Sumber daya udang laut-dalam merupakan sumber daya masa depan yangpenting bagi pembangunan perikanan di Indonesia. Komposisi jenis sumberdaya udang laut dalam ini didapatkan lebih dari 38 jenis dengan jenis yangmendominansi udang Penaeid (Plesiopenaeus edwardsianus). Polapertumbuhannya adalah allometris dengan penyebaran terpusat padakedalaman 200-500 m. Potensi penangkapan udang laut-dalam di perairankawasan barat Indonesia sekitar 640 ton/tahun dengan upaya optimum 285 unit bubu dan di kawasan timur Indonesia sekitar 2.840 ton/tahun dengan upaya optimum 1.250 unit bubu. Rekomendasi pola pemanfaatan udang laut dalam yang berkelanjutan adalah dengan menerapkan opsi pengelolaan berupa penutupan daerah dan musim penangkapan, pembatasan upaya, dan penerapan kuota.Deep-sea shrimp resources is the future important resources for fisheries development in Indonesia. The catch composition of deep-sea shrimp found more than 38 species and the dominant species is Plesiopenaeus edwardsianus. The growth pattern is allometric with distribution in depth of 200-500 m. Potential yield of deep-sea shrimp in Indonesian western area is 640 ton/year with optimum effort about 285 unit of trap and in Indonesian eastern area is 2,840 ton/year with optimum effort about 1,250 unit of trap. The sustainable exploitation pattern of deep-sea shrimp is recommended to application of management options close area and fishing season, effort limitation, and quota application.

Fouladi Sabet A, Paighambari SY, Pouladi M, Raeisi H, Abbaspour Naderi R. 2018. Bycatch composition of cutlassfish trawlers during fishing season in Bushehr and Hormozgan, Persian Gulf, Iran. Biodiversitas 19: 2275-2282. This investigation was conducted to determine the bycatch composition of cutlassfish (Trichiurus lepturus) trawlers in Bushehr and Hormozgan waters during fishing season 2013. Data collection was carried out in the summer for Bushehr and in the autumn for Hormozgan province for one month. All trawler vessels were equipped with a 36 m head rope and 75 mm stretched mesh size in the codend and 90 to 200 mm stretched mesh size in the panel. 47 species included 35 species of teleosts, 9 species of elasmobranches and 3 species of invertebrates were identified in Bushehr. Also, 48 species included 38 species of teleosts, 7 species of elasmobranches and 3 species of invertebrates were identified in Hormozgan. The weight and numerical averages of bycatch species were 25.41 (kg h-1) and 205.9 (n h-1) in Bushehr, and 92.58 (kg h-1) and 440.4 (n h-1) in Hormozagan. I. megaloptera, S. tumbil, N. japonicus, D. acuta, C. sexfasciatus, L. equulus in Bushehr and P. sextarius, I. megalopteran, M. cinereus, P. macrophthalmus, N. japonicus and S. tumbil in Hormozgan had highest catch weight. Based on the weight and number, PCA and nMDS methods were indicative of two different assemblages in hunting places. Furthermore, ANOSIM similarity analysis confirmed the results of PCA and nMDS and showed a significant difference in the catch composition of two fishing zones.

WITH A note of sadness, the Committee on Nutrition of the American Academy of Pediatrics wishes to call to the attention of the membership the death of Robert Ramapatnam Williams. A noted chemist and scientist, Dr. Williams obtained world renown for his work on the isolation, identification, and synthesis of vitamin B1. He died at his home in Summit, New Jersey, in October 1965. Born in Nellore, India, February 16, 1886, of American missionary parents, he began teaching in the Philippines in 1908 and considered the Islands his second home. Williams never found time to earn a doctorate, although he attended Ottawa University (Kansas) and the University of Chicago for undergraduate and postgraduate work. He earned a B.S. in 1907 and an M.S. in 1908 and received honorary LL.D. and D.Sc. degrees from numerous universities. The story of his work with beriberi is one of the most exciting in the field of nutrition. While working in the Philippines in 1910 with the Chemical Division of the Bureau of Science, he became interested in the disease. He assisted in treating an infant dying of beriberi with brown-rice bran syrup. The child's dramatic recovery stirred the synthesis of thiamine chloride. His work culminated in extensive field trials, again in the Philippines, shortly after World War I. For this study, the Bataan peninsula was divided into two parts. In the western area the inhabitants ate plain white rice; those in the eastern area received plain white rice enriched with rice coated with vitamin B1, concentrate. Within weeks the death rate from beriberi dropped dramatically in the eastern area. It remained high in the western area until smugglers began "running in" the treated rice.

The Impact

Abstract Herring caught in the Thames Estuary sustain a small local commercial fishery (peak catch of 606 t during the 1972–1973 fishing season). Loss of local consumers' interest in the herring product has resulted in a gradual decline in catches and fishing effort for the stock. The stock is assessed using an age-structured model that relies on the information provided by a scientific trawl survey, and management advice is provided before the fishing season starts in October. Given its current low economic value, managers have requested evaluation of options for multi-annual Total Allowable Catches (TACs) in an attempt to reduce the frequency (and costs) of assessment and associated management advice. A tentative relationship between sea surface temperature and recruitment is used to predict the impact of increasing sea temperatures on future recruitment in the context of global warming. Hypotheses of auto-correlation and of an environmental effect on recruitment, together with trends in weight-at-age and the overestimation of spawning-stock biomass, form the basis for sensitivity tests of the management options considered. Implementation of a 3-year fixed TAC with 40% constraint in TAC variability and a slight reduction in target F would seem appropriate for the stock, given that it is within safe biological limits and compares well in terms of yield and risk with the current approach of annual TAC revision.

The Government

In this paper, we explore whether fiscal input brings the raise of regional education quality. To discuss this relationship, we employ Chinese provincial panel data ranged from 2008-2016. By constructing a two-way fixed effect model, we find that provincial education quality is positively associated with the fiscal expenditure, and more specifically, educational expenditure. This correlation is robust even we consider other important factors such economy growth, industrial structure and population structure. Besides, since the regional heterogeneity across China, the relationship between fiscal spending, and education quality may exhibit different patterns, we thus split our samples into eastern region and non-eastern region. Empirical results indicate that our main argument only exists in non-eastern area, which refers to the western area, where expanding fiscal expenditure would be more efficient for the government to raise provincial education quality. Meanwhile, fiscal policy would be less efficient to raise education quality for eastern area, thus new policy instrument is necessary.
