This study used a Completely Randomized Design (RAL) consisting of 4 treatments using with different seed weight. The treatment were P1: 50 gr, P2:75 gr, P3:100 gr, P4:125 gr. Treatments ware repeated 4 times (4 rafts). Data of obtained research variables od, be tabulated using excel microsof and &nbsp;be analyzed using analysis of variance and be continued tested by using Least Significant Difference (LSD) test. The highest weight gain result was obtained at weight of 125 gr and the highest growth rate at 50 gr, where in each of these treatments had an effect (p &lt;0.05) seed weight on growth. This&nbsp; related to the competition of each individual seaweed in absorbing sunlight for photosynthesis. Weight of seed is one of the technical factors that can affect the growth of seaweed. &nbsp;Density in each seaweed bonds need to be so that it can cause seaweed fall.</p> Nunik C9okrowati Copyright (c) 2019 Jurnal Perikanan Unram http://jperairan.unram.ac.id/index.php/JP/article/view/145 Wed, 08 May 2019 00:00:00 +0800 ANALISA PERTUMBUHAN IKAN LELE (Clarias sp.) HASIL SILANGAN SANGKURIANG, MASAMO DAN PHYTON http://jperairan.unram.ac.id/index.php/JP/article/view/143 <p>Di NTB budidaya lele dibagi menjadi dua potensi yaitu potensi perkolaman dan perairan umum. Luas perkolaman sekitar 8.960 ha dan perairan umum 33.750 ha, sehingga ikan lele menjadi salah satu komuditas andalan di NTB. Salah satu penyebab kegagalan didalam budidaya ikan lele adalah rendahnya kualitas benih yang beredar di masyarakat. Rendahnya kualitas benih ini merupakan salah satu akibat dari resiko <em>inbreeding</em> yang dapat menurunkan kualitas benih baik dari pertumbuhan, meningkatkan angka FCR maupun menurunkan ketahanan tubuh benih dari serangan penyakit dan fluktuasi lingkungan. Penelitian ini bertujuan mengetahui apakah pada hasil persilangan &nbsp;terdapat laju pertumbuhan yang lebih baik dari indukan yang tidak disilangkan. Hasil persilangan diukur dalam satuan berat (gram) dan panjang (cm) ikan. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Kelompok (RAK) dengan ulangan sebanyak 3 kali. Berdasarkan hasil penelitian diperoleh bahwa hasil silangan ♀Sangkuriang &gt;&lt; ♂Masamo mempunyai nilai &nbsp;pertumbuhan tertinggi dengan berat 302,0<sup>a</sup> g/ekor dan panjang 31,2<sup>a</sup> cm/ekor &nbsp;serta <em>Feed Conversion Ratio</em> (FCR) paling baik yaitu 0,9 yang berbeda nyata <em>(p&lt;0,05)</em> &nbsp;dengan hasil silangan</p> <p>Masamo &gt;&lt; Sangkuriang, Phyton &gt;&lt; Masamo, Masamo &gt;&lt; Phyton, Phyton &gt;&lt; Sangkuriang, Sangkuriang &gt;&lt; Phyton, maupun indukan yang tidak disilangkan yaitu Sangkuriang &gt;&lt; Sangkuriang, Masamo &gt;&lt; Masamo dan Phyton &gt;&lt; Phyton.</p> <p>&nbsp;</p> <p>Keyword : Ikan Lele, Laju Pertumbuhan, Persilangan</p> Ni Kadek Puji Astuti Copyright (c) 2019 Jurnal Perikanan Unram http://jperairan.unram.ac.id/index.php/JP/article/view/143 Wed, 08 May 2019 00:00:00 +0800 the the effect on the combnatio tofu and bran fermentation on the growth of the population Daphnia magna http://jperairan.unram.ac.id/index.php/JP/article/view/138 <p>Daphnia magna is an animal Crustacea which is often referred to as small-sized water lice that live in freshwater and is one of the natural feeds for aquatic larvae which are easily digested, their size is in accordance with mouth openings, has high nutrient content, contains essential amino acids which high and can be cultivated in bulk. Tofu pulp and bran organic fermented with probiotic bacteria are expected to increase the efficiency of feed utilization and growth of Daphnia magna.

