Abstract

The aims of this study is to determine the number and distribution of the chromosomes of three Nile tilapia (Oreochromis niloticus) varieties as basic information in the process of identifying the characteristics of varieties in tilapia. This research was conducted in August-October 2016, at the Unair Banyuwangi PSDKU laboratory. The research procedures included rearing of test fish, immersion of test fish with colchicine solution and tissue preservation, preparation of preparations and staining, and observation. Based on the results of the study, it was found that each variety of tilapia (black, red, and white) showed a difference in the spread of chromosomes, while the number of chromosomes was the same, namely 44 pieces.

Abstract

The study aimed to determine the type of culture container for increasing the cell density of Nitzschia and producing the hightly cell biomass. The stages of this study were sterilization of containers and media, making diatom fertilizers and agar media, culture of Nitzschia in agar medium, culture of Nitzschia in test tube, and culture of Nitzschia in glass and plastic containers. The result showed that the cell density of Nitzschia cultured in the glass container was higher than plastic containers. Further study was needed to determine the nutrient composition of Nitzschia that culture in glass containers.Keyword : Nitzschia culture, Laboratory scale, Glass, Plastic container.

Abstract

Pacific white shrimp (Litopenaeus vannamei) is one of the leading fisheries commodities that have important economic value and are in great demand by consumers in the market. Pacific white shrimp has several advantages, namely rapid growth, able to adapt to a high range of salinity, and can be cultured with a super intensive system, but in recent years the total shrimp production in Indonesia has decreased. In 2012 the total shrimp production decreased from 1.900 tons to 1.025 tons, the virus is thought to be a pathogen that triggers disease in shrimp and causes high mortality. The type of virus that causes disease in pacific white shrimp cultivation is Taura Syndrome Virus (TSV), Infectious Myonecrosis Virus (IMNV), and White Spot Syndrome Virus (WSSV). The purpose of this study is to detect viruses that infected and determine the prevalence of viruses that attack pacific white shrimp. The research was conducted in December 2018 to January 2019 at Fish Quarantine Center, Quality Control and Security of Fishery Product Surabaya I. The material used in the study was 37 post larval samples. Samples extracted using Silica Extraction Kit, then detected molecularly using PCR (Polymerase Chain Reaction). This research was observational, then the data obtained were analyzed descriptively. The results showed that there were 3 positive samples of IMNV and 2 positive samples of WSSV with prevalence values of 8.10% and 5.40%. High and low prevalence values are influenced by the level of virus spread and inappropriate environmental conditions. Keywords : Pacific white shrimp, PCR (Polymerase Chain Reaction), prevalence, virus.

Abstract

The need for gouramy (Osphronemus gouramy) continues to increase, this can be seen from the gouramy trade which has begun at the egg stage, so research is needed that affects the number of eggs (fecundity) of the gouramy parent. In this study aims to determine the relationship between age and fecundity of gouramy. The research method used is comparative descriptive. Main gouramy fish is divided into 3 based on their age, pond A is 2.5 years old, pond B is 4 years old and pond C is 8 years old. Observations were made by taking eggs from the nest in each pond then counted manually. The observations showed that the parent who was 4 years old had the highest level of fecundity.Keyword : Age, Fecundity, Osphoronemus gourami

Abstract

Betta fish is a fish that has a high economic value, Market demand always increasing. However, to get high Quality betta fish, efforts are still needed by importing from Singapore and Thailand so that a sustainable betta fish hatchery business is needed. To develop this betta fish hatchery business, the first thing that must be considered is the value of fecundity. Fecundity plays an important role in supporting the success of fish growth. This study aims to determine the relationship between the length and weight of betta fish broodstock to the value of fecundity as an effort to develop in the field of aquaculture, especially at the hatchery stage. The method used in this research is Descriptive method which is then analyzed using linear regression, namely the relationship between length and weight on the fecundity of betta fish. The data is presented in the form of tables and graphs which are then analyzed descriptively to draw conclusions from the resulting data. In this study, 30 brood betta fish were used with body weights ranging from 1.39 to 1.73gr and lengths of 4.5 to 5.2cm and the resulting fecundity ranged from 166 to 366 eggs. The results showed that fecundity had a close relationship with fish body weight where the correlation coefficient (r) was 0.9653 and the coefficient of determination (R²) was 0.9319. While the long relationship with fecundity has a moderate relationship where the correlation coefficient (r) obtained is 0.4079 and the coefficient of determination (R²) is 0.1664. This indicates that fish weight is better used to estimate the value of fish fecundity than body length. Keyword: Betta fish, Fecundity, Body weight, Body length
