The study determined the efficiency and performance of the distribution chain of marine capture fisheries in Lucena Fish Port Complex, Lucena City, Philippines. A survey using a pre-tested questionnaire was conducted among 125 respondents consisting of fishermen, traders, truckers, wholesalers and retailers. Simple random sampling was used to identify the fishermen, traders and retailers while complete enumeration was done in the case of truckers and wholesalers. Descriptive, product flow, value chain and cost and return analyses were employed in the study. Based on the performance measures used in the study, including the gross margins computed, the performance of the distribution and transportation system of marine capture fisheries products in Lucena Fish Port Complex can be considered inefficient due to high transportation rates, high spoilage rate, and longer traveling hours than what is expected. The study recommended technology development for improved operations, introduction of the open bidding system to prevent information asymmetry, practice of responsible fishing, key players to assume other roles in the chain, planning ahead the use of alternative roads, ensuring proper management practices, construction of paved roads. securing fishing permits and full utilization of the cold storage facility.

Prior studies have demonstrated comparable pregnancy outcomes in donor-egg IVF cycles using vitrified oocytes. Our aim was to investigate the laboratory and clinical outcomes using vitrified and then immediately thawed oocytes obtained from women in a range of age-groups undergoing IVF. A prospective and randomized clinical trial was conducted. Non-donor women undergoing IVF were enrolled in the study. Their oocytes were randomly assigned to either routine treatment or freezing with thaw 30-60 min later, and then all oocytes underwent ICSI fertilization at the same time. Only embryos from the freeze/thaw group were transferred. Laboratory outcomes (fertilization rates (FR), embryo quality) were compared among sibling oocytes. Of the 12 enrolled women, the median age was 33.5 years. The median number of oocytes was 18 (range 12-42) and median maturation rate was 79.9%. The median thaw survival rate in the vitrified group was 75% (range 25-100). The FR and number of good quality day 3 embryos (>6 cells, no fragmentation) were not different between the fresh and vitrified groups (p=0.24 and 0.06, respectively). There were 5 clinical pregnancies (4 on-going and 1 missed abortion). In non-donor IVF cycles, vitrified oocytes have comparable laboratory and pregnancy outcomes compared to fresh oocytes. Oocyte vitrification appears to be a promising modality for women of all ages, not only donor-cycles.
