Abstract

Betta dennisyongi, locally known as Jielabu fish, is an endemic ornamental species originating from southwest Nanggroe Aceh Darussalam, Indonesia. The fish currently faces increasing exploitation and habitat degradation which raise conservation concerns and emphasize the need for domestication efforts. This study aimed to determine an appropriate stocking density for the early culture of B. dennisyongi. The research was conducted from October to December 2023 using a completely randomized design with four stocking densities (1, 2, 3, and 4 fish L⁻¹) with three replications. Juvenile fish collected from the wild were acclimated and reared for 60 days in 10-L aquaria. Biological parameters measured included survival, specific growth rate, length gain, weight gain, feed conversion ratio, and feed efficiency, while water quality was monitored periodically. Stocking density significantly affected survival rate and growth (p < 0.05) of B. dennisyongi, with the lowest density (1 fish L⁻¹) producing the most favorable performance, while densities of 3–4 fish L⁻¹ resulted in reduced outcomes. Feed conversion ratio and feed efficiency did not differ significantly among treatments (p > 0.05). All measured water quality parameters remained within acceptable ranges for Betta fish culture. Overall, the study indicates that lower stocking densities support better biological responses, and that 1 fish L⁻¹ is the most suitable for cultivation, while 2 fish L⁻¹ may serve as an acceptable alternative for practical application. These findings provide a foundation for developing effective domestication protocols and support conservation-oriented aquaculture of this vulnerable endemic species. Betta dennisyongi, yang dikenal secara lokal sebagai ikan Jielabu, merupakan spesies ikan hias endemik dari wilayah barat daya Nanggroe Aceh Darussalam, Indonesia. Peningkatan pemanfaatan dan degradasi habitatnya telah menimbulkan kekhawatiran dalam kegiatan konservasi dan menekankan perlunya upaya domestikasi. Penelitian ini bertujuan untuk menentukan padat tebar yang sesuai untuk pemeliharaan awal B. dennisyongi. Penelitian dilakukan pada bulan Oktober hingga Desember 2023 menggunakan rancangan acak lengkap dengan empat padat tebar (1, 2, 3, dan 4 ekor L⁻¹) masing-masing dengan tiga ulangan. Benih ikan yang dikumpulkan dari alam diaklimatisasi dan dipelihara selama 60 hari dalam akuarium berkapasitas 10 L. Parameter biologis yang diukur meliputi kelangsungan hidup, laju pertumbuhan spesifik, pertambahan panjang, pertambahan bobot, rasio konversi pakan, dan efisiensi pakan, sedangkan kualitas air dipantau secara berkala. Padat tebar berpengaruh nyata terhadap kelangsungan hidup dan pertumbuhan (p < 0.05) B. dennisyongi, di mana padat tebar terendah (1 ekor L⁻¹) memberikan performa terbaik, sedangkan padat tebar 3–4 ekor L⁻¹ menghasilkan performa yang lebih rendah. Rasio konversi pakan dan efisiensi pakan tidak berbeda nyata antarperlakuan (p > 0.05). Seluruh parameter kualitas air berada dalam kisaran yang sesuai untuk budidaya Betta fish. Secara keseluruhan, penelitian ini menunjukkan bahwa padat tebar rendah mendukung respons biologis yang lebih baik, dan 1 ekor L⁻¹ merupakan padat tebar yang paling sesuai, sementara 2 ekor L⁻¹ masih dapat diaplikasikan. Temuan ini menjadi dasar bagi pengembangan protokol domestikasi yang efektif dan mendukung budidaya yang berorientasi pada konservasi bagi spesies endemik rentan ini.

Abstract

Aeromonas hydrophila mampu menyebabkan terjadinya infeksi dan kematian ikan botia dalam waktu yang relatif singkat pada konsentrasi yang tinggi, terbukti dengan konsentrasi 108 selml-1 menyebabkan 50% ikan uji mati. Hasil pengamatan histopatologi pada ikan terinfeksi menunjukkan ginjal yang mengalami degenerasi hyaline, munculnyavakuola yang disebabkan lisis pada glomerulus dan kemudian hancur, nekrosis pada glomerulus, terdapat banyak koloni bakteri A.hydrophila didalam ginjal, serta terjadi infiltrasi limfosit. Sel hati tidak terlihat jelas karena tertutup infiltrasi limfosit dan koloni bakteri A.hydrophila yang sangat banyak, nekrosis yang menyebabkan vakuola, terdapat infeksi sekunder bakteri yang belum teridentifikasi, serta terjadi cloudy swelling. Pada bagian insang, nekrosis lamela primer menyebabkan munculnya vakuola, kongesti pada lamela primer dan edema pada lamela sekunder, infiltrasi limfosit, poliferasi sel/fusi lamela serta hyperplasia pada lamela primer. Sementara itu pada ikan botia yang terinfeksi A.hydrophila tetapi kemudian diobati, ginjal mengalami perbaikan glomerulus dan kapsula bowman sehingga terlihat jelas, tubuli berbentuk seperti donat dengan corak titik dan garis, tidak ada lagi nekrosis dan vakuola, tidak ditemukan lagi koloni bakteri, terjadi perbaikan hyaline yang mengalami degenerasi, jaringan hematopoietic (pembentuk sel-seldarah merah) terlihat jelas dengan inti yang bulat. Pada bagian hati, tidak ditemukan lagi koloni bakteri A.hydrophila dan bakteri sekunder lainnya sehingga hepatosit terlihat jelas dengan bentuk polyhedral dengan inti 1-2, jumlah eritrosit terlihat normal, karena tidak ada lagi infiltrasi limfosit. Akan tetapi masih terdapat penyumbatan pada vena centralis yang dipenuhi oleh eritrosit. Pada insang tidak ada lagi nekrosis dan vakuola pada lamela primer sehingga jaringan terlihat solid, namun ditemukan infeksi sekunder parasit Monogenea sp. Tidak ada lagi infiltrasi limfosit, lapisan epithelium terlihat 1-2 lapis, tidak ada lagi edema dan fusi lamela sehingga lamela tampak jelas dengan ukuran panjang yang bervariasi.

Abstract

The viral nervous necrosis (VNN) is betanodavirus of the family Nodaviridae with acute infection and associated with high levels mortality up to 100% of numerous larval-stage marine and freshwater fish species. The danger signals of viral infection that are capable of activating APCs (Antigen Presenting Cells), furthermore produced molecules protein receptors such as interferon and heat shock proteins. Stimulating interferon type I (IFN I) induce several antiviral molecules, further binding the actin cytoskeleton to reach the site of infection. This study demonstrated a correlation between increased levels of Hsp70 (heat shock proteins) and actin filamentous (β-actin) within invasion wild-type isolate of ssRNA VNN from Asian Seabass (L. calcalifer) juvenile. Furthermore, expression of Hsp70 and actin as an indicator or biomarker of stressed states in fish. The reverse transcriptase polymerase chain reaction (RT-PCR) method used to finding expression Hsp70 and β-actin. Whereas nested RT-PCR used for VNN genes. The up-regulation of Hsp70 was observed on the brain tissue higher than eye tissue of sample positive infected VNN. Whereas different expression of β-actin, β-actin receptor expression tends to be stable in the organs of the brain and eye, both invaded VNN or normal, while on the eye, the ratio slightly increased based on the intensity of the band. The research shows that altered expression of heat shock protein 70 and beta-actin gene receptors in the target organs that response to invasion VNN at Asian seabass (L. calcalifer) juvenile. Alteration expression of heat shock protein 70 and beta-actin can be used as an indicator or biomarker of stress cells, especially from VNN invasion at fish.
