The study was conducted to estimate the post-harvest loss(PHL)of inland capture fisheries in Bangladesh based on the fishing venture i.e.,sole proprietorship,partnership and cooperatives using Questionnaire loss Assessment Method(QLAM).A total of 1339 fishermen were selected using stratified random sampling where 792,485,and 62 were involved in the sole proprietorship,partnership,and cooperatives types of fishing venture *** data were collected from thirty-nine districts across six divisions through the direct interview method covering 92 fish *** results indicated that Ashar(June-July)to Agrahayon(November-December)was the peak fishing period for every fishing *** study revealed that the high volumes of fishes were caught from haor for partnership and cooperatives while river was for sole *** study accounted lower PHL for cooperatives than that of sole proprietorship and partnership and found significance differences among them from Tukey’s pairwise *** estimated PHL was higher for Puti(Puntius chola)in sole proprietorship and partnership whereas Tengra(Gagata cenia)in cooperatives *** study suggests to expand the cooperatives fishing ventures widely in Bangladesh where the predominant factors(i.e.,longer harvesting duration,delaying in marketing the fishes and temperature,excess supply,and etc.)of causing PHL in this venture should be taken under consideration.

Yam “Kponan” (Dioscorea cayenensis-rotundata) is a popular staple food in Côte d’Ivoire. However, its rapid decay during conservation prevents regular supply of markets. The objective of this study was therefore to assess the impact of field cultivation and conservation practices on some physical quality parameters of “Kponan”. To this end, “Kponan” yam from three production areas (Bondoukou, Bouna, Kouassi-Kouassikro) was cultivated in each area. At maturity, physical parameters of yams at harvest and after 3 months of storage in field were analyzed. The results showed that injury was the most significant deterioration in yam harvest. The rate of injured yams was highest for hoe-harvested in Kouassi-Kouassikro area (16.67% - 22.22%) regardless of the origin of the cuttings. The main damage observed after the 3 months of storage was rots (22.86% - 60.00%) and weight loss (8.57% - 42.86%). However, yams stored in pits in Bouna zone had less damage (40% - 48.87%) than those stored under straw huts in Bondoukou locality (100%) and at shade under a tree in Kouassi-Kouassikro area (100%). In conclusion, the physical quality of “Kponan” in field is most affected by abusive use of herbicides during weeding and clearing, hoe harvesting and storage in the shade under a tree.
