<![CDATA[The aim from this study is to find out the addition of natural feeds of Daphnia sp. that given of fish flour to the growth performance and survival rate of osphronemus gouramy larva. this study was conducted on July – August 2019 in Freshwater Aquaculture Development (FAD) Natar, east Lampung. The experimental method was used Complete Random Design (CRD) which 4 treatments and three replications on each. The treatments applied in this study were whithout fish meal feed (control), fish meal 2 gram, fish meal 4 gram and fish meal 6 gram. The highest protein content of the proximate test result is found in Daphnia sp. with dose 6 gram that containt of protein 7,64% and the lowest was found in whithout fish meal feed (control) containt of protein 4,58%. The results shiwed that Daphnia sp. those fed with fish meal were significantly different or had on effect on growth performance gouramy larvae, but had no effect on survival rate of gouramy larvae.]]>

<![CDATA[Disease in tilapia is caused by Aeromonas hydrophila. The disease has an effect on reduction of production cultivation and economic losses. The control efforts taken are to improve the non specific immune response in tilapia cultivated with biofloc system and probiotics against bacterial infection of Aeromonas hydrophila. This study aims to determine effect the non specific immune response in tilapia cultivated with biofloc system and probiotics against bacterial infection of Aeromonas hydrophila infection. The design used in this study completely randomized design with four treatments, control, biofloc, probiotics in feed and a combination of feed probiotics and biofloc. The parameters observed included total leukocytes, differential leukocyte, survival rate, relative percent survival, and water quality. The results showed that cultivated tilapia with bioflok, probiotics, and a combination of both provides a significant immune response to the parameters of total leukocytes and survival rate compared to control and immune response increases after injected bacteria Aeromonas hydrophila.]]>

<![CDATA[The mechanism of temporary upwelling and downwelling in the southern coast off Makassar Strait, Indonesia is determined not only by the wind-driven coastal during southeast monsoon (SEM) and northwest monsoon (NWM) but also by meeting of two current systems based on previous research. During SEM, water mass of the Flores Sea in eastern area meets the throughflow water coming from northern of Makassar Strait and flow together to Java Sea and this causes upwelling occur. But during NWM, water mass of the Java Sea western area meets the through flow water and flow together to southern cost of Celebes Island and causes downwelling occur. The first mechanism is well proven but the second one need more investigation.Twenty years of data result obtained from numerical simulation over the Makassar Strait and adjacent waters are used to describe the seasonal characteristic and mechanism of upwelling in this region. The 3D baroclinic ROMS (Regional Ocean Model System) from Rutgers version was simulated from 1995 to 2014.The climatological results show the existing of upwelling and downwelling clearly identified by the decreasing or increasing of sea surface temperature ± 2ºC and also increasing or decreasing of surface salinity ±0.5 Psu compared by surrounding waters. The evidence of upwelling starts on June, maximum intensity in August and disappears on September following the easterly wind during southeast monsoon. But downwelling start on December, maximum intensity in January and disappears on February. The mixed layer depth becomes shallow and there is an uplift water from the thermocline to the surface at the upwelling occur, but when downwelling occur the mixed layer depth becomes deeper. The instability of water column was detected from the Brunt-Väisälä frequency (N2) and Richarson number (Ri). By calculating the vorticity and investigate the current circulation we detect the eddy formation in southern part of the Celebes Island at Java Sea and Flores Sea and suggested due to the meeting of current system. We found the Ekman transport is moving to the southern direction offshore of Celebes Island and produces the upwelling during SEM. But when NWM occur, Ekman transport is moving to the northern direction from offshore to the Celebes Island and produce downwelling.]]>

<![CDATA[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.]]>

<![CDATA[Kendal District coastal and marine areas have considerable fishery potential. The potential of these fisheries can be explored well by taking into account several supporting factors. One of the factors that influence the level of fish existence is the condition of water fertility. The parameter used to determine the level of water fertility is to determine the chlorophyll-a content produced by phytoplankton. The development of remote sensing technology makes it possible to detect the presence of chlorophyll-a in waters with a large coverage and low cost. This study aims to identify the value of concentration and distribution of chlorophyll-a by using satellite landsat 8 imagery in four seasonal conditions, namely the west to east transition season, east season, east to west transition season and west season. The transition from West to East the minimum value of chlorophyll-a concentration is 1,106 mg / m3 and the maximum value is 2,700 mg / m3. East to West transition season has a minimum value of chlorophyll-a concentration of 1,539 mg / m3 and a maximum value of 2,700 mg / m3. The East Season has the same minimum and maximum values as the transition season from West to East but the amount of distribution differs, the West Season has a minimum value of chlorophyll-a concentration in this season of 1,318 mg / m3 and the maximum value of 2,700 mg /m3.]]>

<![CDATA[Laundry activities produce waste laundry detergent. Laundry detergent waste toxicity tests need to be done research on test animals Patin (P. hypophthalmus) to determine the effect of surfactant materials on water quality and fish mortality rate Patin. This study aims to get the effect of acute and sub-chronic toxicity of waste and get the laundry detergent safe doses for seed growth Patin. The method used in this study is an experimental method by using a completely randomized design (CRD) with four treatments and three replications of each treatment. Preliminary test results obtained under the threshold value of 100 ml/L and the threshold value above 1000 ml/L. Acute toxicity tests using probit anlisis LC50-96 values obtained laundry detergent waste hours on 397 ml/L. In sub-chronic toxicity test showed the best concentration of laundry detergent waste contained at a concentration of 3.97 ml/L with an absolute weight of 1.15 grams, specific growth rate of 1.48% and 90% fish survival. Value safe biological limits in this study was 3.97 ml/L. It can be concluded that the difference in concentrations of laundry detergent waste significant effect (p<0.05) to Patin. The concentration of 3.97 ml/L is safe and not harmful to the aquaculture process Patin (P. hypophthalmus) using common water resources.]]>
