The purpose of this study to analyze the characteristics of carrageenan seaweed cultivated with bag and non-bag cultivation systems and different seed weights. The research was conducted in the waters of Bone Bay and the Laboratory of the Indonesian Center for Brackish Water Cultivation and Fisheries Extension in Maros. This study used a factorial completely randomized design (CRD) consisting of factor A (using bags and non-bags), and factor B (seed weight 15, 50, 75, 100, and 125 g). The results showed that the cultivation method factor, seed weight factor, and their interaction had an effect on carrageenan yield, gel strength, ash content and water content (P <0.05). Different cultivation systems with different initial seed weight combinations showed different best results for each parameter. The highest value of yield of carrageenan was observed in the bag culture system with a seed weight of 100 g, namely 29.18 ± 1.10%. The highest value of gel strength was observed in the non-bagged cultivation system with a seed weight of 75 g, namely 1344.69 ± 18.43 g/cm2. The highest value of ash content was found in the non-bagged cultivation system with 125 g of seed weight, namely 30.02 ± 0.13%. The highest value of water content was found in the bag culture system at a seed weight of 15 g, namely 38.63 ± 0.26%.

The purpose of this study was to investigate infectious diseases in rearing spiny lobster Panulirus spp. that were kept in floating net cages at Tanjung Putus, Lampung. The research method involved sampling five spiny lobsters in floating net cages, observation of clinical symptoms, bacterial isolation, identification of bacteria, detection of Milky Hemolymph Disease of Spiny Lobster (MHD-SL) through polymerase chain reaction (PCR) analysis and histopathology. The sampling location was at PT. Saibatin Perikanan Indonesia. The bacteria Vibrio parahaemolyticus and Vibrio alginolyticus were detected. Five lobsters were infected by MHD-SL, characterized by milky white hemolymph. All five lobster samples were positively infected with Milky Hemolymph Disease of Spiny Lobster (MHD-SL) through PCR analysis. Histopathological observations showed pathological microanatomical changes in the lobster hepatopancreas tissue, indicating that the tissue changes, in the form of encapsulation and infiltration were due to Rickettsia-like bacteria (RLB) infection.

This study aimed to analyze the effect of biofloc on the Vibrio composition in water and shrimp gut, as well as the growth performance and microvilli of Pacific white shrimp (Penaeus vannamei). Shrimp post-larvae measuring 0.66 ± 0.02 g were reared in a glass aquarium (working volume 22 L) of 6 units with a density of 150 shrimp m-3 for 28 days. The treatments included rearing in the biofloc system with C/N ratio 10, and without a biofloc system as a control. The results showed that Vibrio was highly prevalent in the control gut (4.13%) and biofloc water (3.77%), but only a few were found in the control water (0.16%) and biofloc-treated gut (0.11%). V. hepatarius (1.10%) and V. nereis (1.06%) were found to dominate the Vibrio bacterial community in the biofloc system maintenance media, while Vibrio sp. Hep-1b-8 (2.26%) and V. parahaemolyticus (0.80%) known as a pathogenic bacteria dominated the control shrimp gut. The biofloc system significantly increased the digestive enzyme activity, growth performance, and microvilli length in the shrimp gut. In conclusion, the application of a biofloc system in shrimp culture can affect the composition and abundance of bacterial communities in both the culture environment and the shrimp gut, and improve growth performance with higher digestive enzyme activity and longer microvilli in the gut. \u0000  \u0000Keywords: biocontrol, biofloc, microbiota, shrimp, Vibrio \u0000  \u0000ABSTRAK \u0000  \u0000Teknologi bioflok menunjukkan dampak positif pada kegiatan budidaya udang vaname dengan mengendalikan bakteri patogen salah satunya Vibrio.

Hasil pengamatan menunjukkan kelimpahan Vibrio yang cukup tinggi pada usus perlakuan kontrol (4.13%) dan air perlakuan bioflok (3.77%), tetapi sangat sedikit ditemukan pada air perlakuan kontrol dan usus perlakuan bioflok. Selanjutnya, V. hepatarius (2.26%) dan V. nereis (1.06%) terdeteksi mendominasi komunitas bakteri Vibrio di media pemeliharaan pada sistem bioflok, sedangkan Vibrio sp.

Because water quality can be maintained at an optimal level for fish in the system to enhance farming productivity. This study was conducted to evaluate the effects of fish density on the nursery stage of red tilapia in a small-scale aquaponic system. The study was conducted using a completely randomized design at three levels of stocking density, namely 250 fish/m2, 375 fish/m2, and 500 fish/m2 of red tilapia at an initial size of 6.8 ± 0.35 cm, with 30 net pots of bok choy plant as co-culture. The results that the increase in fish population escalated the productivity of both fish and vegetable in 30 days farming period. The stocking density did not affect fish survival 99 ± 0.82%, 97 ± 1.27%, and 97 ± 0.68%, respectively (p>0.05), but supported a better specific growth rate, namely 3.09 ± 0.30%/day; 3.57 ± 0.23%/day; 4.03 ± 0.04%/day (p<0.05). Interestingly, the smallest coefficient of diversity and lowest feed conversion ratio were obtained at 500 fish/m3, whereas absolute length growth did not differ. Bok choy production increased with fish density, namely 2.82 ± 0.06 kg; 2.88 ± 0.08 kg; 3.17 ± 0.10 kg, respectively (p<0.05). The water quality parameter values were almost identical in all treatments, except for the lowest bacterial abundance gained at stocking density of 500 fish/m3. In conclusion, the aquaponic system can be used to nurseries tilapia seeds at high stocking densities for production efficiency.   Keywords: aquaculture, bok choy, hydroponics, intensification   ABSTRAK   Akuaponik adalah sistem pemeliharaan ikan dan tanaman hidroponik yang memanfaatkan kotoran ikan sebagai nutrisi tanaman. Karena kualitas air dapat dipertahankan pada tingkat optimal untuk ikan dalam sistem akuaponik untuk meningkatkan produktivitas budidaya. Penelitian ini dilakukan mengevaluasi pengaruh peningkatan kepadatan ikan pada tahap pendederan ikan nila merah dalam sistem akuaponik skala kecil. Penelitian dilakukan dengan menggunakan rancangan acak lengkap pada tiga tingkat kepadatan tebar yaitu 250 ekor/m2, 375 ikan/m2, dan ikan nila merah sebanyak 500 ekor/m2 dengan ukuran awal 6,8 ± 0,35 cm, pada masing-masing sistem aquaponik dengan 30 net pot tanaman bok choy. Hasil penelitian menunjukkan peningkatan populasi ikan telah meningkatkan produktivitas ikan dan sayuran dalam masa budidaya 30 hari. Peningkatan padat penebaran tidak berpengaruh terhadap kelangsungan hidup ikan yaitu berturut-turut sebesar 99 ± 0,82%, 97 ± 1,27%, dan 97 ± 0,68% (p>0,05), namun mampu mendukung laju pertumbuhan spesifik yang lebih baik yaitu 3,09 ± 0,30%/hari; 3,57 ± 0,23%/hari; dan 4,03 ± 0,04%/hari (p<0,05). Menariknya, koefisien keanekaragaman terkecil dan rasio konversi pakan terendah diperoleh pada kepadatan 500 ekor/m3, sedangkan pertumbuhan panjang absolut tidak berbeda.
