The existence of freshwater crayfish in Indonesia is not well known among the community, even some people think that this type of lobster can only be obtained from catches. Freshwater lobster cultivators are always faced with the classic problem of low survival, especially during seed stages. The role of the water bottom substrate for freshwater crayfish is to support stabilizing water quality (temperature, pH, dissolved oxygen and ammonia levels). If the substrate condition of the habitat is not suitable, it can inhibit growth and even death. The purpose of this study is; to find out the effect of different basic substrates can increase the survival and growth of freshwater lobsters. The research method used a Completely Randomized Design (CRD) with 4 treatments 3 replications and 1 control. Each container is stocked with 2-inch lobster seeds with a density of 10 heads / container. The substrate application for each treatment is: A = Control, B = Land, C = Sand Malang, and D = Gravel. Based on the results of the research that has been done, it can be concluded that the administration of different substrates only shows significant differences in the survival variable, with the highest number of 96,67% in treatment C (Malang sand) and the lowest with 66,00% in treatment A (Control). While the variables of absolute weight, absolute length, and daily growth rate did not show significant differences in all treatments.

Abstract This study aimed to examine the effect of Gamal leaves flour supplementation in commercial feed on the growth of Nirwana tilapia (Oreochromis niloticus) fingerlings. The experimental design used was a non-factorial completely randomized design consisting of four treatments and four replications. The treatments studied included commercial feed without supplementation of Gamal leaves flour as a control (P0), commercial feed with supplementation of Gamal leaves flour 10% kg−1 feed (P1), commercial feed with supplementation of Gamal leaves flour 15% kg−1 feed (P2), and commercial feed with supplementation of Gamal leaves flour 20% kg−1 feed (P3). Nirwana tilapia fingerlings were stocked at a density of 1 fish L−1. Nirwana tilapia fingerlings size ranges from 2-3 cm. Nirwana tilapia fingerlings maintenance period lasts for 40 days. The Annova test showed that the treatment gave a significant effect on the weight gain, length gain, daily growth rate, and feed conversion ratio (P < 0,05), but did not give a significant effect on the survival rate of Nirwana tilapia fingerlings (P > 0,05). The best dose to increase the growth of Nirwana tilapia fingerlings was commercial feed with supplementation of Gamal leaves flour 10% kg−1 feed.

Cultivation Environment

The development of catfish culture affects increasing waste in the waters. Aquaculture waste containing high nutrients has the potential to damage the cultivation environment. The Biofloc system in catfish farming can break down NH3 waste into flocks that can be consumed directly by fish. This study aims to analyze the growth and survival rate of catfish in biofloc systems with different C:N ratios. The research design used was a completely randomized design (CRD) with four treatments and three replications. Siamese catfish seeds were maintained in an aquarium container size 40 x 30 x 30 cm for 40 days with treatment media A (maintenance without biofloc), treatment B C:N ratio 15, treatment C C:N ratio 20, and treatment D C:N ratio 25. The results showed that the biofloc system with different C:N ratios had significant effect on the weight growth, daily growth rate, and feed convertion ratio of catfish. The best treatment for growth and viability of catfish is C:N ratio 25.

