Abstract

This study aimed to determine the best combination of feed on the growth and survival of larval fish catfish (Clarias gariepinus). This study  used completely randomized with six treatments including treatment A: Artemia, B: Tubifex C: Pellet, D:  combination of (50%) Artemia + (50%) Tubifex, E:  combination of (50%) Artemia + (50%) Pellet, and      F:  combination of (50%) Tubifex + (50%) Pellet. Each treatment consisted of three replications. The result showed that the combination of  50% artemia + 50% tubifex could promote the growth length of larvae of 4,003 cm, weight of larval of 0.633 g,  and larval survival was 79%.  This combination was the best combination for the growth and survival of catfish larvae.   Keywords: Combination of feed, Clarias gariepinus, larvae, growth, survival

Abstract

This research was conducted by purposive random sampling method with 3 points. Data were analyzed descriptively by comparing the environmental quality standard based on the Ministry of Environment No. 51. 2004. Results of laboratory analysis was the content of Cadmium (Cd) was still below the allowable threshold. Compared to Cd content of fresh water which was 0.0002 mg/L, the Cd content found in this research was lower that was 0.0001 mg/ L.   Keywords: Kadmium (Cd), Logam berat, Baku Mutu, Pantai Malalayang, RS Prof Kandou.

Abstract

The aim of this study was determine the effect of temperature shock on hatching capability of the catfish eggs and its larval survivals.The study was conducted at the Board of Freshwater Aquaculture (BBAT ) in Tatelu  Dimembe District, North Minahasa Regency, North Sulawesi Province. Twelve tanks were set in this experiment. Two hundred (200) eggs were put in each tank with controlled temperature of 25 C, 27 C , 29 C , and 32 ºC. Each temperature was replicated 3 times. The experimental design used in data analysis was completely randomized design (CRD).  The results showed that the treatment temperature showed significant effect on  hatching of  eggs, while the difference in temperature had no effect on the survival rate of catfish larvae.   Keywords:  Temperature shock, eggs, hatching capability, survival rate,  larvae, Clarias gariepinus.

Abstract

Kijing Taiwan (Anodonta woodiana) is a freshwater mussels that have the potential to be cultivated commercially. This study was conducted to determine the growth of Kijing Taiwan with a difference substrate. The method used in this study is the experimental method using a completely randomized design  4 treatments and 3 replications. The results showed that the absolute growth and relative good growth found in sandy mud substrate. But statistically difference substrate no  effect on the growth of Kijing Taiwan (Anodonta woodiana).   Keywords : Anodonta  woodiana, absolute growth, relative growth, substrate .

Abstract

This study aimed to determine the effect of several different types of feed on absolute length growth, relative length growth, and survival rates are gouramy larvae (Osphronemus gouramy). This study used four treatments, with three replications. The treatments tested were four different types of feed on the larvae of gouramy, among others; feed worms Tubifex sp., Artemia sp.,boiled chicken egg yolk and finely pelleted feed FF-999. The experimental design used was completely randomized design.      The results showed that different types of feed provided a significant influence on the absolute length growth, relative length growth and survival of larval gouramy (Osphronemus gouramy). Feed worms Tubifex sp. give the best results with an absolute value growth of 1.34 cm length, relative length of 148.87% growth, and survival of 34%. Feed worms Tubifex sp. is the best feed in promoting growth and improving survival of larval gouramy (Osphronemus gouramy).   Keywords : Larvae,  gourami, Tubifex, Artemia, feed

Abstract

The research intended to determine the optimal concentration of honey supplemented in sperm dilution to improve sperm motility, fertilization and eggs hatchability of catfish (Clarias sp). Experimental design used was a Complete Randomized Design (CRD) with four treatments each with three replications. The concentration of honey used astreatments were A (0 mL + 100 mL of physiological NaCl), B (0.60 mL + 99.40 mL of physiological NaCl), C (0.65 mL + 99.35 mL of physiological NaCl), D (0.70 mL + 99.30 mL of physiological NaCl). Parent used consisted of one female with 1.5 kg weight and the male parent with 1 kg weight.  Sperm dilution containers used was 12 plastic cups and the container fertilization and hatching eggs container used was 12 brass plates.  Spermatozoa motility observation performed immediately after dilution process. Fertilization observation was performed after 12 hours of fertilization process, and egg hatchability observation was performed after 60 hours of fertilization.  The research results showed that the addition of honey in sperm dilution contributed significant effect on spermatozoa motility, fertilization and eggs hatchability. The addition of 0.70 mL honey in sperm dilution was the best indicated by the average percentage of spermatozoa motility 83.33%, fertilization 82.50% and eggs hatchability 79.67%.   Keywords: Honey, sperm dilution, spermatozoa motility, fertilization, eggs hatchability.

Abstract

White shrimp culture have been developed in some part of brackish water pond area in Indonesia, either in extensive, semi intensive or intensive technology and it resulted increasing on Indonesian shrimp culture production.  At post larval stages, the pleopods become fully developed and functional. The animals grow very fast in terms of size and are able to swim freely although early post larvae are still planktonic. This research was done to know post larval rearing in Hatchery of PT. Banggai Sentral Shrimp. Preparation of basic facilities such as larval rearing tanks, water supply and aeration system is one of the most important activities in hatchery operation.  Good water quality should be strictly maintained especially during this phase of larva rearing.
