Peristiwa overfishing semakin marak terjadi di beberapa wilayah perikanan Indonesia akibat penggunaan alat tangkap yang merusak (destruktif). Jika hal ini terus dilakukan, maka kelestarian sumberdaya dikhawatirkan akan semakin menurun. Maka dari itu dibutuhkan strategi agar usaha perikanan tangkap ramah lingkungan secara ekologi dengan cara mengidentifikasi alat tangkap berdasarkan kriteria Code of Conduct for Responsible Fisheries (CCRF). Tujuan dari penelitian ini adalah untuk menganalisis alat tangkap ramah lingkungan di PPI Celong berdasarkan Sembilan kriteria CCRF. Metode penelitian yang digunakan adalah deskriptif mengenai alat penangkapan ikan yang ramah lingkungan di Pangkalan Pendaratan Ikan (PPI) Celong pada bulan Desember 2017 dengan wawancara dan observasi lapangan. Responden diambil secara sensus sebanyak 121 orang. Hasil analisis ramah lingkungan menghasilkan skor 17,87 pada arad, 27,44 pada trammel net, dan 28,40 pada gill net. Kesimpulan yang diperoleh dari penelitian ini adalah status alat tangkap arad tidak ramah lingkungan, trammel net ramah lingkungan, dan gill netsangat ramah lingkungan. Arad termasuk dalam kategori tidak ramah lingkungan karena cara pengoperasiannya yang tidak selektif dan merusak dasar perairan.

Ekosistem mangrove terdapat di seluruh pantai maupun pulau-pulau kecil Indonesia yang terpengaruh oleh pasang surut. Kajian pola sebaran, indikator kualitas lingkungan dan ekologi komunitas mangrove Pulau Tunda dilakukan pada bulan Januari 2014 dengan tujuan untuk mengetahui pola sebaran, indikator kualitas lingkungan dan ekologi komunitas mangrovenya. Sampel mangrove diambil menggunakan transek garis dan plot yang ditarik dari titik acuan (tegakan mangrove terluar) serta tegak lurus garis pantai sampai ke daratan. Kemudian transek garis tersebut dibuat petak-petak contoh (plot) yang berukuran 10 x 10 m2 untuk kategori pohon dan di dalam ukuran 10 x 10 m2 dibuat plot berukuran 1 x 1 m2 untuk kategori semai. Pola penyebaran mangrove Pulau Tunda dianalisis berdasarkan indeks Morisita. Sementara kualitas lingkungan hutan mangrove dianalisis menggunakan tutupan pohon, tutupan semai dan jumlah jenis semai yang ditemukan. Kemudian ekologi komunitas mangrove Pulau Tunda dianalisis berdasarkan indeks keanekaragaman, dominansi dan keseragaman. Hasil penelitian menunjukan bahwa pola penyebaran mangrove Pulau Tunda tergolong beraturan (regular), dimana terjadi interaksi negatif antar individu dalam memperebutkan ruang, unsur hara maupun cahaya matahari. Selain itu, kondisi hutan mangrove Pulau Tunda masih tergolong baik dengan tingkat kualitas lingkungan vegetasi mangrove 73.74%, keanekaragaman dan dominansi mangrovenya tergolong rendah (1.20 dan 0.52) dan keseragamannya tergolong labil (0.60). Mangrove ecosystems are found throughout the coast and small islands of Indonesia which are affected by tides. Distribution pattern studies, environmental quality indicators and the ecological mangrove community of Tunda Island were carried out in January 2014 with the aim to determine distribution patterns, indicators of environmental quality and ecology of the mangroves community. Mangrove samples were taken using line transects and plots drawn from reference points (outer mangrove stands) and perpendicular to the coastline to the mainland. The line transect is made of plots of sample size 10 x 10 m2 for the category of trees and in a size of 10 x 10 m2 a plot of 1 x 1 m2 is made in the seedling category. The pattern of distribution of mangroves of Tunda Island was analyzed based on the Morisita index. While the environmental quality of mangrove forests was analyzed using tree cover, seedling cover and number of seedlings found. The ecology of the Tunda Island mangrove forest community was analyzed based on the diversity index, dominance and uniformity. The results showed that the pattern of mangrove distribution of Tunda Island was regular, where there was a negative interaction between individuals in fighting over space, nutrients and sunlight. In addition, the condition of the Tunda Island mangrove forest is still relatively good with the level of environmental quality of mangrove vegetation 73.74%, the diversity and dominance of mangroves are relatively low (1.

