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

Koi fish (Cyprinus rubrofuscus) is included in freshwater ornamental fish commodity which has high economic value. As high of the market demand, it must be balanced with the increase of Koi fish production, especially in the hatchery sector. One effort that can be done is by preserving sperm with the addition of a solution of palm juice and ringer lactate. The purpose of this study was to determine the effect of the difference and the best value of the concentration of palm juice in ringer lactate during the storage period on the fertility power of Koi Fish sperm. The research method that used is the experimental method with the main parameters of motility, viability, fertilization, hatchability, survival rate and supporting parameters of macroscopic quality of fresh sperm and water quality. The results showed that the addition of palm juice and ringer lactate gave a very real effect on the level of motility with the best value on treatment B that is equal to 50.33%, the level of viability with the best value at treatment B that is equal to 64.67%, fertilization rate with the best value at treatment B that is equal to 84,91%, hatchability level with the best value at treatment B that is equal to 69,80%, but no significant effect to survival rate of the juvenile. The function of palm juice and ringer lactate is providing energy and keep the balance of the fluid in sperm that is useful to keep sperm still alive and still moving.

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

Tilapia has several varieties produced from cross-breeding. The results of cross-breeding produce new varieties in tilapia with their respective advantages in terms of survival and growth. But until now there has been no research on survival studies and the growth rate of some of the best Tilapia fish varieties. This study used a completely randomized design, 4 treatments 3 replications. The treatments given were (A) Gift Tilapia, (B) Red Tilapia Fish, (C) Jatimbulan Tilapia Fish and (D) Solid Tilapia Fish. Tilapia seeds maintained in treatment B (red tilapia) gave the highest survival value of 88.87% and the lowest value in treatment A (gift tilapia) and D (stocky tilapia) were 83.33%. In treatment A (Gift Tilapia) gave the highest length growth value of 1.6-1.7 cm and the highest daily weight growth rate of 0.085 gr / day, while in treatment B (Red Tilapia) gave the lowest length growth value of 1.3-1.45 cm and the lowest daily individual weight growth rate of 0.062 gr / day. Water quality parameters such as pH, DO and temperature measured during the maintenance period are in the normal range, so they do not have a significant effect on the growth of tilapia fish. The highest FCR was obtained in treatment B (Red Tilapia) with an average of 0.90 and the lowest FCR was obtained in treatment A (Tilapia Gift) with an average of 0.69.

Abstract

The low survival value of seedlings is due to stress. Naturally cells in fish respond to the presence of environmental stressors by producing stress proteins such as mitogen-activated protein kinases (MAPKs). MAPKs are one of the important cellular signaling systems in fish as a response to the presence of environmental stressors. This study uses a completely randomized design method, 3 treatments 3 replications. The treatments given were (A) 28 o C temperature treatment, (B) 30 o C temperature treatment, (C) 32 o C temperature treatment, observations made were measurements of p38 mapk levels, survival and physical and chemical parameters. From observations of tissue staining (p38 MAPK) in the above table shows that the best results obtained in treatment B (30 o C) because there are many negative MAPK, so that at experience 30 o C the fish did not significant stress, and the highest survival rate was 83.3 %.

Abstract

The business of arwana hatchery is now grew up. One of the main factors which can increase the successfulness of arwana hatchery is water quality parameter, such temperature. This research was held on February to April 2014 in BBI Punten, Batu. The silver arwana hatchery was from “MINA KARYA KOI CENTER” Sleman witch its height 5,3 cm and weight 0,5 gr. It was treated in the aquarium 100x40x50 cm3 with its density 10 fry/aquarium. The treatment which given such (A) the temperature is 26oC, (B) the temperature is 28oC, and (C) the temperature is 30oC in 5 time repeated. The silver arwana hatchery which treated in thetemperature 26oC has the survival rate as 78% and the lowest score for temperature 30oC treatment is 20%. In 26oC temperature, the average of height growth is -2,7 cm and the average of weight growth in a day is 2,05%.
