Carrying Capacity of Litopenaeus vannamei Ponds Based on Water Quality Parameters at Purworejo Village, Pasir Sakti Subdistrict, East Lampung Distric

Introduction

Carrying capacity of litopenaeus vannamei ponds based on water quality parameters at purworejo village, pasir sakti subdistrict, east lampung distric. Evaluate Litopenaeus vannamei pond carrying capacity in East Lampung based on water quality (DO, pH, nitrite). Find optimal stocking (80-100 shrimp/m²) for sustainable aquaculture.

Abstract

This study evaluates the carrying capacity of Litopenaeus vannamei ponds based on water quality parameters in Purworejo Village, East Lampung, Indonesia. Water samples were collected from five ponds over a 90-day culture period, measuring physicochemical parameters including temperature, pH, dissolved oxygen (DO), salinity, ammonia, nitrite, and hardness. Results showed temperature ranging from 28 to 31°C, pH 7.5 to 8.2, DO 6.8 mg/L, salinity 15–22 ppt, ammonia 0.02 to 0.07 mg/L, nitrite 0.05 to 0.12 mg/L, and hardness 1,200 to 2,300 mg/L. Most values were within the optimal ranges for vannamei shrimp culture according to FAO and national standards, although DO fluctuations and elevated nitrite levels may constrain stocking density. These findings indicate that the studied ponds remain suitable, with an estimated optimal carrying capacity of 80–100 shrimp/m². This study provides baseline data for water quality management and sustainable stocking strategies in vannamei shrimp aquaculture at Purworejo Village, Pasir Sakti Subdistrict, East Lampung District, East Lampung.

Review

This study presents a timely and relevant evaluation of the carrying capacity of *Litopenaeus vannamei* ponds in Purworejo Village, East Lampung, a critical aspect for sustainable aquaculture development. By focusing on a comprehensive suite of water quality parameters over a 90-day culture period, the research aims to provide essential baseline data for local farmers and policymakers. The methodical approach of sampling and measuring physicochemical parameters across five ponds directly addresses the objective of assessing environmental suitability for shrimp culture in the specified region. The abstract effectively outlines the key findings, indicating that most water quality parameters, including temperature, pH, salinity, ammonia, and hardness, generally fall within optimal ranges for *L. vannamei* according to FAO and national standards. This suggests a suitable environment for shrimp farming in the area. Crucially, the study identifies potential limiting factors, specifically dissolved oxygen (DO) fluctuations and elevated nitrite levels, which are noted as constraints on stocking density. These observations lead to an estimated optimal carrying capacity of 80–100 shrimp/m², offering practical guidance for maximizing production while mitigating environmental stress. Overall, this research provides valuable, localized data that can inform immediate water quality management and stocking strategies in the study area. While the abstract clearly states the findings, a full paper would benefit from a more detailed explanation of the methodology employed to *derive* the optimal carrying capacity (80–100 shrimp/m²) from the observed water quality parameters, especially given the identified constraints. This would strengthen the scientific basis of the recommendation. Nevertheless, the study serves as an important foundation for sustainable aquaculture practices and sets the stage for future investigations into the dynamic interplay between water quality, stocking density, and shrimp productivity in this region.
