Abstract

Physiological condition of fish is affected by environmental condition and nutrient input. The growth of Pangasius hypopthalmus is improved by reared it in short photoperiod. To understand the blood condition of P. hypopthalmus reared in manipulated and fed with turmeric enriched pellets has been conducted in July-October 2019. The fish was reared in tarp ponds, 30 fishes/pond (6-8 cm TL). Manipulated photoperiod treatments were 24 hours dark, 18 hours dark and natural photoperiod, while turmeric treatments were 0.5, 0.7, and 0.9 g/Kg feed. Parameters measured were erythrocyte total, leucocyte total, hematocrit and leucocryt of P. hypopthalmus. Result shown that in general the blood condition of the fish there were no abnormality. Blood condition of all fish treated were erythrocyte total were 2.41-2.87 x106 cells/mm3, leucocyte was 2.96-8.82 x104 cells/mm3, hematocrit were 22.9-36.2 % and leucocryt were 0.8-1.8 %. Based on data obtained it can be concluded that manipulated photoperiod and turmeric enriched pellet do not negatively impact the health status of fish in general.

Abstract

The presence of fish cage culture activities may affects the environmentalcondition as the remain of fish feed pellets may enter the surrounding water and itmay serve as food resources for wild fish species such as Puntius schawanefeldi .To understand the impact of fish floating cage activities on feeding habit of P.schawanefeldi and economical condition of traditional fishermen in the KotoPanjang Dam, a study has been conducted on April to June 2013. Fish sampleswere collected from 5 stations, Stations 1, 2 and 3 were in the dam, around thecage, while station 4 and 5 were in the area that has no cage. Data of 24 hoursfish feeding habit were obtained by capturing fish for a 3 days period (once/ 3hours, at different time). Stomach content was then removed, identified andanalyzed using a volumetric method. Results shown that the stomach content offish living around the cage and the fish living far from the cage are different.Stomach content of the fish from the 1 st , 2 nd and 3 rd stations was dominated byfish feed pellet remains (>90%), while that of the fish living in the area with nocage was dominated by debris (>90%). These facts indicate P. schawanefeldi is anopportunist fish, its feeding habit is changing. Fish living around the cage preferto feed on commercial fish feed pellet remains. The presence of P. schawanefeldiaround the cage, however, increase the income of traditional fishermen as theyable to caught around 50 – 80 kg of fish/ week, compare to 10 – 20 kg fish/ weekin the 4 th and 5 th stations. Data obtained indicate that the presence of fish cageaffect the feeding habit of P. schawanefeldi and positively affect the income of thetraditional fishermen.Keywords: Puntius schawanefeldi, feeding habit, fish floating cage, KotoPanjang Dam

Abstract

Mimi merupakan organisme yang mendiami daerah Muara Sungai Paluh Sebilang. Namun informasi tentang mimi di daerah tersebut belum ada. Untuk memahami/mengetahui jenis mimi yang ada di muara sungai Paluh Sembilang,  penelitian ini telah dilaksanakan pada bulan April 2019. Daerah pengambilan sampel berada di sekitar pantai dan muara sungai Paluh Sembilang. Pengambilan sampel mimi dilakukan setiap hari selama dua minggu. Mimi ditangkap menggunakan mini trawl dengan mesh size 50 mm atau 2 inch dan mimi yang berada di pantai dapat di pungut langsung menggunakan tangan. Karakteristik morfometrik dan meristik mimi dianalisis secara deskriptif. Sampel mimi kemudian diidentifikasi. Terdapat 138 ekor  mimi (67 jantan dan 71 betina). Spesies mimi yang ditemukan terdiri dari dua spesies, yaitu Tachypleus tridentatus (61 Jantan dan 67 betina) dan Carcinoscorpius rotundicauda (6 Jantan dan 5 betina). Masing-masing dari setiap spesies memiliki karakter morfologi yang berbeda. T. tridentatus memiliki ukuran tubuh besar (33,08-34,89 cm) dengan warna abu-abu kehijauan. Sedangkan C. rotundicauda memiliki ukuran tubuh kecil (27,38-25,8 cm) dengan warna hijau tua hingga coklat kehijauan. Pola pertumbuhan relatif menunjukkan bahwa pertumbuhan jantan lebih cepat daripada betina.

