Sea cucumbers include important components in the food chain because of its role as the sediment feeder and suspended feeder. It is therefore necessary that adequate information that can be used for sea cucumber management in a sustainable manner. One method used is to use geographic information system (GIS). This method can be used to make it easier to know the location of its spreading, so the development of sea cucumber <em>(Holothuria scabra)</em> in aquaculture&nbsp; can be achieved optimally. The purpose of this study was to analyze the suitability of the sea cucumber cultivation areas using GIS applications were presented in map form suitability sea cucumber cultivation area <em>(H</em><em>. scabra)</em> in West Lombok Waters. This study was conducted on 17th October - 27th November 2016 at Gili Asahan, Gili Layar, and Gili Gede in West Sekotong, Lombok, West Nusa Tenggara. Data was collected by survey methods, such as primary and secondary data directly related to the life of sea cucumbers. Based on chemical parameter the result of this research in West Lombok were pH&nbsp; 6,82 – 7,50, salinity 32 – 34 ppt and DO 6,19 – 6,52 mg/L.

Microalgae culture need a supporting factors to help a growing process. That factors like a temperature, light intensity, CO<sub>2, </sub>and nutrient. The problem that often arise in microalgae culture like an algae population whose that growth are unstable cause uantity of <em>Chaetoceros </em>that not same in every culture period. This is due to supporting factors less than optimal like less of nutrient of growth media. Vannamei shrimp contains 77% nitrogen and 85% phosphor that can used to microalgae growth. The research purpose to assess utilization waste vanamei shrimp farming (<em>Litopenaeus vanamei</em>) as a media cultur <em>Chaetoceros amami</em>. This research was done in microalgae PT. Central Proteina Prima Lampung Selatan Kalianda. The design of the research is completed random design that consists three treatments and three repetitions, design A (control) used walne fertilizer, design B used 25% shrimp vannamei waste and design C used 50% vannamei shrimp. Result of Duncan&nbsp; test (p&gt;0,05) showed that peak phase during culture <em>Chaetoceros amami</em> in media of water vannamei shrimp farming is different, the conclusion of this research is waste vannamei shrimp farming as many (50/50) waste could replace synthetic fertilizer (walne) as media <em>Chaetoceros amami</em> culture in laboratory scale culture.</p> Nanda Febrinawati, Berta Putri, Siti Hudaidah Copyright (c) 2020 Jurnal Perikanan Unram http://jperairan.unram.ac.id/index.php/JP/article/view/199 Sun, 31 May 2020 12:01:55 +0800 THE EFFECT OF SAP CONCENTRATION OF ARENG PALM (Arenga pinnata) ON SURVIVAL AND GROWTH OF MILKFISH (Chanos chanos Forskal) LARVAE http://jperairan.unram.ac.id/index.php/JP/article/view/177 <p><em>The aim</em><em>s</em>&nbsp;of the&nbsp;<em>study</em>&nbsp;<em>wer</em><em>e</em><em> to determine the effect of sap concentration of areng palm (Arenga pinnata) on the survival and growth of milkfish larvae (Chanos chanos Forskal) and </em><em>to </em><em>get the best </em><em>sap </em><em>concentration for the survival and growth of milkfish larvae. The study used an experimental method </em><em>and the </em><em>experimental units randomized using a Completely Randomized Design (CRD) consisting of four treatments and each treatment was repeated three times. The treatments tested were the addition of areng palm sap into larval rearing media with a concentration of 2.4 ml/l, 4.8 ml/l and 7.2 ml/l. The treatment without adding </em><em>areng palm </em><em>sap </em><em>was </em><em>used as a control. This research was conducted at the Marine Aquaculture Development Center, Sekotong, West Lombok Regency, West Nusa Tenggara Province for 30 days starting from 31 August 2019 - 24 September 2019. The results showed that the addition of areng palm sap into the milkfish larvae rearing media had a significant effect in the survival and growth of milkfish larvae (F-value &gt; Fcrit 5%). Larval survival, daily specific growth rate of body weight and absolute growth of the larval total length were obtained in the treatment of 7.2 ml/l with the value of each parameter is 67.85%, 15.25% per day and 9.05 mm for 18 days of maintenance. The three parameters in this concentration treatment did not show any significant difference with the treatment of 4.8 ml/l and 2.4 ml/l of areng palm sap concentration but were significantly different </em><em>to</em><em> the control treatment (0 ml/l). It is recommended to apply the addition of areng palm sap in the maintenance media of milkfish larvae with a maximum concentration of 7.2 ml/l. Further research needs to be done about increasing the concentration of areng palm sap above 7.2 ml/l in the media of milkfish larvae maintenance to get the optimum concentration for the survival and growth of milkfish larvae.