“…Sifat ikan budidaya banyak dimodifikasi dengan tujuan meningkatkan efisiensi produksi. Beberapa tujuan diterapkannya RG pada ikan budidaya antara lain untuk meningkatkan resistensi terhadap penyakit sehingga meningkatkan kelangsungan hidup (Han & Chen, 2019;Lo et al, 2014;Yazawa et al, 2006), meningkatkan toleransi dingin untuk memperluas jangkauan geografis untuk produksi (Shears et al, 1991), memodifikasi proses metabolisme inti (Alimuddin et al, 2005;Kabeya et al, 2016), dan mengurangi keluaran limbah (Hostetler et al, 2005), serta perubahan fenotip dan respon fisiologis (Devlin et al, 2020). Saat ini juga dikenal teknik genomeediting yang sedang dieksplorasi untuk mengubah sifat-sifat penting seperti ketahanan terhadap penyakit dan pematangan seksual (Gratacap et al, 2019).…”

Pemerintah telah mengesahkan Undang-Undang Nomor 21 Tahun 2019 yang mengatur tentang karantina hewan, ikan dan Tumbuhan. UU ini merupakan penyempurnaan dari peraturan sebelumnya yang dinilai sudah tidak relevan dengan kondisi terkini terutama terkait penerapan bioteknologi modern yang telah banyak diaplikasikan di bidang perikanan. Salah satu bab penting yang menjadi bagian dalam penyempurnaan UU ini adalah Bab 5 yang membahas tentang pengawasan dan pengendalian produk rekayasa genetik, sumber daya genetik, agensia hayati, jenis asing invasif, tumbuhan dan satwa liar, serta tumbuhan dan satwa langka. Bab 5 dirasa penting dan perlu dikaji lebih mendalam khususnya tentang sumber daya genetika ikan agar petugas di lapangan mampu melaksanakan tugas pengawasan sesui dengan kaidah keilmuwan dan batasan-batasan yang diamanatkan dalam UU No. 21 Tahun 2019. Oleh karena itu di dalam tulisan ini akan diuraikan tentang konsep dan batasan sumberdaya genetik ikan; materi genetik dan konsep keragaman genetik, potensi masalah yang ada.The government has passed Law No. 21 of 2019 which regulates animal, fish and plant quarantine. This law is a refinement of the previous regulation which was deemed irrelevant to current conditions, especially regarding the application of modern biotechnology which has been widely applied in the fisheries sector. One of the important chapters that is part of the improvement of this Law is Chapter 5 which discusses the supervision and control of genetically engineered products, genetic resources, biological agents, invasive alien species, wild plants and animals, and rare plants and animals. Chapter 5 is considered important and needs to be studied more deeply, especially regarding fish genetic resources so that officers in the field are able to carry out their supervisory duties in accordance with the scientific principles and limits mandated in Law no. 21 of 2019. Therefore, in this paper, the concepts and limitations of fish genetic resources and diverisity, genetic material, potential problems that exist are described.

“…Feed intake in fish is influenced by numerous abiotic and biotic factors such as water temperature, O 2 , CO 2 , pH, ionic composition and hardness, ammonia, nitrite, and nitrate levels, water flow rate, photoperiod, rearing density, genetic manipulation, exercise or feed composition ( Thorarensen and Farrell, 2011 ; Saravanan et al, 2012a ; Saravanan et al, 2012b ; Ende et al, 2016 ; Afonso, 2020 ; Bayley et al, 2020 ; Colombo, 2020 ; Devlin et al, 2020 ; Kristiansen et al, 2020 ). The impacts of the above-mentioned factors are comprehensively studied for at least several aquaculture species and tailored to the species-specific requirements.…”

There is a tendency to farm fish in low turbidity water when production takes place in the land-based recirculating aquaculture systems (RAS). However, the effect of water turbidity on stress and performance is unknown for many species cultured in RAS. The effect of different turbidity treatments as Formazine Attenuation Units (0 FAU, 15 FAU, and 38 FAU) on feed intake performance (latency, total feeding time, and total feed intake) and physiological blood stress parameters (cortisol, lactate, and glucose) in medium-sized pikeperch ((Sander lucioperca) n = 27, undetermined sex and age) of initial body weights of 508.13g ± 83 g (at FAU 0, 15 and 38, respectively) was investigated. The rearing system consisted of 9 rectangular tanks (200 L per tank). Fish were housed individually (n = 1, per tank, n replicates per treatment = 9). All tanks were connected to a recirculation system equipped with a moving bed biofilter. Feed intake in pikeperch kept at low turbidity (0 FAU) was 25% lower than pikeperch kept at high turbidity (38 FAU) (P<0.01) and also significantly (10.5%) lower compared to feed intake in pikeperch kept at intermediate turbidity (15 FAU) (P<0.01 for 0 FAU vs 15 FAU, feed intake sign. Value as the main effect is P<0.01). Pikeperch kept at low turbidity showed significantly slower feeding response (latency time) towards pellets entering the tank, shorter feeding times (both P< 0.05), and higher glucose blood concentration (73%) in contrast to pikeperch kept at highest turbidity. A reduction of 25% feed intake has obvious economic consequences for any fish farm and present data strongly emphasize the importance of considering the species-specific biology in future RAS farming.
