An operational satellite remote sensing system for ocean fishery

Acta Oceanologica Sinica 2004年第3期23卷 427-436页

Ocean environmental information is very important to supporting the fishermen in fishing and satellite remote sensing technology can provide it in large scale and in near real-time. Ocean fishery locations are always far away beyond the coverage of the satellite data received by a land-based satellite receiving station. A nice idea is to install the satellite ground station on a fishing boat. When the boat moves to a fishery location, the station can receive the satellite data to cover the fishery areas. One satellite remote sensing system was once installed in a fishing boat and served fishing in the North Pacific fishery areas when the boat stayed there. The system can provide some oceanic environmental charts such as sea surface temperature (SST) and relevant derived products which are in most popular use in fishery industry. The accuracy of SST is the most important and affects the performance of the operational system, which is found to be dissatisfactory. Many factors affect the accuracy of SST and it is difficult to increase the accuracy by SST retrieval algorithms and clouds detection technology. A new technology of temperature error control is developed to detect the abnormity of satellite-measured SST. The performance of the technology is evaluated to change the temperature bias from -3.04 to 0.05 ℃ and the root mean square (RMS) from 5.71 to 1.75℃. It is suitable for employing in an operational satellite-measured SST system and improves the performance of the system in fishery applications. The system has been running for 3 a and proved to be very useful in fishing. It can help to locate the candidates of the fishery areas and monitor the typhoon which is very dangerous to the safety of fishing boats.

Based on data of demersal trawl Samples from 1987 to 1988 in the Zhujiang Estuary and its adjacent waters, relationships between fish community and environmental factors are studied by using clssification , MDS ordina-tion and several community parameters. The results shaw that the distribution of fish shoes is zoned by salinty anddivided into three types. The freshwater community which is restricted in the Lianhua Hill - Humen waterway is sim-ple and stable, the coastal community which lives in the shallow waters is complex, and the estuary community whichis idenhfied in the Lingdingyang area and affected by Physical and ecological pinemore greatly greatly has obvious seasonalvariations.

Study on low-temperature lipase of psychrophilic bacterium 2-5-10-1 isolated from deep sea of Southern Ocean

A strain of psychrophilic bacterium, 2-5-10-1, which produces low-temperature lipase, is isolated from the deep sea of Prydz Bay in Southern Ocean. The highest lipase secretion of this strain is observed at 5 degreesC and this temperature is also for optimal growth. Tween 80 and olive oil enhance secretion of lipase. The optimal temperature and pH for lipase activity are 35 degreesC and 7.5 degreesC respectively. At 0degreesC, the lipase still has 37% relative enzyme activity. The lipase shows high thermolability, more than 50% activity lost after incubation at 60 degreesC for 15 min. EDTA has no effect on lipase activity, indicating the lipase activity is independent of divalent cation. In contrast, the lipase activity is inhibited drastically by Cu2+ and Zn2+.

＜正＞The patterns of allozyme polymorphisms in various organs of Perinere-sis aibuhitensis were investigated. Population was collected from the East Sea coast of Wenling of Zhejiang Province, china. Fourteen isozymes in six tissues or organs;head, pharynx, esophagus, intestine, muscle and parapodium of Perineresis ai6u-hitensis were studied by using the vertical polyacrylamide gel electrophoresis, the phe-notypes and the expressions of the isozymes were analyzed. The results showed that CAT isozymes did not express in the head and D-GCDH isozymes did not express in the pharynx. The SOD isozyme existed in all these tissues. ADH, ATP, EST, FDH, GAD, GDH, LDH, MDH, ME, POD, SCD and SDH isozymes exhibited an apparent tissues-specificity.

Protochordate amphioxus is an emerging model organism for comparative immunology

Progress in Natural Science:Materials International 2009年第8期19卷 923-929页

作者： Shicui Zhang a, Yujun Liang a, Guangdong Ji a, Zhimeng Zhuang b a Department of Marine Biology, Ocean University of china, Qingdao 266003, china b Yellow Sea fishery Research institute, Chinese Academy of fishery Science, Qingdao 266071, china Department of Marine Biology Ocean University of China Qingdao 266003 China Yellow Sea fishery Research institute Chinese Academy of Fishery Science Qingdao 266071 China

Protochordate amphioxus is an extant invertebrate regarded quite recently as a basal chordate. It has a vertebrate-like body plan including a circulation system with an organization similar to that of vertebrates. However, amphioxus is less complex than vertebrates for having a genome uncomplicated by extensive genomic duplication, and lacking lymphoid organs and free circulating blood cells. Recent studies on immunity have demonstrated the presence in amphioxus of both the constituent elements of key molecules involved in adaptive immunity such as proto-major histocompatibility complex (proto-MHC), V region-containing chitin-binding protein (VCBP) and V and C domain-bearing protein (VCP), and the complement system operating via the alternative and lectin pathways resembling those seen in vertebrates. In addition, the acute phase response profile in amphioxus has been shown to be similar to that observed in vertebrates. These findings together with the relative structural and genomic simplicity make amphioxus an ideal organism for gaining insights into the origin and evolution of the vertebrate immune system, especially adaptive immunity, and the composition and mech- anisms of the vertebrate innate immunity.

STUDIES on the nutrition requirement of larval fish have made some progress abroad, but therehave been no reports on such studies in china. It was determined recently that n-3 HUFA (es-pecially 22: 6(n-3) (DHA) and 20:5 (n-3) (EPA)) is essential for larval seafish growth. Thehigh content of DHA in seafish eggs and the low content of DHA in rotifers show that rotifersas live food cannot satisfy the n-3 HUFA requirement of larval seafish. Some scientists ob-