Perairan Muara Sungai Sayung terletak di wilayah Kabupaten Demak sebelah barat. Perairan ini telah dipengaruhi oleh berbagai aktivitas manusia yang menyebabkan terjadinya penurunan kualitas perairan. Bakteri Coliform merupakan bakteri gram negatif yang berbentuk batang dan tidak membentuk spora. Bakteri ini merupakan bakteri indikator terjadinya pencemaran perairan maupun indikator keberadaan bakteri patogen lainnya. Perhitungan total bakteri Coliform perlu dilakukan untuk mengetahui adanya pencemaran limbah organik yang terjadi di Perairan Muara Sungai Sayung, Morosari, Demak. Tujuan dari penelitian ini adalah untuk mengetahui kelimpahan total bakteri Coliform, dan status perairan di Perairan Muara Sungai Sayung, Morosari, Demak. Penelitian ini juga bertujuan untuk mengetahui hubungan dari jumlah total bakteri Coliform dengan bahan organik terlarut dan oksigen terlarut (DO). Pelaksanaan penelitian ini dilakukan pada bulan Mei 2018. Metode yang digunakan dalam penelitian ini adalah metode survei dan teknik pengambilan sampel menggunakan metode random sampling yang dilakukan pada lima stasiun. Hasil penelitian menunjukkan bahwa kelimpahan rata-rata total bakteri Coliform yang diperoleh berkisar antara 4 x 103 – 550 x 10 3/100ml. Kelimpahan rata-rata total bakteri Coliform yang diperoleh pada setiap stasiun menunjukkan bahwa kandungan total bakteri Coliform telah melebihi baku mutu air menurut Keputusan Menteri Lingkungan Hidup Nomor 51 Tahun 2004. Keberadaan total bakteri Coliform memiliki hubungan yang lemah dengan kandungan bahan organik terlarut, sedangkan keberadaan total bakteri Coliform memiliki hubungan yang cukup dengan oksigen terlarut (DO) di perairan Muara Sungai Sayung Morosari, Demak. Sayung River Estuary is located in the western part of Demak Regency. This estuary has been affected by various human activities which have led to a decline in water quality. Coliform bacteria are a gram-negative bacteria that are rod-shaped and do not form spores. This bacterium is an indicator bacteria of water pollution and an indicator of the presence of other pathogenic bacteria. Total Coliform bacteria calculation needs to be carrid out to find out if there any contamination of organic waste in Sayung River Estuary, Morosari, Demak.. The purpose of this research was to determine total abundance of Coliform bacteria, water quality in Sayung River Estuary, Morosari, Demak and relationship between the total abundance of Coliform bacteria with dissolved organic matter and dissolved oxygen (DO). This research was carried out in May 2018. The method that used in this research were survey method and the sampling technique was random sampling method in five stations.

Based on the results of the research, the abundance of phytoplankton at high and low tides ranged between 6.375 - 13.725 cells/l and chlorophyll-a concentrations at high and low tides ranged between 0,126 – 1,392 mg/m3. The value of diatom quotient is 1,533 which means that the waters of study area belong to the eutrophic category. The abundance of phytoplankton and concentrations of chlorophyll-a at high tide is higher than at low tide. Both show a high level relationship.","PeriodicalId":193095,"journal":{"name":"SAINTEK PERIKANAN : Indonesian Journal of Fisheries Science and Technology","volume":"162 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131717272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Peningkatan konsumsi ikan air tawar di Kota Kupang menstimulasi para pembudidaya ikan untuk berlomba-lomba meningkatkan produksi usahanya. Mengingat cara budidaya ikan yang dilakukan di Kota