A survey was conducted during November, 2012 to May, 2013 to assess the status of major post harvest diseases of papaya fruits in the local markets of Mymensingh. Average percentage of diseased fruits at the markets were 29.83 and diseased fruits ranged from 20.40% to 38.04% during the study period. Highest percentage of diseased fruits (38.04%) was recorded in the month of May, 2013 followed by March, 2013 (37.98%). The minimum percentage of diseased fruits (20.40%) was recorded in January, 2013 followed by December (22.68%). Total six post-harvest diseases was recorded, viz. Anthracnose, Fusarium rot, Stem end rot, Rhizopus rot, Aspergillus rot and Penicillium rot. Anthracnose showed highest mean incidence (14.17 %) followed by Fusarium rot (7.26%) where as Pencillium rot showed lowest mean incidence (0.70%). In the market, anthracnose showed maximum percentage of mean disease abundance (46.11%) followed by Fusarium rot (24.61%). The findings of this study revealed that total six post-harvest diseases are associated with ripe papaya in different markets of Mymensingh. Moreover, May is the predominant month of highest incidence and abundance of all diseases. DOI: http://dx.doi.org/10.3329/jbau.v12i1.21235 J. Bangladesh Agril. Univ. 12(1): 25-28, June 2014

The fourth annual meeting of the International Commission for Northwest Atlantic Fisheries was held in Halifax, Canada, from June 14 to 18, 1954, under the chairmanship of Dr. Stewart Bates (Canada). The Commission received and approved a report from the Standing Committee on Research and Statistics recommending modifications and additions in the Commission's system of collecting and compiling statistics. With regard to haddock regulations, the Committee had referred to one of its panels the question of a proposed amendment to the regulation exempting a specified maximum percentage of the catch of haddock to ensure that there was no hardship to fishermen. Upon the recommendation of the scientific advisers that there was no undue hardship, the Commission noted that important principles of exemption were involved, and furthur serious consideration was required. The Commission received and approved reports which dealt with the status of the fisheries, its research programs in relation to the more comprehensive research program adopted by the Commissionn i 1953, and commercial fishing regulations. The Commission chose Ottawa, Canada, as the site of its next meeting which was to be held in June 1955.

Abstract This book chapter outlines the future steps in improving the status of the tropical tuber crops: (1) reduce the period of maturity of all the TTCs to 110-150 days, (2) improve the tuber shape and make them more definitive in shape, (3) improve plant architecture to attain a harvest index of 0.70, (4) eliminate antinutritional factors and improve nutritive values, (5) impart resistance to the three major biotic problems afflicting the TTCs: CMD (cassava mosaic disease), taro leaf blight and sweet potato weevil, (6) introduce determinacy in cassava and yams, (7) increase the post-harvest storage life, (8) reduce the loss during post-harvest storage, transportation and processing, (9) use biotechnological means to alter starch characteristics like amylose content, chain length and phosphorus content in starch, (10) it is also suggested that there should be a 'starch bank', which acts as a repository of different starches and provides information on all physicochemical and functional properties for various applications to researchers and industries, and (11) an organization to carry out exclusive research on tuber starches may be established in any of the TTC-growing countries.