One of the most important natural feeds in aquatic ecosystems is phytoplankton which is the main producer that contributes the most to the total primary water products. One type of phytoplankton commonly cultivated is <em>Chaetoceros calcitrans</em>. Nutrient enrichment in growing media can be done through the provision of several types of fertilizers. One type of fertilizer commonly used in phytoplankton cultivation is KW21 fertilizer. Silicate is an essential macro nutrient needed for microalgae growth in the formation of its cell walls to have high resistance to environmental stresses such as extreme conditions. One type of fertilizer that contains silicates which is a fertilizer for local products (Lombok) namely Nutrisil. The aim of the study was to determine the effect of Nutrisil fertilizer and KW21+S on growth and double time of <em>Chaetoceros calcitrans</em>. This study uses a completely randomized design with treatment A= concentration of Nutrisil 1,0 mL/L, B= concentration of Nutrisil 0,75 mL/L, C = concentration of &nbsp;Nutrisil 0,5 mL/L, D = concentration of &nbsp;Nutrisil 0,25 mL/L dan E = concentration of &nbsp;KW21 1 mL/L + Si 1 mg/L. &nbsp;.The data obtained were analyzed using Anova with level 5%.

Cultivation http://jperairan.unram.ac.id/index.php/JP/article/view/136 <p>The use of high stocking densities encourages farmers to use protein-made feed to meet feed requirements. As a result, there is a decrease in water quality of cultivation which is triggered by the high remaining food and the rest of the metabolism of fish. Iswandi (2016) explained that the inedible feces and feed produced by products in the form of phosphate (PO4), ammonia (NH3), nitrite (NO2), and nitrate (NO3). An effort that can be done to reduce the content of ammonia is to convert these materials by photoautrophic through algae or plants. One of the algae that is able to utilize these ingredients is Spirulina sp. Therefore, this study aims to determine the effect of the use of waste water in catfish farming as a growth medium for Spirulina sp. This research began on the 1st to 12th of September 2018 at the Batu Kumbung Aquaculture Center, Lingsar District, West Lombok. The treatments used were P1 (fresh water + Spirulina sp. + Fertilizer), P2 (Waste water from catfish pond + Spirulina sp.) And P3 (Waste water from catfish pond + Spirulina sp. + Fertilizer. The results obtained, the treatment of P3 with a combination of fertilizers with wastewater catfish pond is the best treatment by producing a density of 25,400 synosoid / ml, Biomass of 0,174 grams / ml, and Specific Growth Rate of 0.19 sinosoid / ml / day and has the fastest doubling time 3,554 days between treatments P1 and P2.</p> Panca Aria Lesmana Panca Lesmana Copyright (c) 2019 Jurnal Perikanan Unram http://jperairan.unram.ac.id/index.php/JP/article/view/136 Wed, 08 May 2019 00:00:00 +0800 PERFORMA REPRODUKSI IKAN BETOK (Anabas testudineus) BETINA DENGAN PEMBERIAN PAKAN BUATAN BERBAHAN BAKU TEPUNG KEONG MAS (Pomacea canaliculata) http://jperairan.unram.ac.id/index.php/JP/article/view/129 <p><strong><em>Abstract:</em></strong> <em>Climbing perch (</em><em>Anabas testudineus</em><em>) is one of the potential local fish species to be cultivated. The purpose of this study was to learn and evaluate the effect of feeding made from golden snail (Pomacea canaliculata) on the level of gonad maturity. The study was conducted in July - August 2018. The climbing perch (A. testudineus) originated from natural catchments in the rice fields of Rias village, Toboali Subdistrict, South Bangka Regency.
