Abstract

This study is to determine the level of land suitability as well as assessing the extent to which the potential of land resources can be utilized for the cultivation of mangrove crabs. The purpose of this research is to know the level of land suitability based on physical and chemical parameters for the cultivation of mangrove crab in the pond area in Degayu Village. This research was conducted on 4 until 9 June 2018 at 4 ponds in Degayu Village. Water parameters measured are temperature, salinity, water pH, DO, ammonia, nitrate, phosphate, soil texture, soil pH. The feasibility analysis of pond land is done by using Scoring Method with 3 values of feasibility class interval that is very suitable (S1), according (S2), not appropriate (S3). The result from 4 point of pond station representing Degayu Subdistrict showed temperature value ranged from 31-34 ºC, salinity ranged between 18-28 ppt, water pH ranged from 6,3-7,9 ppm, DO ranged from 3.0-6,0 ppm, ammonia ranged from 0.1-0.3 mg/l, nitrate ranged from 1.4 to 1.8 mg / l, phosphate ranged from 1 -2 mg / l, soil texture was generally dominated by a mixture of clay / clay, sand, and dust and soil pH ranges from 7.0 -7.5. At station 1,3 gets S1 value (very suitable) while station 2,4a, and 4b got S2 value (accordingly). Pond in Degayu village has a category of appropriate feasibility class (S1) to support the activities of mangrove crab cultivation. Keywords: Crab, Land suitability, Water quality and soil parameters

Abstract

Shrimp vannamei (Litopenaeus vannamei) is a kind of shrimp that has important economic value in Indonesia, one of the inhibiting factors in increasing shrimp production is a disease caused by bacteria vibrio sp. This disease can cause a high death. This study aims to identify and quantify the number of Vibrio sp bacteria colonies in the hepatopancreas shrimp vannamei in ponds given probiotics, carried out in Sampang Tigo Ponds, Degayu –Pekalongan and Central Fish Ponds Brackish Water Aquaculture (BBPBAP), Jepara. This study was conducted on Monday 13 November 2017 to Wednesday April 25 2018. The study was conducted on a pond with a density of 100 and 116 tail / m3. The data of the research results were analyzed descriptively with the help of graphs and tables. The results showed that the sample of each plot of bacterial colonies exceeded the threshold, that is the average number of vibrio sp bacterial colonies on hepatopancreas shrimp T2 3,96 x 10 6 CFU/ml and T3 plots 1,46 x 10 6 CFU/ml followed by shrimp morphological changes that have clinical signs of vibrio sp bacteria, the state of unbalanced water quality supports the bacterialgrowth.

Abstract

The purpose of this research is to study the effect of substitution of fish meal with silage meal of chicken feathers on feed to protein digestibility, growth and survival rate of striped catfish (Pangasius hypopthalmus). The test fish used is catfish with an average weight of 2.31 ± 0.04 grams /fish. This research used experimental method with Completely Randomized Design, 5 treatments in triplicate. The treatments in this study were substitution of fish meal meal with different dose of chicken feather meal, namely A, B, C, D and E (0%; 25%; 50%; 75% and 100% silage meal of chicken feathers, respectively). Parameters observed included relative growth rate (RGR), feed conversion ratio (FCR), protein efficiency ratio (PER), Apparent Digestibility Coefficient of Protein (ADCP), and survival rate (SR) of catfish. The results showed that the substitution of fish meal with chicken feather silage meal was very significant (P <0.01) to RGR, FCR, PER, and ADCP, but no significant effect (P> 0.05) on SR of catfish. Dose 25% silage chicken feather meal in the feed is the best dose to improve the RGR and ADCP of catfish. Water quality during the study is still within a reasonable range for catfish culture.

