Terubok fish is an estuarine fish that is significant among local fishermen because of high commercial value and it also constitutes to source of income for Terubok fishermen during its catching season. Therefore, due to high commercial value, Terubok fish has been subject to overfished and the population has been declining throughout the years. This study is carried out to analyse the efficiency performance of Terubok fisheries in Malaysia. A sample of actively Terubok fishermen was selected through stratified random sampling and the field survey has conducted at three different places in Sarawak. Data Envelopment Analysis (DEA) and Tobit Analysis were employed to determine the technical efficiency level and factors influencing technical efficiency among Terubok fishermen. The results of the study show that, most fishing units exhibit a low level of technical efficiency. This implies that either fishing inputs were used inefficiently, or insufficient inputs were used in fishing operations. The mean technical efficiency of the sample was estimated to be 0.304 using CRS Model, 0.406 using VRS Model and Scale Efficiency is 0.805. The determinant factors of efficiency among Terubok fishermen was among all, hours in a day, days spent in fishing per month, engine horsepower and fisherman association show positive sign towards efficiency contradictorily other determinant such as age, education, distance and length of vessels possess negative sign towards efficiency. These findings suggest that there’s urgent need to the efficiency level of the fishermen as this will indicate the impact of their living standard. With appropriate training and using more advanced technologies by the fishermen, the level of technical efficiency can be raised, segmented for inshore fisheries.

Research highlights the importance of potato crop, which occupies a prominent food and economic status in food security besides rice, wheat and corn at the local and global level. Despite the expansion of the cultivation of potato crop in Iraq in general and Ameriyah district in particular However, potato productivity remains substandard, this may be due to a lack of knowledge of the most efficient varieties and not to use productive resources at the levels at which technical, specialized and economic efficiency is achieved. Therefore, the aim of the research is to determine the technical, specialized and economic efficiency according to the cultivated seed category. The data envelope analysis (DEA) method was used to estimate technical, specialized and economic efficiency, assuming constant and variable capacity returns. As a result of the study, the Safrana variety achieved the highest average technical efficiency according to the stability of the yield and capacity efficiency in addition to achieving the highest average specialized and economic efficiency, The Lapadia variety achieved the highest average technical efficiency, assuming that capacity returns have changed. Therefore, we recommend the adoption of items that achieve higher efficiency and the need to redistribute the elements of production better and Achieving the optimum levels at which technical, specialized and economic efficiency is achieved and saving what has been wasted.
