Abstract

One of the problems in commona carp farming activities is ectoparasite infection which is thought to correlate with length, weight and condition of the fish. The aims of the research were to determine the species, prevalence, intensity and dominance of ectoparasites and to determine the correlation between the number of ectoparasites and the length, weight and condition factors of Najawa red carp (Cyprinus carpio Linneaus) fingerling at BPTPB Cangkringan. The research used laboratory observation method on randomly selected fish samples. Sampling was carried out for 3 weeks and a total of 27 individuals were examined. Ectoparasite observations were carried out on mucus samples from the body surface and gill sheets microscopically. The length and weight of each fish sample were measured and the results were used to calculate the condition factor. The correlation relationship was calculated between the number of ectoparasites and the length, weight and condition factors of the fish. The research results showed that five ectoparasites were found to infect fish samples with varying prevalence and intensity values, namely Trichodina sp., Dactylogyrus sp., Gyrodactylus sp., Glochidium sp. and Vorticella sp. Trichodina sp. has the highest prevalence, intensity and dominance compared to other parasites. The number of ectoparasites has a positive correlation with the length and weight of fish in the low category. In addition, a low negative correlation was found between the number of ectoparasites and fish condition factor. The results of this study indicate that ectoparasites are a factor that can influence the productivity of Najawa red carp cultivation.

Abstract

Aquatic ecosystems are very important for biodiversity and play a crucial role for the environment as well as for humans. Phytoplankton, the primary producers in this system, significantly contribute to oxygen production and CO2 absorption, making them crucial for global climate regulation. However, climate change marked by rising temperatures and unpredictable weather patterns has negatively impacted the abundance and distribution of phytoplankton, thereby threatening marine biodiversity and the stability of ecosystems. This study focuses on analyzing the impact of climate change on the abundance of phytoplankton in the oceans and identifying strategies to address it, through literature review. The research results indicate a significant decline in phytoplankton abundance, influenced by significant temperature changes from year to year. Effective mitigation strategies, including efforts to reduce greenhouse gases, protect biodiversity, and educate the public, are essential for preserving aquatic ecosystems. This research emphasizes the need for immediate and sustained action to protect marine biodiversity and ensure ecological balance.

Abstract

The hotate clam (Mizuhopecten yessoensis) is one of the clam species that lives in cold-temperature waters with the largest production in the Japanese region. However, the sustainability of this aquaculture is threatened by various factors, including ectoparasite infections that can affect the morphometric profile of the scallop. This study aimed to analyze the impact of ectoparasites on the morphometry of hotate clams in Funka Bay, Hokkaido, and to inventory the types of ectoparasites found. Samples of 25 individual hotate mussels were taken using random sampling techniques and morphometric measurements were taken using Image-J software. Ectoparasite infestation was categorized into four categories: free, low, medium and high. Analysis was conducted using One-Way ANOVA and Fisher's Pairwise Comparison follow-up test (P<0.05), as well as hierarchical cluster analysis based on the Bray-curtis similarity index visualized in a dendrogram. The results showed that there were two types of ectoparasites, namely Polydora sp. and Barnacles sp., with the dominance of Polydora sp. which was found in 17 individuals. Some morphometric distances such as AD, AE, BD, and CE showed significant differences between infestation categories. The dendrogram showed that the 'free', 'low', and 'medium' categories had high morphometric similarity (0.987), while the 'high' category showed lower similarity (0.96).

Abstract

ABSTRAK Penyakit Acute Hepatopancreatic Necrosis Disease (AHPND) merupakan salah satu ancaman utama dalam budidaya udang yang disebabkan oleh Vibrio parahaemolyticus pembawa plasmid toksin PirAB. Upaya pengendalian konvensional berbasis antibiotik telah memunculkan permasalahan resistensi antimikroba dan kerusakan mikrobiota usus. Artikel ini merupakan tinjauan pustaka yang bertujuan untuk mengevaluasi potensi mikroorganisme, khususnya genus Bacillus, sebagai agen biokontrol alternatif dalam mengendalikan AHPND. Berbagai riset yang dipublikasikan dalam sepuluh tahun terakhir dianalisis secara kritis untuk menilai efektivitas, mekanisme kerja, dan tantangan aplikatif probiotik mikroorganisme terhadap AHPND. Hasil analisis menunjukkan bahwa beberapa strain Bacillus, seperti B. subtilis, B. licheniformis, dan B. velezensis, mampu menekan infeksi AHPND secara signifikan melalui produksi senyawa antibakteri dan stimulasi imun udang. Artikel ini juga mengungkap adanya ketidakkonsistenan metodologis dalam pengujian efektivitas probiotik dan pentingnya harmonisasi eksperimen untuk pengembangan probiotik skala industri. Kajian ini memberikan perspektif ilmiah berbasis bukti mengenai peran mikroorganisme dalam akuakultur berkelanjutan bebas antibiotik. Kata kunci: AHPND, Bacillus, biokontrol, probiotik, Vibrio parahaemolyticus
