Abstract

To evaluate and improve the sustainability of Walleye Pollock fisheries for the Pacific stock according to the global standard, the fisheries is evaluated by MSC Fishery Standard which is a globally recognized requirements for an eco-label certification of sustainable fishery published by the Marine Stewardship Counsil. MSC Certification Requirements were used which describes the scoring of 31 performance indicators (PI) grouped to three principles, (1) stock assessment, (2) ecological consideration, and (3) fishery management. For the certification, all score should be over 60, and the average score for each principles should be over 80. The evaluation was carefully conducted by two researchers independently based on the disclosed information. As a result, the total average score was 78.3, and the average score for each principle was (1) 92.5, (2) 69.0, (3) 84.4. The scores of the 4 PIs in principle 2 were under 60. Thus, the fisheries of the Walleye Pollock Pacific stock does not meet the requirements as sustainable fishery as the current condition according to the MSC standards. The main cause for the low score is the lack of the monitoring of the otter trawl fishery on the damage to the sea bed, and on the by-catch. An observers program would improve the sustainability of the fisheries.

Abstract

NS(B 2Π–X 2Π) chemiluminescence has been observed from the thermal-energy reaction between N(2D) atoms and OCS molecules under single collision conditions. The vibrational populations of NS(B) decrease monotonically with increasing vibrational quantum numbers from v’=0 to 4, while the rotational temperature is constant at about 1000 K for all vibrational levels. The observed vibrational distribution is more excited than the statistically predicted ones, suggesting that the reaction proceeds by a direct mode. [ABSTRACT FROM AUTHOR]

Nakano, Toshihide, Ryuji Tominaga, Ichiro Nagano, Hayato Okabe, and Hisataka Yasui. Pulsatile flow enhances endothelium-derived nitric oxide release in the peripheral vasculature. Am J Physiol Heart Circ Physiol 278: H1098-H1104, 2000.--The effects of pulsatility in blood flow on endothelium-derived nitric oxide (EDNO) release in the peripheral vasculature were investigated. The basal and flow-stimulated EDNO release were compared between pulsatile and nonpulsatile systemic flows before and after the administration of NO synthase inhibitor [N.sup.G]-monomethyl-L-arginine (L-NMMA). Peripheral vascular resistance (PVR) was significantly lower in pulsatile flow than in nonpulsatile flow, but this difference disappeared after L-NMMA. The percent increase in PVR by L-NMMA was significantly larger in pulsatile flow. In reactive hyperemia in the hindlimb, the peak flow did not differ; however, both the repayment flow and the duration were significantly larger in pulsatile flow. Percent changes of these parameters by L-NMMA were significantly larger in pulsatile flow. These data indicated that pulsatility significantly enhances the basal and flow-stimulated EDNO release in the peripheral vasculature under in vivo conditions. We also studied the involvement of the [Ca.sup.2+]-dependent and [Ca.sup.2+]-independent pathways in flow-induced vasodilation using calmodulin inhibitor calmidazolium and tyrosine kinase inhibitor erbstatin A. PVR was significantly elevated by erbstatin A but not by calmidazolium, suggesting that flow-induced vasodilation was largely caused by tyrosine kinase inhibitor-sensitive activation of NO synthase. nitric oxide synthase; reactive hyperemia; calmodulin; tyrosine kinase; [N.sup.G]-monomethyl-L-arginine
