<p>Seurukan fish (<em>Osteochilus vittatus</em>) has many advantages, besides the fish also has disadvantages which are the slow growth, so the temperature shock of triploidization technique was expected to solve the problem.   The objective of the present study was to obtain an effective temperature to increase of triploidization success of <em>seurukan</em> fish (<em>Osteochilus vittatus</em>). The experimental method and completely randomized design model were used in this study. Five levels of temperature shocks at three replicates were tasted: 4℃ (cold), 6℃ (cold), 28℃ (normal), 35℃ (heat) and 37℃ (heat). The sperms and eggs were fertilized in the plastic jar then a total 100 of fertilized eggs (zygotes) were taken randomly 3 minutes after fertilization and soaked in respective temperature for 90 seconds, and then incubated in incubation jars at the water temperature of 28-29℃. The results showed that the temperature shock gave the significant effect on the hatching and the success of triploidization success (P˂0.05), but did not give the significant effect the fertility and survival rates (P&gt;0.05). The triploid fish can be achieved using cold and heat shock, but the higher triploid fish was recorded at 37℃ was the best temperature recommended for triploidization of <em>Seurukan</em> fish.</p>

Some research found that p rotein adequacy from snack for elementary school children are still lacked. Snacks availability at schools have an important role to fulfi ll  protein requirement  for students. The purpose of this research was to analyze the effect of  catfi sh (Clarias gariepinus) and Isolated Soy Protein (ISP) addition on    acceptance level and p rotein content of c ilok (snack). Research methods used for formula development was experimental research with completely randomized design. Repetition was performed four times on fi ve treatments (one control and four modifi cations, those are F1 was added ISP, F2 was added c atfi sh, F3 was added c atfi sh fl our, and F4 was added c atfi sh and ISP). Assessment of a  cceptance used hedonic test. Variable in this research was a  cceptance level (color, aroma, texture, and fl avor) and p rotein content. Hedonic test was performed to 71 students. The difference of a  cceptance (color, aroma, texture, and fl avor) between 5 formulas was tested used Cochran’s Q; the difference within formula then analyzed by Mc Nemar test. Hedonic test result showed that panelists preferred F0. F4 had highest p rotein level based on DKBM and laboratory analysis found  protein level (9.4 g/ 100 g) higher than recommended value. Cochran’s Q test showed signifi cant difference a  cceptance on color (p = 0.002) and taste (p = 0.047). Mc Nemar test showed the difference within formula on the color was F0 with F3, F1 with F3, and F2 with F3, while difference fl avor formula found in F0 with F3. This research concluded that F4 had the highest p rotein level but the a  cceptance was still low, it is recommended to modify F4 so that it become more acceptable but did not change the  protein content.

The effect of baker’s yeast as immunostimulant on innate immunity of carp (Cyprinus carpio L) had been investigated.  Fish was gathered from Freshwater Aquaculture Board (BBAT) Tatelu, Province of North Sulawesi.  The fish were acclimatized for a week in 15 aquariua with a density of 25 fish/aquarium. After acclimatization the fish were fed pellet supplemented with baker’s yeast as immunostimulant at 0, 5, 10, 15 and 20 g / kg of feed for four weeks as much as 5%/body weight of fish/day with the frequency of feeding twice a day at 08.00 am and 16.00 pm . This study used Completely Randomized Design (RAL) with five treatments and each treatment had three replications. Immune parameters consisting of total leucocytes and phagocytosis activity were measured in the last week. After  four weeks of feeding, the total leukocytes from the carp fed with the addition of baker’s yeast 10 g / kg of feed were significantly increased compared with the fish not being fed with the addition of bread yeast (p <0.01). Phagocytic activity of phagocyte cells from carp also increased significantly in fish fed pellet with the addition of 5 g of baker’s yeast / kg of feed (p = 0.01). In conclusion, the addition of baker’s yeast as immunostimulant in the diet at 5-10 g/kg of pellet can increase the nonspecific immune response of carp. Keywords:  baker’s yeast, carp, nonspesific immune response, total leucocytes, phagocytosis activity

This research aims to understand the effect of the different natural anesthesia on the survival rate of sangkuriang catfish juvenile which was transported using closed wet system fish transportation. We discussed selected natural anesthesia for effectiveness, induction times and recovery times in the application of anesthesia for transportation. The benefits of this research were as a reference to choose the best natural anesthesia for catfish juvenile transportation. This research used the experimental method on Completely Randomized Design (CRD) with 4 treatments (clove oil, nutmeg oil, lemongrass oil, and control) with 3 replications. Measured parameters were survival rate after fish transportation, survival rate after aquaculture for 7 days, induction times, recovery times,and water quality such as temperature, dissolved oxygen (DO), pH, and ammonia. The result was clove oil had high survival rate after fish transportation and cultivated for 7 days which is 98,67% and 87,33%. This treatment had quicker time for induction of catfish juvenile than other treatments which was 12.59 minutes although recovery time (10.34) minute was assumed lower than other treatments.
