Abstract

Udang merupakan salah satu komoditas unggulan di dalam bidang budidaya perikanan Indoneia.Salah satu jenis udang yang memiliki nilai ekonomis tinggi dibandingkan dengan jenis udang lainnya adalah Udang Vaname (Litopenaeus vannamei), jenis udang ini sangat banyak diminati untuk dibudidayakan oleh pembudidaya.Hal ini dikarenakan keunggulan yang dimiliki oleh udang vaname membuat para pembudidaya memproduksinya, salah satu keunggulan yang dimiliki adalah memiliki sifat euryhaline yaitu mampu toleransi dan bertahan hidup pada salinitas yang luas.Berdasarkan sifat euryhaline yang dimiliki, udang vaname berpotensi untuk dibudidayakan di media salinitas rendah atau air tawar. Namun jika dibudidayakan di media air tawar maka akan banyak sekali masalah yang akan dihadapi salah satunya adalah tidak terpenuhinya mineral yang dibutuhkan oleh udang tersebut, untuk itu harus menambahkan beberapa jenis mineral yang dibutuhkan seperti kalsium dan fosfor. Tujuan dari penelitian ini adalah untuk mengetahui apa pengaruh pemberian kalsium hidroksida (Ca(OH)2) dan fosfor (P) terhadap pertumbuhan udang vaname yang dipelihara pada media air tawar, dengan dosis yang sesuai kebutuhan dapat memaksimalkan petumbuhan ada udang vaname yang dipelihara. Metode penelitian yang digunakan adalah metode Eksperimental dengan Racangan Acak Lengkap (RAL) yang terdiri dati 5 perlakuan dan 3 kali ulangan, yaitu 80 ppm (Ca(OH)2), 80 ppm (Ca(OH)2) + 40 ppm P, 80 ppm (Ca(OH)2) + 80 ppm P, 80 ppm (Ca(OH)2) + 120 ppm P. penambahan mineral 80 ppm (Ca(OH)2) dan P memberikan pengaruh nyata pada pertumbuhan udang vaname, dengan nilai laju pertumbuhan bobot spesifik 2,70 %/hari, laju pertumbuhan panjang spesifik 6,62 %/hari, tingkat kelangsungan hidup 68,3 %, dan nilai rasio konversi pakan 1,06 terdapat pada P4 (Perlakuan 4).

Abstract

Octopus fishing activities are increasingly being carried out by local fishermen making the variety of catches uncontrollable. It is feared that this diversity of catches will affect the biological condition of the octopus, which will lead to a decrease in the catch of fishermen. This study aims to: (1) determine growth patterns, body shape, age group, condition factors, spawning/maturity fit and catchability in octopus fisheries management, (2) biological dimensions of octopus fisheries management, and (3) identify attributes / lever indicators to increase the index value and sustainability status of the biological dimensions of octopus fisheries management. The results showed that the growth patterns of octopuses landed on Pandanan Beach, North Lombok Regency, were negative allometric with a b value of 2.1600. Meanwhile, octopus body shape is in the less flattened category with a condition factor (K) value of 1.85, with 2 age groups, namely the first age group with a length range of 24 cm - 48 cm and the second age group with a length range of 49 cm - 68 cm. Meanwhile, the number of octopuses worth catching was 238 which weighed > 320 grams, and 2 octopuses that were not yet fit to catch weighed < 320 grams. The sustainability status of octopus management from the biological dimension obtained a value of 52.34% with a fairly sustainable status. The attributes that need priority attention are stock enrichment and range collapse. Changes to these two attributes will affect the increase or decrease in the value of the biological dimension sustainability index.

Abstract

Litopenaeus vannamei is a high-economic fishery commodity that has euryhaline properties, which is tolerant of a wide range of salinity values ??(2 – 40 ppt). The euryhaline of vannamei shrimp are still not well optimized. The purpose of this study was to determine the appropriate dose of ketapang leaf addition to increase mineral solubility in freshwater vannamei shrimp culture medium. The results of this study are expected to be useful as information for vannamei shrimp cultivators in freshwater media about technology for meeting mineral levels in the media so as to maximize production value. This study used a completely randomized design (CRD) method which consisted of 4 treatments and 3 replications. The treatment applied was the addition of ketapang leaves with different doses to increase the solubility of calcium carbonate (CaCO3) in cultivation media, namely A. Ketapang leaves (DK) 0 ppt + CaCO3 50 ppm; B. DK 120 ppm + CaCO3 50 ppm; C. DK 240 ppm + CaCO3 50 ppm; D. DK 360 ppm + CaCO3 50 ppm. The results showed that the appropriate dose of ketapang leaves that could increase mineral solubility in freshwater vannamei shrimp culture media was 360 ppm (treatment D). At this dose, the value of the specific weight growth rate of vannamei shrimp can increase, which is 0.76%/day. Treatment A is a control treatment that gives the lowest value for the specific weight growth value, which is 0.40 %/day.
