The use of probiotics is certainly one of the solutions in overcoming the problem of increasing seed in fish farming. One of them is the use of probiotic king catfish, in this study tested on catfish, tilapia and goldfish. This research is an experimental study. The design used in this study was a Completely Randomized Design with 4 treatments 3 replications. Data analysis used Statistical Package for the Social Sciences version 15. The results of the analysis of the highest seed survival rate were obtained on Pangasius pangasius (95%), on Oreochromis niloticus (83,33 %), and Cyprinus carpio (80%). The treatment of Rajalele probiotics has a very significant effect (very significant) Fanalysis (23.01) > Ftable 0.01 (7.59) on the graduation of Pangasius pangasius, Oreochromis niloticus, and Cyprinus carpio. The conclusion of this study shows that the survival rate the highest in Pangasius pangasius

Analisou-se o crescimento dos peixes, a composição das espécies e a produtividade de quatro policultivos (P75, P78, P87 e P207), visando melhorar o manejo e a produtividade pesqueira dos pequenos açudes (0,1-5,0ha) do Semi-Árido brasileiro. Simulou-se as condições desses açudes em viveiros com 120 e 5.000 m² de área, sem renovação de água, utilizando moderada quantidade de adubo e fertilizante. A biomassa inicial variou de 75 a 207kg ha-1, sendo formada por: tilápia do Nilo (Oreochromis niloticus), curimatã pacu (Prochilodus argenteus), carpa comum (Cyprinus carpio), tambaqui (Colossoma macropomum) e tucunaré (Cichla ocellaris). Os peixes apresentaram baixo crescimento (< 0,01g g-1 d-1) após 75 dias de criação (P78 e 87). O crescimento do tambaqui, da tilápia e da curimatã foi reduzido após 53 dias (P75). Em moderada biomassa, o crescimento do tambaqui foi inferior ao da carpa e da curimatã (P207). A produtividade da tilápia atingiu 720 kg ha-1ano-1 (P78), sendo reduzida para 220 kg ha-1ano-1 devido ao processo reprodutivo (P75 e P207). A produtividade da carpa de 1.600 kg ha-1ano-1 foi superior a dos outros peixes (P87). A biomassa inicial de 75 kg ha-1 (60:30:4:3:3% de tilápia, tambaqui, carpa, curimatã e tucunaré, respectivamente) otimizou o crescimento e a produtividade dos peixes. A utilização de tilápias monossexadas e o fornecimento da alimentação suplementar ao tambaqui tornam-se imprescindíveis ao policultivo.

Background: Lake Diatas is one of the important lake which is influenced by agricultural activities around the lake, and chlorpyrifos is widely used as a pesticide in this area. This study aimed to analyze the damage of the gill tissue of Oreochromis niloticus L. and Cyprinus carpio L. as two freshwater fish, which are mostly caught to be consumed by the residents in Lake Diatas, Indonesia, that were exposed to chlorpyrifos. Methods: Acclimatization was performed for 14 days and continued with toxicity test for 30 days. Chlorpyrifos exposure was tested at various concentrations. Fish gill tissue was observed microscopically in 10, 20, and 30 days of exposure, and damages were scored based on the level of gill tissue damage. Results: It was revealed that O. niloticus L. experienced edema, proximal basal hyperplasia, fusion, hyperplasia in all secondary lamellae, and necrosis at the higher exposure concentration. While C. carpio L. experienced fusion, hyperplasia, clubbing, necrosis, and obvious degradation of gill tissue of fish after 30 days of exposure to chlorpyrifos. There was a significant difference in the damage of fish gill tissue between each variation treatment (P<0.05). Conclusion: According to the results, the higher the concentration of chlorpyrifos and the longer the exposure time, the higher the level of damage in gill tissue.

Informasi dasar mengenai potensi reproduksi ikan dapat diperoleh dari tinjauan fenomena perkembangan gonad, untuk memprediksi proses reproduksi sampai ikan memijah dan menghasilkan benih sebagai baby fish. Tujuan penelitian adalah mengetahui fekunditas, diameter telur, gonado somato index (GSI) dan kelangsungan hidup larva. Metode yang digunakan survey, pengambilan sampel puposive random. Materi penelitian adalah induk Cyprinus carpio, Barbonymus gonionatus, Osteochillus vittatus, Oreochromis niloticus dan Clarias gariepinus, sebanyak 3 pasang/species. Variabel  adalah fekunditas, diameter telur, gonado somato index (GSI) dan kelangsungan hidup larva. Parameter yang diukur berat ikan, berat gonad, jumlah telur sebagian, ukuran telur dan jumlah larva hidup. Metode penelitian survey, pengambilan data adalah puposive  random dan data dianalisis dengan Anova. Hasil penelitian  diperoleh bahwa  fekunditas dan GSI  pada 5 species ikan menunjukkan perbedaan (P<0,05), B. gonionotus  memiliki fekunditas tertinggi rata-rata 182.320 butir dan O. vittatus memiliki nilai GSI tertinggi  35,13%. Diameter telur  berbeda-beda pada semua  spesies,  B. Gonionotus memiliki diameter terkecil yaitu kisaran 0,486 – 0,729 mm, sedangkan diameter terbesar pada ikan C. carpio rata-rata  1,170 mm. Larva  O. Niloticus menghasilkan prosentase kelangsungan hidup terbaik sebesar 97%, O. vittatus 93%, C. carpio 77,2%, C. gariepinus 51,6%, B. gonionotus 31%  dan uji Least Significant Difference  larva O. niloticus dan O. vittatus  memiliki kelangsungan hidup sama baik,  berpotensi dikembangkan sebagai baby fish. O. vittatus memiliki peluang besar dikembangkan menjadi baby fish sampai ukuran 5 g/ekor dengan fekunditas rata-rata 16.250 butir.
