Abstract

Dirjen KKP mulai memberlakukan larangan penggunaan induk asal tambak sejak bulan Mei 2019 dan mewajibkan menggunakan indukan yang berasal dari breeding program. Penelitian ini bertujuan untuk mengetahui bentuk kurva pertumbuhan, mendapatkan model matematika yang paling tepat untuk menduga dan menggambarkan pertumbuhan calon induk udang vaname dan hasil persilangannya sehingga didapat hasil calon induk udang terbaik. Adapun model yang digunakan model Richards, MMF, Gompertz, Logistik dan Von Bertalanffy. Metode penelitian yang digunakan adalah metode studi kasus yang dianalisis secara deskriptif dengan objek penelitian yaitu udang vaname Galur G Jantan, Galur G Betina, Galur R Jantan, Galur R Betina, Hybrid GR Jantan, Hybrid GR Betina, Hybrid RG Jantan dan Hybrid RG Betina. Variabel yang diamati pada objek penelitian adalah bobot badan selama 201 hari. Data dianalisis menggunakan SAS, dibuat grafik serta kurva pertumbuhan, dilihat nilai koefisien korelasi (r) dan galat baku (Se) serta nilai heterosisnya. Hasil yang diperoleh yaitu (1) bentuk kurva pertumbuhan berbentuk sigmoid, dengan titik infleksi pada minggu ke 14, (2) model matematika kurva pertumbuhan terbaik adalah model Richards dan MMF dengan nilai koefisien korelasi yang tinggi (0,997-0,999) serta galat baru (standar error) yang rendah (±0,76 hingga ±1,18), (3) heterosis efek terbaik merupakan hasil persilangan jantan Galur G dan betina Galur R dengan presentase nilai heterosis untuk karakter bobot yaitu 17,24% dan 17,58%. The Director General of KKP has started to enforce a ban on the use of broodstock from ponds since May 2019 and requires the use of broodstock from breeding programs. This study aims to determine the shape of the growth curve, obtain the most appropriate mathematical model to predict and describe the growth of prospective vannamei shrimp broodstock and the results of their crosses so that the best prospective shrimp broodstock results are obtained. The model used is the Richards, MMF, Gompertz, Logistics and Von Bertalanffy models. The research method used was the case study method which was analyzed descriptively with the research objects namely vaname shrimp Male G Line, Female G Line, Male R Line, Female R Line, Male GR Hybrid, Female GR Hybrid, Male RG Hybrid and Female RG Hybrid. The variable observed in the research object was body weight for 201 days. The data were analyzed using SAS, graphs and growth curves were made, the correlation coefficient (r) and standard error (Se) were seen and the heterosis value. The results obtained are (1) the shape of the growth curve is sigmoid, with an inflection point at week 14, (2) the best growth curve mathematical model is the Richards and MMF model with a high correlation coefficient value (0.997-0.999) and a new error (standard error) is low (±0.76 to ±1.18), (3) the best heterosis effect is the result of crosses of male G lines and R female lines with the percentage of heterosis values for character weights, namely 17.24% and 17.58%.

Abstract

GMO is a product of biotechnology through genetic engineering techniques. This can be done to increase food availability and reduce production costs, especially by manipulating the genes and chromosomes of cultivated species. In invertebrates such as shrimp, the application of gene transfer is still limited to the recognition and expression of foreign genes and focuses on increasing disease resistance. Among several gene transfer methods (microinjection, electroporation and transfection), transfection method is the most effective method to be applied to shrimp. It is characterized by high hatching data and is not toxic. In addition, the use of GMO in aquaculture is a highly controversial issue due to many environmental and health issues. This journal will discuss gene manipulation by means of gene transfer to improve shrimp culture.

Abstract

The Pacific white shrimp, Litopenaeus vannamei, is a key species in global aquaculture, valued for its rapid growth and high market demand. Understanding the molecular mechanisms of gonadogenesis and primordial germ cell (PGC) migration in this species is vital for optimizing breeding programs. This review consolidates current knowledge on these processes, highlighting the role of the vasa gene as a germ cell marker. Vasa expression was tracked from fertilized eggs to juveniles aged four months, revealing the conserved DEAD-box helicase motif essential for germ cell development. Early detection of vasa messenger ribonucleic acid (mRNA) in developmental stages such as nauplius and zoea indicates its role in germ cell specification. By the post-larval stages, PGCs formed clusters associated with somatic gonadal precursor cells (SGPs), which support PGC migration and development. Quantitative polymerase chain reaction (qPCR) and reverse transcription PCR (RT-PCR) analyses demonstrated dynamic changes in vasa gene expression, suggesting critical windows for PGC proliferation and differentiation. Comparative studies with other species, such as Macrobrachium rosenbergii and Fenneropenaeus chinensis, emphasize the evolutionary conservation of germ cell development mechanisms. These insights are crucial for enhancing reproductive management and sustainability in shrimp farming, facilitating targeted interventions to improve breeding efficiency and hatchery success.