Abstract

Changing in photoperiod duration will affects the physiology of fish in general. A study aims to understand the effects of photoperiod manipulation towards C. gariepinus morpho-anatomy and growth was conducted on March–May 2018. The fishes were reared in fiber tanks (140 x 60 x 40 cm) that was filled with water and completed with a circulatory system. Treatments applied were Control (natural photoperiod), 24G (24 hours dark), 18G6T (18 hours dark and 6 hours light), and 6G18T (6 hours dark and 18 hours light). The fishes were sampled once/14 days, 4 fishes/ aquarium/sampling. Parameters measured were length-weight relationship, condition factor, hepatosomatic index (HSI), viscerasomatic index (VSI), absolute length and weight, food conversion ratio (FCR), gonad development and body protein/fat. Results shown that photoperiod manipulation affects C. gariepinus morpho-anatomy and growth. The highest growth parameters and morpho-anotomy index were found in fish reared in 18G6T. By the end of the experiment, the b value of   length-weight relationship was 3.3205, absolute weight and length were 86.70 g and 17.23 cm, condition factor was 0.84, VSI was 25.31%, HSI was 11.42%, FCR was 1.43, and body protein and fat was 48.40% and 50.38%. In the fish reared in 24G treatment, b was 1.9262, 52.13 g BW and 14.19 cm SL, condition factor was 0.80, VSI was 23.30%, HSI was 9.38%, FCR was 2.47, and body protein and fat was 48.08% and 49.53%. In the fish reared in 6G18T, b was 2.6903,49.45 g BW and 13.79 cm SL, condition factor was 0.79, VSI was 23.30%, HSI was 6.80%, FCR was 1.91, and body protein and fat was 46.64% and 49.00%. Fish reared in natural photoperiod (control) shown the lowest results b was 2.0418, 51.68 g BW and 14.21 cm SL, condition factor was 0.79, VSI was 19.58%, HSI was 6.96%, FCR was 2.20, and body protein and fat was 43.95% and 47.77%.Early developing gonad (1st maturity stage) was only found in fish reared in 18G6T.

Abstract

Rearing Pangasius hypopthalmus under short manipulated photoperiod is able to improvethe growth of that fish, but the water quality of those rearing tanks were poor as there wasno phytoplankton to reduce the organic materials. By using the biofloc system, the organicmaterials might be processed and the water quality might be maintained. To understand thewater quality of P. hypopthalmus reared in the tanks with manipulated photoperiod andbiofloc system has been conducted in June to august 2020. Sampling DO and BOD5 wascarried out 4. Results shown that the DO of tanks with biofloc system was higher (11.814.49mg/L)thanthatofthetankswithoutbioflocsystem(11.81-7.68mg/L).ThewaterinthetankswithbioflocsystemalsoshownbetterresultsonBOD5(4.28-7.68mg/L).Inthetankswithout the biofloc system, the water quality parameters were as follows BOD5(4.28-35.22 mg/L). Based on data obtained, it can be concluded that the application ofbiofloc system is effective to maintain the water quality in the rearing tank of P.hypopthalmus treated with short photoperiod.

Abstract

In recent years, many net cages for aquaculture activities, especially for culturing Wallago leeri and Mystus numerus are placed along the Kampar River, especially in the Buluhcina Village. The remain of fish feed, namely rotten chicken flesh have polluted the water. This study aimed to identify the cage culture profile; to analyze the feasibility of the business and the carrying capacity of the environment. This research was conducted in August 2016 – March 2017. There are three observation stations,  Station 1 (before the cage area), Station 2 (the cage area) and Station 3 (after the cage area). Sampling was conducted once. The length of the river is 1.4 Km and 594 single unit net cages are placed along 1,2 Km river. Among the cages, 570 units (96% )are used to the culture of W. leeri,  19 units (3.2%) for M. numerus and the rest, 3 units are for rearing Pangasius sp. and Oreochromis niloticus (1 unit). The carrying capacity of the waters is 496.1 tons/year. The current annual production of W. leeri is 228 tons/year, it is less than the maximum potency.  It is predicted that the culture can be increased by 258.5 ton/year or 646 cages. The recent RCR value is 1.120, indicates that this business is profitable and it could be continued.

