Upaya Pencegahan Dan Penanggulangan Kematian Massal Ikan Di Danau Dan Waduk

Abstract: Degradasi kualitas perairan di danau dan waduk semakin meningkat menyebabkan terjadinya kasus kematian ikan secara massal. Untuk itu dilakukan kajian yang bertujuan untuk merumuskan upaya pencegahan dan penanganan kematian massal ikan di danau dan waduk, terutama bagi ikan-ikan budidaya, melalui telaah dan analisis berbagai literatur. Hasil kajian menunjukkan bahwa kasus kematian massal ikan dapat disebabkan oleh berbagai faktor, diantaranya: i) perairan kekurangan oksigen; ii) ikan mengalami keracunan akibat … Show more

“…The same thing for the phosphate parameter with a value above 0.2 mg/L which is categorized as eutrophic according to [24] classification was also found in the results of previous research by [26,27,28,29]. The eutrophic level of these two parameters is an indication that the carrying capacity of water has been exceeded to support aquaculture activities [30]. Overall, the recorded water quality at the artificial habitat location currently obtained is not much different from the description of the previous reservoir water quality conditions for the 2016-2020 and 2021 timeframes [11], except that current velocity and nitrate are not regulated in the standard.…”

“…The concentration of chlorophyll-a periphyton in both vertical and horizontal floating habitat artificial structures fluctuated and showed the same pattern, that the concentration was highest at a depth of 1.5 m from the water surface and the lowest at a depth of 8 m, even though the water brightness value was below 2 m. Chlorophyll-a was observed as a representation of the presence of periphyton microalgae attached to each attractor media (raffia cord, palm fiber, strapped plastic band, coconut leaves, plastic bottle packaging). [30] described phototrophic periphyton as microbial communities attached to the surface of solid materials underwater and their presence controlled by light energy for the process of photosynthesis. These phototrophic oxygenic microorganisms produce energy and reduce carbon dioxide, providing organic substrates and oxygen in the waters.…”

“…Fenomena ini biasanya ditandai dengan mulai mabuk atau mengambangnya ikan di permukaan air, bahkan lebih parah lagi matinya ikan yang hidup di dasar perairan. Kematian secara massal ikan budidaya sistem KJA mencapai kerugian milyaran rupiah akibat upwelling sisa pakan yang mengendap pada dasar danau berpotensi besar sebagai racun pada ikan-ikan yang berada di KJA maupun dipermukaan perairan, upwelling sendiri mempunyai massa air yang beracun dan juga beroksigen rendah yang mengakibatkan munculnya peristiwa kematiaan massal pada ikanikan di perairan maupun di KJA (Sulaiman et al, 2020).…”

“…Menurut Pinem (2020), Dampak terhadap lingkungan yang ditimbulkan oleh kegiatan budidaya dengan sistem keramba jaring apung yaitu peningkatan kandungan nutrien di perairan yang berasal dari sisa pakan yang tidak termakan, ekskresi dan feses ikan, serta kemungkinan adanya penurunan terhadap kualitas perairan, lingkungan dan kondisi kesehatan ekosistem yang dapat menyebabkan eutrofikasi dan terjadinya blooming plankton yang dapat menyebabkan kematian massal pada ikan. hal ini senada dengan pernyataan Sulaiman et al (2020) yang menyatakan bahwa Kematian missal ikan diperairan umumnya lebih banyak terjadi pada badan air yang daya dukung perairannya telah berlebih penggunaannya. Namun menurut Rahayu (2017), upaya memaksimalkan pengembangan budidaya ikan kerapu harus dilakukan secara rasional dan berkelanjutan dengan cara analisis daya dukung dikarenakan, budidaya ikan kerapu sebagian besar yang masih menggunakan teknologi sederhana, mengalami kendala seperti penyakit, keterbatasan pakan ikan rucah sampai penuruan daya dukung perairan.…”
