Abstract

Vanname shrimp (Litopenaeus vanname) is still a favourite in shrimp culture production in Indonesia, since it has faster growth advantages. However, the White spot syndrome virus (WSSV) attack is still a big threat for farmers, because it can proliferates rapidly and cause mass mortality of 90-100%. The UPT Pengembangan Budidaya Air Payau in Bangil maintains vanname and controls virus infection by detecting through a molecular approach. Detection using the Nested PCR method with IQ 2000 kit with molecular weight marker 848 bp, 550 bp, 296 bp. The sample will be tested positive if the bands that appear are in the size 296 bp and / or 550 bp . The results of the detection in shrimp rearing ponds were negative (-) because only the band 848 bp that showed, it was mean the shrimp free from WSSV infection. Water quality data shows that the shrimp rearing environment is in optimal conditions.

Abstract

Applications for handling hybrid grouper eggs (Epinephelus lanceolatus x Epinephelus fuscoguttatus) include the initial egg handling process, egg selection, egg counting and egg observation. The initial handling of hybrid grouper eggs (Epinephelus lanceolatus x Epinephelus fuscoguttatus) begins with stripping the female tiger grouper and male giant grouper to get eggs and sperm. Mixing eggs and sperm is done using chicken feathers. Egg selection is done to separate good and bad quality eggs. Good quality eggs will float on the surface, are round, transparent in color and have a core. Poor quality eggs will sink to the bottom and become milky white. The egg calculation technique uses the manual method with the help of a petri dish and a 20 ml beaker glass. Observation of eggs using a microscope magnification 40x. The fertilized egg has a transverse line between the nucleus of the egg which is a developing embryo. The unfertilized egg does not have a transverse line which indicates the egg does not have an embryo.

Abstract

Fish health is an important problem faced by Cantang grouper (Ephinephelus sp.) Hatcheries. Broodstock health management needs to be managed properly so as not to decrease the quality and production of Cantang grouper seeds. Cantang grouper broodstock health management includes the process of maintaining grouper broodstock, feeding, disease control and water quality management. The data collection method is done by recording the results of active participation, interviews and observations. Broodstock grouper cantang are maintained in ponds made of concrete with sizes ranging from 150 meter kibik and a depth of 3 meter. Pond cleaning is carried out once or twice a month with the addition of 2 kg of chlorine / 150 tons of water. Grouper broodstock is fed 10 kg for 24 broodstock. feed in the form of trash fish, squid, mackarel, vitamin C and vitamin E. The types of diseases that often attack grouper broodstock are Criptocaryon irritans, Benedia sp and Vibrio alginolyticus. Water quality parameters measured in grouper broodstock ponds are salinity and temperature. The water salinity in broodstock ponds ranges from 34 - 35 ppt and temperatures range from 27-31 derajat celcius.

Abstract

Larvae health management is a key factor in the hatchery of humpback grouper (Cromileptes altivelis) to prevent mass larval deaths and cause financial losses. Management of humpback grouper larvae health includes larval rearing, larval feed management and larval disease control. The primary data collection method was carried out in 3 ways, namely observation, active participation and interviews. Secondary data retrieval by studying literature from various related sources. The humpback grouper larvae were reared in the hatchery to control the temperature and condition of the larvae. Larval ponds are sterilized with 3-5 ppm chlorine in the morning and rinsed thoroughly so that no chlorine remains. Larvae were reared from the age of 1 day to 45 days. Feeding the larvae was started when the larvae were 2 days old with Nannochloropsis occulata. Rotifers were given when the larvae were 2-3 days old with a density of 5 individuals/ml. Artemia was given when the larvae were 20 days old until the age of 40 days. Pellets are given when the larvae are 8-10 days old with a pellet size of level 1. The pellet size continues to increase according to the larva's mouth opening. The disease that often attacks larvae is Viral Nervous Necrosis (VNN). The characteristics of larvae infected with VNN are reduced appetite, weak movement, larvae float on the surface and lie on the bottom of the pond. VNN attacks can only be overcome by prevention. The bacteria that often attack the larvae are Vibrio alginolyticus. Vibrio alginolyticus can be treated with antibiotics or non-antibiotics. The use of antibiotics is not recommended because they have negative side effects, so you can use other alternative medicines derived from herbal plants (phytopharmaceuticals).

Abstract

The foreign predatory fish Mayan cichlid (Cichlasoma urophthalmus) in the waters causes a reduction in biodiversity and is very dangerous for the sustainability of the aquatic ecosystem in Indonesia. This study aims to analyze and describe the catch of the mayan cichlid and examine the negative impact of finding this species in the Tanjungan Water Pump Jakarta. This study used the desk study method, observations by informants in the field and species identification methods based on morphological observations of Miller et al. (2005) and Nico et al. (2007). The finding of the Mayan cichlid fish species in the Tanjungan Water Pump Jakarta is an alarm or sign of the negative impacts of invasive fish to the government so that they can develop regulations that are focused and directed towards the spread of invasive species in Indonesian.

Abstract

The development of seawater cultivation (marineculture) leads to important economic commodities, one of which is shellfish such as abalone shells (Haliotis squamata). Abalone is very popular among people both domestically and abroad, this has caused the demand for abalone to increase. However, most of the abalones are obtained from wild catches. This is what causes the abalone population in nature to decline. Therefore, abalone cultivation, especially seeding, is one way to meet market demand. Problems arise when the larvaes are in the larvae phase, which is susceptible to pest attacks and disease and feed that is appropriate to the size of the abalone larvaes. This research is descriptive research where the primary data collection method is carried out in 3 ways, namely observation, active participation and interviews. This activity aims to find out pests and diseases that attack abalone larvaes and the type of feed that suits the size of the abalone larvaes.

Abstract

Foreign fish, especially predatory fish in Indonesian public waters, are very dangerous for the local ecosystem, foreign predatory fish can become the main predators and can cause an imbalance in the ecosystem. From this study we report the catch of foreign predatory fish from the jaguar cichlid species (Parachromis managuensis) from Central American waters caught in Nyunyur Reservoir, Blitar Regency, East Java. The method in this study used a desk study and jaguar cichlid species identification method using morphological observations based on Kullander and Hartel (1997). This catch is a warning and an important note for the relevant agencies regarding the invasion of the jaguar cichlid species in the Nyunyur Reservoir as an initial step in monitoring aquatic ecosystems.

Abstract

Foreign predatory fish species in Indonesia have the potential to threaten the local ecosystem by becoming the main predators that disrupt the balance of the food chain in local waters. Through this research, we want to report the invasion of the species Parachromis managuensis, which originates from Central American waters. This fish species has been found in significant numbers and sizes in the waters of the Penjalin reservoir. In this study, a morphological approach was used to identify the Parachromis managuensis species. The capture of this species was recorded as the first step in efforts to monitor the reservoir water ecosystem in Brebes so that it remains balanced. Results and discussion, including a description of the morphology of the Parachromis managuensis species that have been caught, can be found in this research report.