Abstract

The palm oil industry liquid waste is rich in organic materials and thus it can be used as media to grow Chlorella sp. This algae needs organic materials for growing, and it may decrease the organic material contents in the waste. To understand the best concentration of palm oil industry liquid waste to grow that algae, the chemical composition of the algae reared in different concentration of waste, and to understand the organic materials decrement in the waste, a study has been conducted in April – May  2019. There was a CRD applied. The waste was mixed with aquadest in   5 different concentration, namely    P1 (0%), P2 (15%), P3 (20%), P4 (25%), dan P5 (30%). Results shown that the best algae population was in the   P4 (4.64 x 106 cells/mL), the best biomass was in P3 (0.77 gr/L) in the 12nd day culture.  The P0 provide the best results on fat (12.5%) and carbohydrate (24%) but shown the lowest of protein (16%), DO (1.10 mg/L) and chlorophyll-a (0.140 mg/L) and provide the worst CO2 content (8.77 mg/l). P3 shown the highest content of protein (45%).   P4 shown the highest chlorophyll-a concentration (0.403 mg/L) and O2 concentration (9.94 mg/L) and the lowest CO2 (2.75 mg/l). The P4 also shown the best result in decreasing organic materials content. Nitrate reduced, from 14.3 mg/L into 3.1 mg/L, while Phosphate reduced, from    1.87 mg/L to 0.33 mg/L respectively. In all treatment, the water temperature ranged from 280C to 300C and the pH was   6.33 – 9.50.

Abstract

Abstract The Sail  River and Kampar Kiri River have different ecosystems characteristic and it may be reflected in the otolith’s growth ring patterns in the otolith of fish living in those areas. A research aims to understand the growth pattern present in the otolith of Pangasius polyuranodon. The fish were caught using nets and bamboo trap, once/week. There were 119 fishes (50 fishes from the River Sail and 69 fishes from Kampar Kiri River). The otoliths (sagita) were removed and processed following Windarti (2017). Growth  rings pattern was studied using a binocular microscope. The otolith in the Sail River length was 1- 2.175 mm and their weight was 0.0019-0.0075 mg. Whereas in the  Kampar Kiri River  length was 2-3.25  mm andtheir weight 0.0030-0.0267 mg. The  distance between the nucleus and the first dark ring was varied  from the Sail River (0.02-0.75mm) and Kampar Kiri River (0.025-0.75 mm). Results shown that the maximum number of dark ring in the otolith of fish living in the Sail River was 3, while that of the fish from the Kampar Kiri River was 4. Water quality in the sampling area was good and it may be suffcient to support  the life of Pangasius polyuranodon.   Keywords: Dark Ring, Otolith, Growth Pattern, Sagita

Abstract

AbstractOmpok hypophthalmus is freshwater fish that inhabit the Tarai River. That fish has high economic value, and it is more than Rp 60.000/kg. Information on biological aspects of this fish, including morphometric, meristic, and growth patterns, however, is rare. To understand the morphometrical, meristical characteristics and growth pattern of this fish, a research had been conducted from April-June 2018. There were 78 fishes(183-56 mm SL dan 45,32-1.23 gr BW) captured from the river. There were 25 morphological characteristics measured and 6 meristical characteristics counted. There were 7 morphometrical characteristic differences between male and female. In female fish, distance between ventral fin to the base of anal fin, height of dorsal fin, distance anal fin to the base of caudal fin, height ventral fin, and length of base caudal finare longer than those of the male, but male has longer distance mouth to the eye, and length of pectoral fin than female.The meristical characteristics were as follows: D.4, P.I.13-15, V.6-8, A.63-82, C.17-19. The length-weight relationship shown that the growth of male and female was isometric. Keywords:Sheatfish, Isometric, Morphological Characteristics, Meristical      Characteristic
