Abstract

An underwater visual census (UVC) conducted to assess the biophysical conditions of the two marine protected areas (Antulang Marine Protected Area and Andulay Marine Protected Area) in Siaton, Negros Oriental revealed slow recovery from severe damage resulting from Typhoon Sendong in December 2011, suggestive of “coral-algal phase-shift”. Live hard coral (LHC) cover was consistently poor in the survey sites (2.25±0.78 % in Antulang Marine Protected Area; 1.25±0.50 % in the Control Site; and 3.33±0.17 % in Andulay Marine Protected Area) following destruction by the typhoon and colonization of algae (between 37-53%), dominated by Bornetella oligospora. Mean total fish biomass (including fusiliers and schooling juvenile Caranx sexfasciatus) was highest in Antulang Marine Protected Area at 70.60±28.07 kg/500m2 (equivalent to 141.21±56.14 tonne/km2) while lowest in Andulay Marine Protected Area at 9.83±4.32 kg/500m2. Mean total fish density was highest in Antulang Marine Protected Area at 597.0±114.7 fish/500m2 followed by the Control Site with 361.7±159.0 fish/500 m2, while Andulay Marine Protected Area had 200.7±31.6 fish/500m2. Fish species composition was slightly altered, i.e. decline in coral-dependent species such as damselfishes. Keywords: coral reef, macroalgae, phase-shift, resilience, recovery, typhoon

Abstract

The important thing in cultivation of freshwater crayfish is the availability and quality of seed. The use of appropriate method could support the production of good seed, therefore in this research we conduct the seed production methods, one is hatching in a natural way, while the other is separating the eggs from the female. On this research, we used 5 females and 3 males of freshwater crayfish (LAT) and placed them in a round glass fiber container with a diameter of 1.5 together with aeration and small pipe (as shelter).  Initial average weight of the female and male, respectively from 74.5 to 76.7 grams and an average length of 6 cm. These female and male freshwater crayfish were acclimatized before spawning. Gonadal maturation performed together in a single glass fiber container for 2 months.  In this study routinely measured water quality parameters including temperature, acidity (pH) using cremometer, also dissolved oxygen and CO2. Egg test used for this study was given as treatment A which is 150 eggs incubated by each female and treatment B which is 150 eggs separate from each parent and left to hatch by itself.  Females that incubate their eggs and the separating eggs were placed in different aquarium (60 x 40 x 40 cm) equipped with modified pipes for shelter. The results of water quality parameter are temperature 24.5-26.5 oC, pH 7, DO 6.43 ppm and CO2 0.04 ppm. Egg incubation period lasts for 45 days.  From this research the following conclusions can be drawn between the two treatments were performed in the study, natural incubation method gives much better results for egg hatching of freshwater crayfish.   Keywords: egg incubation method, freshwater crayfish, Cherax quadricarinatus, reproduction

Abstract

This research aimed to diagnose bacterial diseases on nile tilapia cultured in stick net cage in Lake Tondano. Fish samples were taken from three locations of net cages in Lake Tondano namely Paleloan, Eris and Remboken villages. Three samples of fish were taken from each location/village. The samples taken showed clinical symptoms of bacterial infection such as hemorrhagic on the abdomen, the base of the fin, anal and chest, irregular swimming fish, hemorrhagic on the gills, fish refuse food, remain silent on the outskirts of net cage. Bacteria were isolated by using a sterile loop from head kidney (anterior kidney), which is located on the front, below the spine near the head. Bacterial cultures were performed on TSA media by making a zigzag scratches. The petri dish containing bacterial isolates were subsequently incubated in an incubator at a temperature of 35oC for 24 hours. The water quality parameter data measured consisted of temperature, Dissolved Oxygen, pH, ammonia, brightness. The results of the study showed that farmed tilapia in Lake Tondano has been infected with Aeromonas hydrophila that causes MAS (Motile Aeromonad Septicemia). The water quality, both chemical and physics around the net cages in the Lake Tondano was still in good condition and suitable for fish cultivation.   Keywords: Oreocrhomis niloticus, Bacterial disease, septicemia aeromonad motile, fixed net cage, Lake Tondano

Abstract

The aim of this study was to know the  applied technology and the production value of the aquaculture activities in the waters of  Lake Tondano and to identify factors influencing aquaculture production in Tondano lake. Data collected  consisted of primary and  sekunder data.  Primary data  were collected by conducting a survey to fish-farmers as respondents around the lake Tondano.  Operational aquaculture data were obtained  by interviewing the fish farmers and by observation.  Secondary data were collected from various  institution  such as Minahasa  Fisheries  Office  ,  Office of  Village Head and Fish-farmer  Group  Administrative Centre.  Collected data were  descriptively analyzed  and presented in the form of tabulation and various model of diagram.  Fluctuated data in aquacultural production value  and the number of  operated  KJT  during the periood of  2001 to  2014 was analysed by using linear regression  and correlation. The aquacultral production value  of the lake Tondano in  2014 was  estimated only 1227,3 tons /year.  The number of operated  KJT  only remained 1203 units.  The production value decreased consistently  from 2003 to 2014.   Statistical analysis showed that during  2001-2014 there was a reduction about 1.236 ton every year in aquacultural production, and  607 units of operated KJT.  There was a  very strong correlation  between  time  (year) and the  the aquacultural production, and also between  time (year) and  the number  of  operated KJT.  There were 3 important  factors  influencing the aquacultural production value of lake Tondano, which were: environmental, technical and economic factor.   However, the primary factor  was  ‘economic’ factor.  The  ‘very high price’ of the fish formulated diet  and  the "very low price”  of  the produced fish were the main causes of the problem.   The fish farmers could not afford the invesment and operational cost.   Environmental degradation of  Lake Tondano waters  also significantly  influenced the operation of aquacultural activities.   Keywords:  Production, technology, aquaculture, Lake Tondano