Kupang adalah dengan padat tebar tinggi dan tanpa pergantian air, maka dapat menyebabkan kualitas media air menjadi buruk karena adanya dekomposisi dari hasil sisa pakan sehingga memungkinkan perkembangbiakan mikroba patogen. Penelitian ini bertujuan untuk mengetahui gambaran histopatologi pada organ insang, hati dan usus ikan lele di Kota Kupang. Ikan lele sebanyak 100 ekor yang diambil dari Pasar Oeba kemudian diukur berat dan panjang serta diamati kondisi morfologinya. Organ insang, hati dan usus diambil dan dilakukan fiksasi menggunakan larutan formalin 4%. Preparasi histopatologi dan analisisnya dilakukan di laboratorium. Spesimen diwarnai dengan menggunakan hematoxylin dan eosin. Hasil penelitian menunjukkan adanya abnormalitas dan kerusakan jaringan pada organ-organ tersebut. Abnormalitas yang terjadi adalah adanya sungut patah, sirip dada panjang sebelah, sirip perut besar sebelah, jumlah sirip dada dan perut hanya satu, ukuran hati kecil, hati terdapat bercak kuning, hati berumbai dan pucat. Kerusakan jaringan organ insang yang terjadi adalah telangeaktasis, nekrosis, edema, hiperplasia, perhimpitan lamela sekunder, fusi, hemoragi, kongesti dan jaringan yang lepas. Sedangkan pada hati adalah fibrosis, hemoragi, kongesti, terbentuknya vakuola-vakuola, adanya degerasi lemak, kumpulan makrofag yang ditandai dengan adanya MMC, hiperplasi, piknotik dan nekrosis. Dan pada usus adalah nekrosis, edema dan hemoragi. The enhancement of freshwater fish consumption in Kota Kupang has stimulated fish farmer to increase their production. The cultivation’s system of fish conducted in Kota Kupang is carried out with high density and whithout water circulation wich decreases water quality caused leftover feed decomposition so as that possible to pathogenic microbes breeding. The aim of this research was observe the description of gill, liver and gut’s histopathology of Catfish in Kota Kupang. One hundred Catfish was taken from Oeba Market which be measured the weight, length and observation of morphological condition. Gills, liver and gut was taken and fixatived with 4% of formalin. Histopathological preparation and their analysis was done in laboratory. The specimens were stained with hematoxylin and eosin. The result of this research showed abnormalities and tissue damage on the organs. The abnormalities showed the presence of flesh grows near the reproductive organ, the size of pectoral vins and ventral vins were not same, only one was pectoral vins and ventral vins, small liver, yellow liver, tassel-shaped and pale liver. The gill’s damage tissue was telangeaktasis, necrosis, edema, hyperplasia, coincide of secondary lamela, fussion, hemorage, congestion and lifting tissue. Liver’s damage was fibrosist, hemorage, congestion,vacuolas, fat degeneration, melano
库邦市淡水鱼类消费量的增加刺激了渔业加紧竞争，促进了渔业的努力。由于在库彭市养殖鱼类的方法非常密集，而且没有径流，这可能会导致由于制成品的分解而降低水质，从而允许微生物病原体的生长。这项研究的目的是确定库邦市鲶鱼的鳃、肝脏和肠的组织性病理特征。来自Oeba市场的100条鲶鱼被测量了重量和长度，并被观察到形态状态。鳃、肝脏和肠道器官被提取并通过使用4%的福尔马林溶液进行固定。在实验室进行组织组织和分析。用血液素和eosin染色标本。研究表明这些器官有异常和组织损伤。它们的异常之处在于，它们的触角断了，长长的胸鳍，大腹鳍，只有一个胸鳍和腹部的数量，鳃组织的损伤包括坏死、坏死、水肿、高生、中度、融合、出血、收缩和组织脱落。肝脏是纤维化，出血，结膜，液泡的形成，脂肪去角质，以MMC、多动症、脑膜炎和坏死为特征的巨噬细胞。肠道内坏死、水肿和出血。库邦市新生鱼类的加水捕捞刺激了它们的生产。库邦市受保护的鱼类保护系统的高密度和惠特豪斯受污染的水集中集中在受污染的微育种中。这项研究的目标是对库邦市鲶鱼的描述、肝脏和内脏的结肠科。数百只鲶鱼来自计算体重、length和观测形态变化的市场。吉尔斯，肝脏和肠子被氟化4%的甲醛切除并固定。组织病原和分析正在实验室进行。他们被注射了血液素和eosin。这项研究的结果表明，有机生物有异常的斑点和组织损伤。非正常的行为表现为在生殖器官附近长出的肉，胸肌和腹侧文斯的大小是不一样的，只有一个是胸状文斯和腹侧文斯，小肝脏，黄色肝脏，蛋黄形状和苍白的肝脏。吉尔的和平组织被诊断为坏死、坏死、水肿、高血浆、融合、血液病、收缩、收缩组织。肝脏损伤是纤维性的，血肿的，收缩的，真空的，真空的，脂肪退化的，美拉诺宏法格中心，高胎盘，坏死。内脏的坏死是坏死、水肿和血肿。keras, R. mucronata, L. racemosa和S. caseo房间与胃波达关系密切，N. planospira和M. puella。
