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.

Vannamei shrimp (Litopenaeus vannamei) is one of the commodities that is a priority in aquaculture development activities in Indonesia. The success of vannamei shrimp culture is influenced by various factors such as fry quality, feed quality, land carrying capacity, application of biosecurity and good water quality management. Water quality is closely related to the phytoplankton community contained in a waters. This study aims to analyze the abundance and dominance of plankton species found in pond waters. Monitoring the abundance of phytoplankton was carried out in 4 plots of vannamei shrimp aquaculture ponds at the Brackish Water Aquaculture Fisheries Center (BBPBAP) Jepara, namely plots A51, A51, A61 and A62. Identification and calculation of phytoplankton cells were carried out using a haemocytometer and Sedgwick. The results of the analysis showed that the highest abundance of phytoplankton was found in plots A61 at week 9 with a cell number of 36.73 x 106 cells/L, while plots A51, A52 and A62 decreased. Overall plot A62 had better water quality conditions when compared to plots A51, A52 and A61 indicated by the phytoplankton abundance value of 34.63 x 106 cells/L at week 9 and the dominance index of green algae, namely D > 0.5.

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

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.

Indonesia has a lot of potential in natural resources, one of which is seaweed. Seaweed is one of the natural ingredients that contain water-soluble dietary fiber. The fiber content in seaweed can be categorized as a functional food. The fiber content in seaweed varies, from 36-60% dry weight, 55-70% of the former percentage is soluble fiber consisting of alginate and carrageenan with varying amounts depending on the type of seaweed and environmental conditions. The dietary fibers are useful for disease prevention and health maintenance. Dietary fiber can prevent several diseases, including coronary heart disease (cardiovascular). The effect of dietary fiber according to Liu et al (2002) is a very high fiber diet (55 g/1,000 kcal) which resulted in a 33% reduction in LDL cholesterol (Low-Density Lipoprotein) in two weeks period. The mechanism of dietary fiber reduces cardiovascular disease since it is able to bind bile acids (the end product of cholesterol), thereby preventing its reabsorption from the intestine. Cholesterol that is bound to bile acids and lignin/pectin cannot be absorbed by the intestines but will be excreted in the feces.

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.

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.
