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.

Abstract

This study was aimed to observe the survival rate (SR) and clinical signs, and the acute immune response of Pacific white shrimp (Litopenaeus vannamei), including total hemocyte count (THC), bacterial clearance, and prophenoloxidase (ProPO) activity due to infection with the Vibrio parahaemolyticus bacteria and its metabolites. Shrimp were infected by bacterial isolates with culture media (A), bacterial isolates without culture media (B), and metabolites suspensions from bacterial culture media (C) for 8 hours with observation every 2 hours. The results showed that experimental shrimps in groups A and B showed clinical signs and reduced SR, 24.44% and 62.22%, respectively. Experimental group C still showed the clinical signs but did not cause the mortality (SR 100.00%). The THC did not show significant changes, either based on experimental groups or duration of infection, but all groups tended to show decreasing THC at 8 hours post-infection. Bacterial clearance and ProPO activity also did not show significant differences between experimental groups or duration of infection at 8 hours post-infection. However, there was an increase in bacterial clearance activity at 6 hours post-infection in the experimental groups A and B. Based on the study results, the acute immune response in shrimp from all of the experimental groups did not show significant changes at 8 hours post-infection. However, group A significantly decreased SR compared to groups B and C.

Abstract

Penelitian ini bertujuan untuk mengidentifikasi faktor penyebab kematian massal ikan gurame (Osphronemus gouramy) di beberapa kolam budidaya di Tulungagung melalui pendekatan multifaktorial yang mencakup analisis kualitas air, komposisi plankton, pemeriksaan hematologi, histopatologi, dan deteksi molekuler patogen. Hasil pengukuran kualitas air menunjukkan kondisi lingkungan yang suboptimal, termasuk kadar oksigen terlarut rendah, konsentrasi nitrit tinggi, dan dominansi fitoplankton Oscillatoria sp. dengan kepadatan tinggi. Analisis plankton mengindikasikan potensi produksi microcystin yang bersifat hepatotoksik. Pemeriksaan histopatologi mengungkap kerusakan serius pada hati, ginjal, dan limpa, sedangkan profil hematologi menunjukkan anemia normositik normokrom dan leukositosis. Deteksi molekuler (PCR) memastikan keberadaan Infectious Spleen and Kidney Necrosis Virus (ISKNV) pada beberapa sampel, sementara patogen bakteri utama tidak terdeteksi. Temuan ini mengindikasikan bahwa mortalitas massal disebabkan oleh interaksi sinergis antara stres lingkungan akibat dominansi plankton toksik dan infeksi ISKNV, yang sesuai dengan konsep multiple stressor syndrome. Hasil penelitian ini menegaskan pentingnya pengelolaan kualitas air, pengendalian plankton toksik, dan pemantauan kesehatan ikan secara berkala untuk mencegah kejadian serupa di masa depan.
