Tanaman wori merupakan salah satu tanaman kelompok fabaceace yang tumbuh melimpah di Sangihe dan sangat potensial digunakan sebagai salah satu sumber pakan ikan. Kadar protein daun wori adalah 25,53% sehingga berpotensi menjadi protein nabati bagi ikan. Kendala utama yang ditemui ketika memanfaatkan daun tanaman wori adalah kandungan karbohidrat yang tinggi yaitu 48,51% sehingga dapat mempengaruhi proses pencernaan ikan, penyerapan nutrisi yang berujung pada rendahnya pertumbuhan ikan. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh tepung daun wori femerntasi terhadap laju pertumbuhan spesifik dan sintasan hidup ikan nila. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL). Perlakuan yang dilakukan terdiri dari tiga perlakuan dan tiga kali ulangan yaitu kadar tepung daun wori tanpa fermentasi A (kontrol) 10%, kemudian B tepung daun wori fermentasi (10%), dan C tepung daun wori fermentasi (20%). Laju pertumbuhan spesifik dan efisiensi pakan diuji menggunakan ANOVA sedangkan sintasan hidup akan dianalisis secara deskriptif. Hasil penelitian ini menunjukan bahwa penambahan tepung wori fermenasi dalam pakan dapat meningkatkan nilai laju pertumbuhan spesfik ikan nila dan efisiensi pemanfaatan pakan dengan nilai tertinggi pada perlakuan C yaitu SGR 1,94%/hari. Sementara itu, untuk semua perlakuan nilai sintasan hidup sebesar 100%.   The wori plant is one of the plants of the fabaceace group that grows abundantly in Sangihe and has potential to be used as a source of fish feed. The protein content of wori leaves is 25.53%, so it has the potential to become vegetable protein for fish. The main obstacle encountered when utilizing wori plant leaves is the high carbohydrate content of 48.51% so that it can affect the digestion process of fish, nutrient absorption which lead to low fish growth. The purpose of this study was to determine the effect of wori femerntation leaf meal on the specific growth rate and survival of tilapia. The experimental design used was a completely randomized design (CRD). The treatments consisted of three treatments and three replications, namely the content of fermented wori leaf powder, A (control) 10%, then B fermented wori leaf powder (10%), and C fermented wori leaf powder (20%). Specific growth rate and feed efficiency were tested using ANOVA, while survival rate was analyzed descriptively. The results of this study indicate that the addition of fermented wori powder in the feed can increase the value of the specific growth rate of tilapia and feed utilization efficiency with the highest value in treatment C, namely SGR 1.94% / day. Meanwhile, for all treatments the survival rate was 100%.

Tilapia (Oreochromis niloticus) is populer as resistant fish to environmental changes. Cultivating fish with a high stocking density can cause a decrease in water quality. It has an impact on susceptibility to disease due to decreased water quality. Immunostimulants from Phyto-pharmacy are needed to improve the non-specific immune system of fish from natural ingredients. Bay leaves (Syzigium polyanthum) have the potential to be used as an immunostimulant in fish. This study aimed to evaluate the extract of Salam leaves fortified in feed against the blood profile of Tilapia. The research was carried out in April - May 2018 using a completely randomized design (CRD) with 4 treatments and 3 replications. Salam leaf extract through feed affects the increase of leucocytes and blood erythrocytes of tilapia but does not affect hemoglobin levels and hematocrit levels. Doses of 2x10-2 g mL-1 increased fish blood leukocytes on day 21st to be the best treatment in this study.

High Feed

The success of catfish farming (Clarias sp.) is influenced by feed and water quality. The low feed utilization results in high feed production costs. Alternative use of feed using the enzyme papain and probiotics, the papain enzyme is able to hydrolyze proteins into peptides to increase the utilization of protein in feed by the body. In addition, increased digestibility is done by the addition of probiotic bacteria such as Lactobacillus sp., Saccharomyses sp., Azotobacter sp., Streptomyces sp., Aspergillus sp., Trichoderma sp. into food that can increase feed digestibility and nutrient absorption. Water quality is one of the factors that caused a low survival rate of fish. Biofloc technology utilizes microbial activity that can convert organic waste intensively to form a flock that used by fish as a food source. This study aims to examine the effect of papain and probiotics enzyme addition in feed towards the growth, efficiency of feed utilization and survival rate of catfish using biofloc techniques. The research used a Completely Randomized Design (CRD) by five treatments using biofloc maintenance media and five treatments using non-biofloc, each repeated three times. This research used catfish with a density of 1 head /L kept for 4 weeks as a test animal, treatment P0 (test feed 0.0 gr / kg papain enzyme and 0 mL probiotics), P1 (test feed 0.25 gr / kg papain enzyme and 1 mL probiotic), P2 (Test feed 0.25 gr / kg papain enzyme and 2 mL probiotics), P3 (Test feed 0.5 gr / kg papain enzyme and 1 mL probiotic), P4 (Test feed 0.5 gr / kg of papain enzyme and 2 mL probiotics). The results showed that the addition of the papain and probiotics enzyme in feed with the best dosage was P2 with biofloc maintenance media that gave a real effect (P <0.05) on the efficiency of feed utilization and survival, but had no significant effect (P> 0.05) on growth of catfish (Clarias sp.). Water quality in the maintenance media is in a decent range for the maintenance of test fish.
