoA-desaturase (SCD), and fatty acid desaturase-5 (Elovl5) in the hepatopancreas. The results showed that increased levels of C20:4n-6, C18:3n-3, C20:5n-3, and C22:5n-3 were observed in LO treated Yellow River carp hepatopancreas. PPAR-α, delta-6-Fad and Elovl5 gene expression was up-regulated in the Yellow River carp's hepatopancreas fed with a high α-linolenic acid diet (P < 0.05), while SCD gene was down-regulated. In conclusion, the addition of α-linolenic acid to the Yellow River carp diet affected gene expression (SCD, PPAR, delta-6-Fad, and Elov15) involved in regulating fatty acid (FA) profile Yellow River carp. It is suggested that delta-6-Fad, Elovl5, and PPAR-α be essential messengers responsible for translating nutritional stimuli into gene expression changes in the hepatopancreas
