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

Plankton are microscopic organisms that exist in the waters of shrimp ponds. The purpose of this study was to determine the profile of plankton dominance in white shrimp (L. vannamei) aquaculture ponds. This research was conducted using an ex-pose facto causal design method in intensive white shrimp culture ponds. The results of this study showed that in the research shrimp ponds, 4 main genera of plankton were found, namely the genus chlorophyceae consisting of species chlamydomonas sp., chlorella sp., oocystis sp., tetracelmis sp., genus cyanophyceae consisting of species anabaena sp., chroococcus sp., microcystis sp., oschillatoria sp., genus Euglenophyceae namely phacus sp. and the genus Dinophyceae which consists of the species gymnodinium sp. noctiluca sp. peridinium sp. prorocentrum sp. Overall the level of dominance of abundance and community dominance index was dominated by plankton of the genus chlorophyceae as much as 1.03E+06 cells/ml and a dominance index of 82.40%. Then from the genus chlorophyceae the dominant species is plankton species chlorella sp., with an abundance of 7.50E+05 cells/ml and a dominance index of 73%. The conclusion of this study is that plankton in the research ponds are dominated by the genus chlorophyceae which consists of dominant species of chlorella sp and chlamydomonas sp, oocystis sp, tetracelmis sp which are predominant.

Abstract

Lemuru (Sardinella lemuru)is the most catches in Banyuwangi. This fish called pelagic fish that swim on the surface of the sea. The abundance of lemuru catch makes this fish have a role and benefit for the society. However, fish is also quickly to spoil after harvesting. Without the preservation process, the fish is only suitable for consumption within a day after being caught. Various preservation methods have been carried out, one of which is salting and drying aimed to reduce the moisture content in the fish body, so that didn’t give chance for microorganism to breed and didn’t affect the fish quality. This study was used descriptive method with data collection techniques through primary data and secondary data. Data collection carried out with observation, interview, active participation and literature study. Research result in Istana Muncar Ikan Banyuwangi SMEs included raw material used in food processing in SMEs was lemuru (Sardinella lemuru) obtained from Muncar Port. The fish was treated with brining method by soaking fish of dilute salt solution of 30-35% from total weight of fish. After brining, drying process was carried out under the sun for 1 day and dried salted fish produced, has distinctive smell, salty taste, normal colour, also good shape. Salt content of 13-17% by weight of salted dried fish.

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

The use of fish as raw material for surimi continued to grow along with the increasing demand for surimi-based processed products. The fish used from marine fish to freshwater fish. The use of fresh fish as raw material greatly affected the quality of surimi. The morphological characteristics of fish raw materials affected the yield of fish meat, this can be seen in the yield of each fish. This research used two types of fish, namely Malong / Daggertooth pike conger fish (Muraenesox cinereus) and Kembung / Mackerel fish (Rastrelliger brachysoma). In general, the results of the proximate test showed that the protein levels in the fish used were not significant. Malong fish was very potential to be used as raw material for surimi because it produced the highest yield, which was 66.67% with 62.44% myofibril and 25.6% sarcoplasm. Kembung/Mackerel fish in this study resulted in the lowest yield of 37.00% with 59.69% of myofibril and 46.6% of sarcoplasm. Gel formation in surimi was strongly influenced by myofibril and sarcoplasmic proteins. Gel formation in fish meat was strongly influenced by the presence of salt-soluble proteins in the form of myofibrils (actin and myosin). On the other hand, if fish meat contained more water-soluble protein (sarcoplasm), it would be relatively reduce its gel formation ability.

Abstract

Kappapyhcus alvarezii seaweed or more commonly known as Eucheuma cottonii is a potential commodity to be developed because seaweed has many benefits. The problem found in the development of seaweed in Indonesia is the number of pests and diseases in seaweed, especially ice-ice. In vitro culture techniques have become an alternative to help overcome the problems that are often faced in the provision of seeds through conventional means. There are 6 stages in seaweed tissue culture, namely broodstock acclimatization, callus induction, callus/micropropagule regeneration, micropropagule regeneration, plantlet acclimatization and seed propagation in the sea. During the observation, water quality was still in the normal range, namely temperatures ranging from 25-30 0C, pH between 8.16-8.35 and salinity 34-36 ppt.

Abstract

Testing of ectoparasites on water quality in infections that occured in tilapia in aquaculture activities in Rawa Pening. The purpose of this study was to determine the exposure to the abundance of ectoparasite bacteria that infected the growth of tilapia in Rawa Pening. This study used experimental method and purposive sampling with data processing in a descriptive survey. The data analysis used was analysis of variance (ANOVA) with the aim of knowing the effect of sampling and the parameters tested, this test was carried out 4 (four) times for water quality and ectoparasite observations 3 (three) times for testing to obtain the accuracy of data sampling. The results of this study showed that there was an infection with levels of ectoparasites identified from the types of Streptococcus sp, Lernaea sp, Aeromonas sp, and Trichodina sp. These bacteria attack fish with the highest number or total exposure in the Tuntang area. The reason was, currently water hyacinth was being cut down as one of the local government programs to reduce the blooming of water hyacinth (Eichhornia crassipes) of 7.92 mg/L, pH levels 7.59, ammonia levels 10-20 mg/L and nitrate levels 0.5 mg/L were still in optimal conditions from the results carried out.

Abstract

The low production and quality of pearls produced from the cultivation process, one of which iscaused by the less than optimal quality of pearl oysters. Spawning is a determining factor in hatcheryactivities. Therefore, in an effort to increase production, it requires strategies and improvements inthe pearl oyster spawning process. This study aims to apply the temperature shock method as an effortto increase productivity and success rate of pearl oyster hatchery. The results of observations ongonad maturity in pearl oyster broodstock obtained data from a total of 200 broods consisting of 135male broods and 75 female brooders aged 3.5 years, the percentage of perfectly gonadally maturebroodstock was 11.85% and 12%, respectively a total of 25 individuals. The results of spawning pearloyster broodstock through the temperature shock method of a total of 18 broods observed were 12brooders or 66.7% which spawned perfectly. The results of the observation of the spawning process ofpearl oyster broodstock showed that from 8 female broodstock ± 90,000,000 eggs were obtained witha hatching rate of 70% with a spat harvest of ± 1,575,000 individuals or 2.5% of the total hatchedlarvae final yield.