Mengingat bahwa kenaikan ketersediaan energi alternatif belum dapat mengimbangipenurunan stok energi fosil, kenaikan harga bahan bakar minyak (BBM) di Indonesia tak terhindarkan.Kenaikan harga BBM tersebut diperkirakan memberikan dampak negatif terhadap biaya operasionalusaha perikanan tangkap, budidaya dan pengolahan. Makalah ini bertujuan untuk: menganalisiskeragaan usaha perikanan tangkap, menganalisis dampak kenaikan harga BBM terhadap usahaperikanan tangkap, dan merumuskan strategi kebijakan untuk mengantisipasi dampak kenaikan hargaBBM untuk jangka pendek dan menengah pada usaha perikanan tangkap. Untuk analisis-analisis ini,dipergunakan data-data sekunder yang diperoleh dari tiga sumber utama, yaitu statistik perikanantangkap, laporan-laporan terkait penggunaan BBM pada kapal perikanan dan laporan-laporan dampakkenaikan harga BBM pada periode sebelumnya. Hasil analisis menunjukkan: (1) Kenaikan harga BBMberdampak secara langsung proses produksi, distribusi dan konsumsi usaha perikanan; (2) Pelakuusaha perikanan melakukan usaha adaptasi dalam bentuk inovasi pembiayaan, pengurangan operasikegiatan penangkapan, penggunaan kapal pengangkut dan penjualan langsung yang memberikandampak lanjutan terhadap penurunan produksi dan penurunan pendapatan; (3) Strategi kebijakanyang dapat dipertimbangkan adalah: pertama, mendorong dan mempromosikan penggunaan energialternatif; kedua, mempertimbangkan daerah over fishing sebagai daerah konservasi; ketiga, penjaminanharga ikan berkualitas; dan keempat, peningkatan kapasitas sarana dan prasarana untuk penangananpasca panen. Kebijakan di hilir seperti penjaminan harga ikan berkualitas dan pengadaan sarana danprasarana untuk penanganan pasca panen direkomendasikan sebagai kebijakan kreatif yang dapatmemberikan dampak positif kepada pelaku usaha perikanan dan kinerja usaha perikanan secara umum.Title: Policy Anticipation to Cope With Fuel Price Dinamics inCapture FisheriesDue to the fact that the accumulating rate of alternative energies has not compensated thedecrease in stock of fossil energy, fuel price increased are unavoidable. Fuel price increases areexpected to bring negative impacts onoperationa costs of capture fisheries, aquaculture as well as fishprocessing. This paper aims to : (1) analyze the status of capture fisheries, (2) the impact of fuel priceincreased on capture fisheries activity and (3) formulate policy strategies to anticipate the impacts offuel price increased in the near future and long temperiod. This analysis used secondary data that havecollected from three main sources, namely Capture Fisheries Statistics, fuel consumption documentsof fishing vessels and reports on the impact fuel price increase of past period. Results shows that: (1)Fuel price increase impacts directly affected to production process as well as productsdistribution andconsumption; (2) Fishing vessel operators adapted to the situation through various approaches including financial innovation, reduction in fishing activities, deploying carrier vessels, and carrying out direct selling; (3) Policystrategy options consist on several points: firstly, promoting the alternative energy;secondly, converting overexploitedfishing grounds into conservation areas;thirdly, imposing quality –based pricing policies; and fourthly, increasing thecapacity of post-harvest handlingfacilities and infrastructure. Downstream policies such as price guaranty based onfish quality and provision of post-harvest facilities and infrastructure are considered as creative policies, which canpositively impact on fisheries performance.

The underutilization of African oil bean seed necessitated the study of its post-harvest operations. This work reviews the status of research on postharvest processes of African Oil Bean (AOB) seed. Information was sought through a search query with African oil bean post-harvest processing, packaging and storage as keywords on Google Scholar, internet, publishers' website, textbooks and oral interview with local processors. The results showed that researchers have focused on the fermentation, proximate, phytochemical, mineral and vitamins composition of AOB seeds. This study also revealed the dearth of research on characterization, improved variety, packaging, storage, value addition and oil extraction from AOB seeds. Research on postharvest handling, storage, packaging and processing of AOB seed is imperative for optimal utilization of the seed, and to prevent the prevalent post-harvest losses.

Tomatoes are one of the most widely produced and consumed vegetable in Nepal. Fungal pathogens deteriorate the quality and quantity of tomato and cause health hazards to the consumers as well as economic loss to the traders. This study was carried out to identify some fungal diseases associated with post-harvest deterioration of stored tomato fruits in Balkhu Agriculture and vegetable Market of Kathmandu, Nepal. Collected samples were cultured in Potato Dextrose Agar (PDA) media in complete randomized design. Fifteen species of fungi namely Alternaria alternata, A. solani, Aspergillus niger, Botrytis cinerea, Fulvum fulva, Colletotrichum truncatum, Curvularia spicifera, Fusarium oxysporum, Dipodascus geotrichum, Mucor mucedo, Penicillium chrysogenum, Phytophthora infestans, Boeremia exigua, Pythium aphanidermatum and Rhizopus stolonifer were identified. These were responsible for 14 different diseases of Alternaria fruit rot, Anthracnose, Black mold rot, Botrytis Bunch Rot, Damping off/ fruit rot, Drechslera mold, Fusarium rot, Mucor rot, Penicillum rot, Boeremia blight, Phytophthora rot, Rhizopus rot, Russet, and, Sour rot. The presence of these fungi and corresponding rot diseases on stored tomato indicates the need for management of fungi, farm sanitation and improved market in order to prevent field-to-storage transmission of pathogen.
