Abstract

Udang vaname (Litopenaeus vannamei) Stadia Post Larva sangat rentan terhadap Pertumbuhan dan Sintasan Sehingga Pakan Biasa tidak cukup untuk memenuhi Kelangsungan Hidup udang vaname. Dengan Keadaan tersebut kita dapat memanfaatkan Pengaplikasian Probiotik Em4 dan Bacillus sp terhadap pakan buatan dengan Tujuan Untuk Mengetahui Pertumbuhan dan Kelangsungan Hidup udang vaname. Penelitian ini Bertujuan untuk mengetahui Keberhasilan Pemberian Probiotik em4 danBacillus sp pada Pakan Buatan dan melakukan perbandingan dengan pemberian pakan pada udang tanpa pengaplikasian Probiotik. yang dilakukan adalah Persiapan Media, Pembuatan dan Penambahan Bacillus sp pada pakan Udang, Penebaran benur, pemeliharaan udang, pengamatan sampling, pengamatan kualitas air, dan Pemanenan. penebaran benur sebanyak 50 ekor dalam 1 Akuarium stadia post larva 7 udang vaname dan pemberian Probiotik Bacillus sp dengan Dosis 20 mL/kg pakan dan dosis em4 dengan dosis 15 ml/kg pakan. Data Survival Rate (SR) Akuarium Pemberian Probiotik Bacillus sp pada pakan buatan Udang Vaname yaitu 80%, Berat rata-rata 2,96 gram, Pertumbuhan Panjang Udang rata-rata 10,4. kemudian data Survival Rate (SR) Akuarium terkontrol yaitu 60%, berat rata-rata 2,77 gram, pertumbuhan panjang rata-rata 7,39 cm.  kemudian untuk hasil dengan penambahan probiotik em4 data Survival Rate (SR) Akuarium Pemberian Probiotik em4 pada pakan buatan Udang Vaname yaitu 64 %, Berat rata-rata 3,11 gram, Pertumbuhan Panjang Udang rata-rata 9,07 cm.

Abstract

The availability of broodstock in vannamei shrimp cultivation, especially in hatchery activities, is generally the main requirement. The lack of availability of good quality broodstock is an obstacle in shrimp hatchery activities. One of them is a decrease in egg hatchability which can affect the number and quality of Nauplius produced. Maturation is the initial stage in the process of prospective parent vannamei shrimp becoming mature gonads. Apart from that, the aim of maturation is to maximize growth into adult parent shrimp so that prospective parent vannamei shrimp are ready for spawning. Data collection through observation, documentation, and direct participation in the field in parent maturation activities. The average fecundity produced by each parent during the research ranged from 150-250 thousand eggs. Meanwhile the Hatching Rate was 78.60-79.91%, in December it was 68.37-72.71%. Fertilization Rate (FR) 60-75, Survival of vannamei shrimp in November 91.5%. December 89.5%. The results of water quality measurements, the temperature in the broodstock maturation rearing tank at PT Bibit Unggul Kalianda is around 28-30 oC and the salinity is around 30 ppt.

Abstract

The Marble Molly fish (Poecilia sphenops) and the Sunkist Balloon Molly (Poecilia sphenops) are one of the fish that are popular in Indonesia. It is hoped that crossing sunkist mollies and marble mollies will produce unique colors and new patterns, with diverse and unique colors so that public interest will once again be high in keeping ornamental fish, especially mollies. The methods used start from preparing tools and materials, preparing spawning tanks and larval rearing tanks, selecting mature gonad male and female parents with the characteristics of the male having a gonopodium on his stomach while the female does not have it with the age of the male and female being at least 4 months before they can be spawned. The cross is carried out with a ratio of males and females, namely 5 males and 10 females in each spawning tank, there are 6 spawning tanks with 3 tanks representing the cross between a marbled male and a Sunkis female and another 3 tanks with a Sunkist male and a marbled female, then the best data is taken from the 2nd following treatment. The results obtained were the emergence of 3 color variations and 5 pattern variations with unique and varied colors and patterns.
