Problems in the fish hatchery sector often occur such as high egg mortality or low quality of fish eggs. Optimizing biosecurity is one of the efforts to improve the quality of fish eggs, for example by adding disinfectants such as iodine, ozone, and peracetic acid. The use of chemical disinfectants will produce good results if the right dose, time, and commodity are used. In this study. This research aims (1) to determine whether the use of chemicals including iodine, ozone, and peracetic acid had an effect as a disinfectant to increase the hatching rate of grouper fish, (2) to determine the level of effectiveness and efficiency of the use of chemicals as a disinfectant. This research is an experimental research type. The research subjects included in the study were cantang grouper fish eggs at PT. Pakarti Daksa Segara who used the exploratory sampling method. The conclusion of this study indicates that there is an influence on the growth rate of the use of iodine, ozone and, peracetic acid chemicals as disinfectants of cantang grouper eggs and there is a comparison of the effectiveness and efficiency of the use of the three chemicals which includes the percentage of the hatching rate, the cost of the disinfectant material and the time, which is needed in the use of the disinfectant. Iodine has the best level of effectiveness from the comparison of hatching eggs of cantang grouper and peracetic acid is the most efficient type of chemical.

The aims of this study were to determine clinical symptoms, mortality, prevalence, and histopathology of Cantang hybrid grouper fish infected with Oodinium sp. on the Cantang. The study was conducted by direct observation of clinical symptoms, calculating the number of fish mortality, and measuring the quality of water in the tank using the Cantang. While histopathology was conducted in the laboratory using 10 samples of sick fish with an average total length of 10.6 ± 0.69 cm and a weight of 18.6 ± 1.77 g. The results showed that the fish seen swimming weakly on the surface of the water near aeration or standing still at the bottom of the tub, decreased appetite, had pale or darker body color, and were thin. Observation of skin and gill mucus under a microscope showed the presence of ectoparasites Oodinium sp. in massive quantities in almost every gill sheet. The mortality of fish infected with Oodinium sp. in the Cantang of 26.84±3.9%, with a prevalence of 49.59%. Histopathologically the gill lamellae of fish infected with Oodinium sp. shows the occurrence of hyperplasia which causes the union of several gill lamellae.

Hybrid grouper is a variety of grouper that has become increasingly popular in recent years. The development of grouper cultured in Indonesia utilizing the Recirculating Aquaculture System (RAS) is currently underway; nevertheless, fish cultured in the RAS system continue to struggle with infectious diseases, one of which is VNN (viral nervous necrosis) infection caused by piscine betanodavirus. The purpose of this study was to know the clinical sign, mortality, and histopathology of cantang grouper (Epinephelus fuscoguttatus x E. lanceolatus) infected with VNN in RAS. Fish samples were obtained from the hatchery using RAS. This research uses a mixed methods approach and the type of research used is exploratory research. The parameters observed were clinical signs, mortality, and histopathology. Water quality, including temperature, DO, salinity, and pH at the time of VNN infection, was used as secondary data. The results showed that clinical signs of sick fish were weakness, staying at the bottom of the rearing tank, decreased appetite, swimming with the stomach facing up and the body dark in color. Fish mortality occurred for ± 10 days with a peak of mortality reaching 26.86 ± 7.45% on day 9 from initial signs. Histopathology result, diseased fish showed vacuolization in the brain and retina of the eye.

Caulerpa lentillifera is a promising source of nutrition for the future because of its benefits and composition for human consumption. Cultivation is believed to increase the availability of products both in quantity and quantity, without relying on exploitation in nature. The interesting thing about this research is that the cultivation of Caulerpa lentifera is carried out together with the cultivation of Haliotis squamata. This study aims to determine the effectiveness of the use of abalone cultivation wastewater on the growth of Caulerpa lentillifera and the use of fertilizers in water media in increasing production yields. The study used an experimental method with a completely randomized design with treatment. Growth parameters consisted of absolute weight, number of ramili, and chlorophyll index. The integrated cultivation of Caulerpa lentillifera with Haliotis squamata shows the effectiveness of water use both in terms of quantity and quality in integrated cultivation. Growth analysis with parameters of growth rate, number of ramili, and chlorophyll index showed an increase in Caulerpa lentillifera production could be carried out with the addition of fertilizer, this was proven to stimulate growth, increase the number of ramie, and increase the chlorophyll content of Caulerpa lentillifera. Fertilization with N : P proportion of 16 : 4 ppm every day was proven to increase absolute weight, proportion of assimilator, proportion of assimilator worth selling.

Seaweed commodities are one of the products in the fisheries and marine sector that has the potential to be developed. One type is sea grape or commonly known as Caulerna lentillifera which is very widely spread in waters throughout Indonesia. This research method is descriptive quantitative, this research was conducted to determine the heavy metal content in natural sea grapes and cultivated sea grapes. The research procedure consisted of pre-research process to observation and checking of heavy metal content. The results of research on heavy metal content of cultivated sea grapes get good results, while for nature there are levels of heavy metals Pb so it can be said that it is not very good. The results of measuring the length of ramuli in the first week was 3.3 cm, the second week was 4.4 cm then increased in length in the third week to 5.8 cm, and ended in the fourth week with an increase in length of 6.9 cm. The results of the calculation of the number of ramuli in week 1 showed that the average number of ramuli was 12, the average number of ramuli in the first week increased to 14 in the second week and increased in the third week to 17 then ended in the fourth week with an average of 19 ramuli. The quality of water used in the cultivation of sea grapes in Musi Village and natural sea grapes is still in normal status.

Air merupakan media budidaya yang sangat penting dalam perikanan, seiring berjalannya waktu, ketersediaan air bersih semakin sulit untuk didapat, sehingga menjadi kendala dalam berbudidaya, dengan menggunakan sistem resirkulasi akan memutar air secara terus menerus sehingga mampu menghemat air dan kualitas air tetap terjaga. Adapun kualitas air yang dapat mempengaruhi ikan lele yakni, Amonia, Nitrit dan Nitrat. Sistem resirkulasi menggunakan filter dengan perbandingan menggunakan filter konvensional dan filter konvensional yang diambah dengan filter biologi menggunakan tanaman kangkung. Tujuan dari penelitian ini untuk melihat apakah terdapat perbedaan konsentrasi amonia, nitrit, dan nitrat dari sistem resirkulasi yang tidak menggunakan tanaman dengan sistem resirkulasi yang menggunakan tanaman kangkung serta melihat sistem mana yang lebih efektif dalam memperbaiki kualitas air. Pengambilan sampel air dilakukan 7hari sekali selama 1bulan. Parameter yang diamati adalah Amonia, nitrit, nitrat. Data disajikan dalam bentuk grafik serta dianalisis secara deskriptif kuantitatif. Amonia dan nitrit perakuan A, nilai rata-rata yang diperoleh cenderung lebih tinggi dibanding dengan perlakuan B namun rata-rata masih berada di bawah ambang batas yang telah ditentukan, sedangkan konsentrasi nitrat menunjukkan nilai yang tinggi pada perlakuan B dibandingkan perlakuan A. Terdepat perbedaan kualitas air dari kedua perlakuan, kualitas air perlakuan B lebih baik dilihat dari variabel amonia nitrit dan nitrat dengan menghasilkan SR tertinggi sebanyak 86,6%.
