Tuna long liners play a very important role in the export-oriented fisheries sector in Sri Lanka while contributing a reasonable foreign income to the country. Hence, the objectives of the study were to investigate the issues of by-catch, depredation, and authenticity of the export-oriented tuna value chain while exploring the transport and logistics issues of tuna supplies and to propose strategies to overcome the issues identified. Primary data was collected from fishers in two fisheries harbors, Dikkowita and Gandara, in the Western and Southern provinces, respectively. A pre-tested, structured questionnaire was administered to the fishermen who used to fish in the high seas and the Exclusive Economic Zone. Boat owners or crew members of multiday fishing boats (IMUL) were interviewed monthly, covering 20% of the boats in each harbor. The depredation index was 15.60, with an attack interval of 3.46 and a damage rate of 0.29. Issues such as depredation of attached hooks or bait, hooking of unwanted catch, dissolving of fish schools, wastage of time, fuel, and energy, and loss of moral strength among fishers were recorded. The unwanted by-catch, such as sea turtles, sharks, seabirds, and sailfish, reduced the harvest, while these non-targeted damages adversely impacted marine life. As suggested solutions to overcome the issues, dolphin pingers could be used to repel the harmful cetacean species, the crew members could be trained for cetacean identification and record keeping, and satellite tagging could be used to closely monitor the predatory species.

Developing a framework for assessing the economic performance of highway projects in Sri Lanka
(Sri Lanka Society of Transport and Logistics, 2023-08-26) Panditharatne, D; Gunaruwan, TL
Empirical evidence demonstrates that transport networks create positive and negative impacts on the economy and society. Therefore, assessing these impacts via project evaluations is essential. As evidenced in the literature, conducting project evaluations, post-operationalization, provides many benefits. However, many countries do not conduct post-project evaluations consistently, or these are performed for shorter periods, due to little emphasis on their importance in evaluating the socio-economic impact, methodological challenges, and unavailability of data on the project, especially in low-income countries. Sri Lanka is not an exception to this rule as many road projects are not evaluated post-operationalization. Hence, this paper focuses on developing a standardized framework for post-project evaluations of road projects considering both direct and indirect economic benefits, by utilizing a Cost-benefit analysis and a wider-economic impact assessment, respectively. The Southern Expressway has been selected as the case study to conduct an in-depth analysis, utilizing the above framework, as it is one of the most significant infrastructure projects in Sri Lanka.

Developing an average daily traffic (adt) estimation and prediction model for Sri Lankan roads
(Sri Lanka Society of Transport and Logistics, 2023-08-26) Madhushika, PGD; Gunathilaka, S; Gunaruwan, TL
This paper suggests a model to predict Average Daily Traffic (ADT) data of road segments in Sri Lanka where timely updated ADT data are not available. This methodology can be used to predict and estimate ADT data of both major and minor roads. Many previous studies have been conducted to estimate ADT only on specific road segments instead of considering the whole road network in the country. Initially, a road segment with a considerable length is selected for the study, and a model is developed to find the relationship between available ADT data of the particular road segment and associated factors which influence the ADT. These factors include social factors, economic factors, roadway and land use characteristics, availability of public transport, infrastructure development, etc. The most significant variables that affect ADT are identified, and corresponding weights are assigned for each variable through the developed regression model. Predicted accuracy of the model is validated through manual traffic counts. This proposed methodology can be applied for both major and selected minor roads and then expanded to the entire road network. This prediction model can be used to estimate ADT of road segments where updated ADT is not available, and data can effectively be used for transportation planning, capacity analysis, and infrastructure design, etc.
