Fisheries Management of Terapon puta (Small-Scaled Terapon) from Lake Temsah, Egypt
A study on the mortality rates of Terapon puta from Lake Temsah revealed high levels of exploitation. Growth parameters were estimated using the von Bertalanffy growth model. The total mortality rate (Z) was calculated at 2.116 year⁻¹, with natural mortality (M) at 0.481 year⁻¹ and fishing mortality (F) at 1.64 year⁻¹. This corresponds to an exploitation ratio (E) of 0.77, indicating that a substantial proportion of the stock is harvested annually. The length at first capture (Lc) was estimated at 11.2cm. Further analysis using the relative yield per recruit model demonstrated that the current fishing pressure on T. puta in Lake Temsah is unsustainable. Urgent management interventions are therefore required, including the implementation of minimum size limits, the establishment of fishing quotas, and the designation of protected areas, in order to ensure the long-term sustainability and conservation of this important fishery resource.
