Growth Performance and Osmoregulation of Vaname Shrimp (Litopenaeus Vannamei) with Cultivation Media Engineering

Introduction

Growth performance and osmoregulation of vaname shrimp (litopenaeus vannamei) with cultivation media engineering. Explore optimized freshwater cultivation for Vaname shrimp (Litopenaeus Vannamei) using media engineering with bittern and salt to enhance growth performance and osmoregulation. Discover ideal mineral doses.

Abstract

Production of white shrimp (Litopenaeus vannamei) in 2024 is targeted by the Ministry of Fisheries and Marine Affairs to be increased by producing 2 million tons / year. However, in fact, in 2022 white shrimp production is 1.09 million tons, so to achieve the target, new technology and innovation are needed. The obstacle experienced with freshwater cultivation is the low mineral that plays an important role in the growth of white shrimp. To be able to cultivate white shrimp in fresh water, it is necessary to first conduct a study on the manipulation of aquaculture water with freshwater, salt and bittern components as mineral sources. The purpose of this study is to test the combination of components of artificial water media for white shrimp farming and analyze the mineral content. The study will be conducted from March to April 2024. The method used is an experimental method with Completely Randomized Design (CRD). Data collection is carried out by field observation and literature study. The research procedures carried out were bittern and salt collection and white shrimp sampling, media preparation, mineral test on water as culture media, white shrimp stocking, white shrimp rearing, morphology and survival rate tests and viscosity tests to review osmoregulation in white shrimp and data analysis. Data analysis was performed using Canonical Correlation Analysis (CCA) with PAST 4.03 software. The mineral content produced is directly proportional to the amount of dose given. The best dose of bittern in this study is in treatment C with a dose of 15 ml which has a calcium content of 45.2 mg/L, magnesium 155 mg/L, and potassium 73.89 mg/L.

Review

This study addresses a critical challenge in achieving Indonesia's ambitious white shrimp production target by exploring innovative cultivation media engineering for freshwater environments. The abstract clearly articulates the need for new technology to overcome the limitations of low mineral content in freshwater for *Litopenaeus vannamei*. The primary objective is to evaluate combinations of artificial water media, incorporating freshwater, salt, and bittern as mineral sources, and to analyze their mineral composition. This research is highly relevant to sustainable aquaculture practices, particularly in regions where access to brackish or marine water is limited, aiming to enhance shrimp growth performance and osmoregulation. The methodological approach outlined involves an experimental design using a Completely Randomized Design (CRD), scheduled for March to April 2024. Key procedures include media preparation, mineral testing, white shrimp stocking and rearing, followed by assessments of morphology, survival rate, and importantly, viscosity tests to infer osmoregulation. Data analysis is planned using Canonical Correlation Analysis (CCA) with PAST 4.03 software, which is an appropriate statistical tool for exploring relationships between multiple variables. While the abstract states the study "will be conducted" in 2024, it also presents a preliminary finding that mineral content is directly proportional to the dose given, highlighting a specific "best dose" of bittern (15 ml) that yielded notable calcium, magnesium, and potassium levels. While the preliminary mineral analysis results are promising for optimizing culture media, the abstract falls short in presenting actual biological outcomes. The title explicitly promises insights into "Growth Performance and Osmoregulation," yet the abstract's findings are solely focused on the mineral composition of the engineered water, rather than the shrimp's response to it. The full manuscript will need to thoroughly present and discuss the results related to shrimp growth (e.g., weight gain, specific growth rate, feed conversion ratio) and the detailed interpretation of osmoregulation through viscosity tests, clearly linking these biological endpoints to the varied media compositions. Additionally, the rationale for using "literature study" as a data collection method in an experimental design should be clarified, and the potential brevity of the two-month study period for comprehensive growth performance assessment might warrant further justification.
