Serdang Bedagai Regency has fisheries and marine potential demersal species of stingray in TPI Tanjung Beringin. The current study used a survey and descriptive method, accompanied by sample collection and morphology identification, as well as determining the rate explotation of fish landed in TPI Tanjung Beringin. A total of five species were successfully identified: Neotrygon kuhlii, Brevitrygon heterura, Aetoplatea zonura, Maculabatis macrura and Rhynchobatus australiae. The most dominant stingray species landed in TPI Tanjung Beringin namely of Neotrygon kuhlii, so that condition was an analysis of Neotrygon kuhlii weight length relationship of fish and body weight is negative allometric growth is more dominant than weight gain. The growth rate Von Bertalanffy is L ∞ (infinity) value is 300.30 mm, K value is 0.42 and t0 value is -0.68, the fish growth can be influenced by internal and external factors. Mortality and exploitation rate of Neotrygon kuhlii total mortality (Z) value is 1.01, natural mortality (M) value is 0.59408, fishing mortality (F) value is 0.4192 and exploitation rate is 0.7105 as long as indicators high fishing mortality and decreasing natural mortality indicate a state of growth overfishing.

Stingrays are a group of fish that have high economic potential landed at TPI Tanjung Beringin. The dominant type of stingray landed at TPI Tanjung Beringin is the Dwarf Whipray (Brevitrygon heterura) or commonly called Tuka-Tuka by the local community. This research wa carried out during July and September of 2021 at TPI Tanjung Beringin, survey method with a census technique, namely a method by seeking various information and various facts regarding the biological aspects. This study aims to determine the growth and exploitation rate of the dwarf whipray. There were 82 dwarf whipray, which were then measured for length and weight. The results of the study concluded that dwarf whipray (Brevitrygon heterura) which landed in TPI Tanjung Beringin had a negative allometric growth pattern, namely length growth was greater than weight growth. The exploitation status of the dwarf whipray (Brevitrygon heterura) in the waters of the Malacca Strait is classified as overfishing.

Sustainable stingray stock catches and increasing the potential that these fish populations may become overfished this may have a negative impact on the size of fish stocks. In order to estimate stock models and prospective resources of stingrays in the seas of the Malacca Strait, the descriptive technique was utilized to collect secondary data. The necessary to conduct stock dynamics research that examines the exploitation rate of stingrays. Based on the Schaefer model, obtained the value of sustainable potential (MSY) for Stingray resources (Dasyatis sp.) at Tanjung Beringin fishing port of 37,24625 tons/year and the optimum effort value of 148,6119 trips/ years. The percentage of stingray resource utilization rate which landed in Tanjung Beringin TPI during the last 5 years has an average value of 0,925% and an effort level of 1,234%. TAC is 29,797 tons/year, shows that fishing can still be increased to get more optimal results. The value of the allowable catch must be below the MSY value which is 80%. The average allowable catch of stingray (Dasyatis sp.) is 80% of the MSY. This means that fishermen’s catches can still be optimized, but must not exceed MSY limit.