Peremajaan bibit melalui seleksi dapat dilakukan untuk perbaikan kualitas bibit rumput laut. Penelitian ini bertujuan untuk menentukan performa bibit rumput laut K. alvarezii hasil seleksi varietas Takalar, SIRICA, dan Bali. Desain penelitian adalah rancangan acak lengkap (RAL), dengan empat siklus pemeliharaan sebagai ulangan. Seleksi bibit dilakukan pada ketiga varietas dengan bibit non-seleksi sebagai kontrol internal. Pemeliharaan dilakukan di perairan Laikang, Takalar, Sulawesi Selatan selama empat siklus dengan durasi 30 hari/siklus. Pengukuran laju pertumbuhan harian (LPH), kandungan karagenan, kekuatan gel, dan monitoring kualitas air dilakukan setiap 30 hari. Data yang diperoleh dianalisis menggunakan analisis ragam (ANOVA). Hasil penelitian menunjukkan bahwa seleksi bibit berpengaruh signifikan terhadap LPH rumput laut (P<0,05). Rumput laut hasil seleksi memiliki LPH lebih tinggi, yakni: Bali (4,75 ± 0,04%/hari), SIRICA (4,74 ± 0,06%/hari), dan Takalar (4,62 ± 0,12%/hari) dibandingkan dengan kontrol internal Bali (3,94 ± 0,15%/hari), SIRICA (3,74 ± 0,10%/hari), dan Takalar (3,66 ± 0,32%/hari). Rumput laut hasil seleksi varietas Bali dan SIRICA memiliki kandungan karagenan yang relatif sama yakni (37,27 ± 6,68%) dan (37,08 ± 7,17%). Varietas Takalar memiliki kandungan karagenan yang rendah (31,84 ± 5,32%) namun memiliki kekuatan gel yang paling tinggi (570,03 ± 145,72 g/cm²) dibandingkan varietas Bali (444,39 ± 157,44 g/cm²) dan SIRICA (438,48 ± 72,70 g/cm²).Regeneration by selection method can improve the quality of seaweed seed. This study was aimed to determine the performance of selected seaweed seeds of K. alvarezii from Takalar, SIRICA, and Bali varieties. The experiments were arranged in a completely randomized design with four cycles cultivations as replications. In each variety, a batch of non-selected/regular seeds was cultivated serving as internal control. The seaweed was cultivated in Laikang waters, Takalar Regency, South Sulawesi for 30 days for each cycle. The measurements of daily growth rate (DGR), carrageenan yield, gel strength, and water quality were conducted every 30 days. The collected data were statistically analyzed using ANOVA. The results showed that the selected seeds showed faster growth than that of its respective control (P<0.05). The selected seed of three varieties of K. alvarezii had higher DGR: Bali (4.75 ± 0.04%/day), SIRICA (4.74 ± 0.06%/day), and Takalar (4.62 ± 0.12%/day) than that of control varieties, Bali (3.94 ± 0.15%/day), SIRICA (3.74 ± 0.10%/day), and Takalar (3.66 ± 0.32%/day). The selected seeds of Bali and SIRICA had similar carrageenan content (37.27 ± 6.68%) and (37.08 ± 7.17%), respectively. Takalar had the lowest carrageenan yield (31.84 ± 5.32) but had the highest gel strength (570.03 ± 145.72 g/cm²) compared to Bali (444.39 ± 157.44 g/cm²) and SIRICA (438.48 ± 72.70 g/cm²).

Kappaphycus alvarezii cultivation by the verticulture method has been introduced since 2013. However, scientific studies on some technical aspects are still needed to improve the quality, quantity, and continuity of production and utilization of area in a maximum and productive manner. One of them is the planting distance between seed clumps. The purpose of this study was to determine the optimal planting distance between seed clumps on seaweed verticulture method. Seaweed was cultured using a 10x10 m2 floating raft containing 36 vertical nets of 5x2 m2/net. Seaweed seeds with an initial weight of 50 g were tied to a vertical net with a distance between knot on the verticulture net of 15 cm, 25 cm, and 35 cm. Seaweed cultivation was done for 3 cycles (1 cycle = 45 days) continuously in the cycle of planting season. The experimental units were prepared with Completely Randomized Design (RAL) with 3 replications. The results showed that daily growth rate (DGR) and carrageenan content of seaweed planted with a distance of 15 cm, 25 cm, and 35 cm between clumps were not significantly different (P>0.05). However, it is recommended to apply 25 cm distance between seed clumps in the verticulture method.

Cork fish is one of the commodities from the freshwater fisheries sector which is commonly found in rivers, swamps and swamps that have high economic value and high market demand. The availability of cork fish is still limited to the results of their catch in the wild. And efforts to develop cork fish culture are still small due to slow growth in cork fish and the low response of cork fish to commercially-made feed compared to natural feed. This research is intended to improve the growth of cork fish fed with cinnamon leaf flour (Cinnamomumm burnamani) at different doses.The design used in this study was a completely randomized design (CRD) consisting of 4 treatments with 3 replications. The treatments performed were control (P1), addition of 0.5% cinnamon leaf flour (P2), addition of cinnamon leaf flour 1% (P3), and addition of cinnamon leaf flour 1.5% (P4). The research parameters observed were absolute weight, absolute length, daily growth rate, EP, fat in SR fish body, and cork fish water quality. The results showed that the addition of cinnamon leaf flour at a dose of 1% influenced the growth of absolute weight, absolute length, LPH, and EP. The addition of anis wood leaf flour with a dose of 1.5% can reduce fat content in the body of cork fish.Keywords: Canna striata, Cinnamomum burnamni