</em></p> Diaz Asa Gusmi, Nanda Diniarti, Alis Mukhlis Copyright (c) 2020 Jurnal Perikanan Unram http://jperairan.unram.ac.id/index.php/JP/article/view/177 Sat, 30 May 2020 21:47:35 +0800 GIVING Spirulina platensis MEAL IN FEED TO THE BRIGHTNESS OF CLOWN FISH (Amphiprionocellaris) http://jperairan.unram.ac.id/index.php/JP/article/view/187 <p>This study aims to determine the exact dosage of S. platensis flour in feed to improve the color quality of clown fish. The method used was an experimental method using a Completely Randomized Design (CRD) consisting of 5 treatments and 3 replications, P0 (control), P1 (S. platensis meal 1%), P2 (S. platensis meal 3%), P3 (S. platensis meal 5%), and P4 (S. platensis meal 7%). The results showed that there was no significant effect on the level of color brightness and survival rate, but had a significant effect on the growth of absolute weight, absolute length growth, specific weight growth rate, and specific length growth rate. It is known that P2 (S. platensis meal 3%) is the highest treatment at the level of color brightness (181.6%), absolute weight growth with 0.26 g and the best treatment at a specific weight growth rate with 1.44 g. Whereas P4 (S. platensis meal 7%) is the best treatment at absolute length growth with 0.62 cm and the best treatment at the specific length growth rate with 0.73 cm. Based on the results of the study, it was concluded that the addition of Spirulina platensis meal to feed at a dose of 3% (Treatment 2) is the doses to increase the brightness of the clown fish.</p> Hadijah, Muhammad Junaidi, Dewi Putri Lestari Copyright (c) 2020 Jurnal Perikanan Unram http://jperairan.unram.ac.id/index.php/JP/article/view/187 Sat, 30 May 2020 21:51:51 +0800 IMPROVEMENT RATIO OF MALE TILAPIA USING 17α-METHYLTESTOSTERONE THROUGH FEEDING http://jperairan.unram.ac.id/index.php/JP/article/view/200 <p>The success of masculinization in tilapia shows that the use of the hormone 17α-methyltestosterone (MT) is more effective than temperature. However, the use of hormones by feeding through food has not shown better results compared to soaking the larvae. Even though the application through feeding is easier to do. Therefore, in this study, the administration of hormones through feed will be carried out with the experimental time of feeding exceeding the highest critical time, which is for 30 and 50 days. D'Cotta et al. (2007) and Ijiri et al. (2008) states that the critical time for sex change in tilapia is 9-15 days after fertilization/day post-fertilization/dpf. The objective to be achieved in this study is to obtain the optimal duration of 17α Metiltestosterone hormones through a feed to produce male tilapia mono sex. Treatment using 17α-methyltestosterone at a dose of 60 mg/kg with a treatment duration of feeding 0, 30, and 50 days. The influence of the length of time for feeding containing hormones was tested using the ANOVA test at 95% confidence intervals. The results obtained showed that the use of 17α-methyltestosterone in reversal sex with a dose of 60 mg/kg of feed with a duration of 0, 30, and 50 days showed a difference in the number of male tilapia produced. However, there was no noticeable difference in the male sex ratio at 30 and 50 days of feeding. So it can be concluded that feeding 17α-methyltestosterone hormone through the feed for 30-50 days after hatching can increase the male sex ratio in tilapia by more than 80%.</p> Epro Barades, Dwi Puji Hartono, Pindo Witoko, Rahmadi Aziz Copyright (c) 2020 Jurnal Perikanan Unram http://jperairan.unram.ac.id/index.php/JP/article/view/200 Sun, 31 May 2020 12:05:41 +0800 PROFILE OF BLOOD OF SEABASS INFECTED BY Vibrio sp.