Abstract

Kabupaten Batang merupakan salah satu wilayah minapolitan di pesisir pantai utara Jawa Tengah. Sebagai kawasan minapolitan banyak masyarakat Batang yang bermata pencaharian sebagai nelayan, sehingga banyak diketemukan Tempat Pelelangan Ikan (TPI) di wilayah ini. Tujuan dari artikel ini adalah untuk menyampaikan kajian mengenai studi eco-teknis keberadaan Tempat Pelelangan Ikan (TPI) di Kabupaten Batang, dengan harapan kedepan akan ada banyak konsep-konsep penelitian serta kebijakan-kebijakan yang bersifat konstruktif terhadap pengembangan Tempat Pelelangan Ikan (TPI) di Kabupaten Batang. Di Kabupaten Batang berdasarkan studi literatur terdapat 5 alat tangkap yang dominan digunakan oleh para nelayan tangkap, yaitu gill net, trammel net, bubu, cantrang, dan arad yang jumlahnya masing-masing lebih dari 100 buah. Masing-masing dari alat tangkap tersebut memiliki nilai B/C Ratio >1 (arad 1.70, trammel net 1.55, bubu 1.69, dan gill net 1.27) yang artinya sangat layak dan menguntungkan untuk digunakan. Sedangkan terkait dengan Tempat Pelelangan Ikan (TPI) sebagai fasilitas untuk kegiatan tata niaga nelayan, di Kabupaten Batang untuk sejumlah TPI seperti di Klidang Lor, Roban Barat, Roban Timur, Celong, dan Siklayu secara fasilitas kelima TPI tersebut dinilai sangat layak dan menguntungkan untuk mendukung kegiatan usaha perikanan tangkap yang dilakukan oleh nelayan. Selain itu ditinjau dari aspek sarana dan prasarana kelima TPI tersebut secara umum telah memiliki standar sarana dan prasarana seperti yang telah ditetapkan oleh Menteri Kelautan dan Perikanan dalam Kepmen KP No. 01/MEN/2007 tentang persyaratan jaminan mutu dan keamanan hasil perikanan pada proses produksi, pengolahan, dan distribusi.

Abstract

      AbstractThe  Maintenance  of mangrove crabs single  room system requires the  provision  of food  in quantity and good quality, cheap, on time and deliver high production value. One of the available food for  the  growth  of mangrove crabs in Central  Java is  the golden  apple  snail (Pomacea canaliculata), which has a protein content reached 51%. This study aims to determine the effect of feeding fresh golden apple snail with different doses on the growth and survival of mangrove crabs in  a single  room in  the pond system. The  study  consisted of five treatments fresh  golden apple  snail fresh feed at  a  dose  of 5.7,  9,  11 and  13%  / BW/day)  with  5 replications.  The experiment conducted at the beginning of mangrove crabs weigh between 80-100 g. Parameters measured include weight  gain during maintenance,  feed  efisiansi, survival and quality  of  the waters. The results showed, the highest weight gain observed in the treatment of 9% amounting to 92.2 g, while the lowest weight gain observed in the treatment of 5% amounting to 56.6 g. There was no difference in survival in each treatment feed, with the highest survival rate of 100%. The lowest feed  efficiency is  toun  the  treatment of  feed contained 13% of 41.61%.  During  the research, the parameters of qualities water in all treatments was within the range for the growth of mangrove crabs. Keywords: Scylla serrata, golden apple snail, growth, survival, feed efficiency

Abstract

Gift tilapia (Oreochromis sp.) Is one type of fish which are potential to be cultivated intensivelybecause tilapia gift has favorable properties, namely: rapid growth, eating all the food (omnivores),high tolerance to various environmental conditions, and resistant to disease attacks. Seeing the potential of the plant Azolla sp. which is a pest in agricultural land which is very abundant anduntapped by the community then the Azolla sp. used as a natural alternative feed on tilapia seedgift, because the high protein content and amino acid composition essensialnya complete. Thisresearch was conducted in August to September 2010, housed at the Laboratory of AquacultureFaculty of Fisheries University of Pekalongan. With the aim to determine the effect of feeding onthe growth of Azolla sp tilapia gift. The research was conducted based on completely randomizeddesign with 4 treatments and 3 replications. The treatments applied were given doses of naturalfood Azolla sp, ie A = 2%, B = 4%, C = 6%, and D = 8%. Results obtained from the study is oftreatment D showed the highest growth in average body weight with average seed weight 2.81 g,followed by treatment C, B and A, each with average seed weight 1.19 g, 1.71 g, 2.41 g Theanalysis showed that differences in the dose range of Azolla sp very real effect on the growth oftilapia seed gift. While the results of Orthogonal Polynomial analysis showed D treatment weresignificantly different with treatment C, B, A. The water quality of the media during the studywithin reasonable range, the temperature between 29-32 º C, pH ranged from 7.0 to 7.2 and DOranges from 3-5 ppt.Keywords: Azolla sp., alternative feed, Gift tilapia
