This zooplankton is widely favored by marine fauna larvae because of its small size can fits well with various larval mouth; thus, it is easily preyed by larvae. This study aimed to determine the variation of rotifer B. rotundiformismorphometry if cultured with different feed at 40 ppt. The use of 40 ppt salinity is expected to provide a variable morphometric size because B. rotundiformishas a polymorphism property. Microalgae used as feed for rotifer B. rotundiformiswere Prochloronsp. and Nanochloropsis oculata. Microalgae were cultured with Hirata medium. In the early stages, B. rotundiformiswas cultured at optimum temperature (28 ºC) and salinity 20 ppt, then it was cultured at salinity 40 ppt. Salinity adaptation was done by raising the salinity of the medium by 2 ppt every two days in a 10 ml reaction tube containing 10 individuals. After adaptation, B. rotundiformiswas transferred in a 1000 ml container with a density of 50 individuals. For the morphometric aspect, the total length, the length of the lorica, the width of the lorica and the anterior width were measured. The result showed the morphometric of rotiferB. rotundiformisfed with microalgae Prochloronsp. at 40 ppt salinity was smaller than that of the rotifer fed with N. oculata. Based on that finding it can be concluded that B. rotundiformis fed with Prochloronsp. at a salinity of 40 ppt has the potential to be developed as feed for fish larvae. Further investigations on how to accelerate the cultivation of microalgae Prochloronsp. as feeding for B. rotundiformisare needed.RotiferBrachionus rotundiformismerupakan golongan zooplankton yang digunakan sebagai makanan bagi larva ikan. Zooplankton ini banyak disukai oleh larva fauna laut, karena ukurannya kecil yang cocok dengan berbagai bukaan mulut larva. Penelitian ini bertujuan untuk mengetahui variasi morfometri rotifer B. rotundiformis, jika dikultur pada salinitas yang tinggi (40 ppt) dengan pemberian pakan berbeda. Penggunaan salinitas 40 ppt diharapkan bisa memberikan ukuran morfometrik yang bervariasi, karena rotifer jenis ini memiliki sifat polimorfisme. Alga mikro yang digunakan sebagai pakan adalah Prochloronsp. Dan Nanochloropsis oculata.Alga mikro tersebut dikultur dalam media Hirata. Pada tahap awal, B. rotundiformisdikultur pada suhu optimum (28 ºC) dengan salinitas 20 ppt; kemudian, dikultur pada salinitas 40 ppt. Adaptasi salinitas dilakukan dengan menaikkan salinitas medium sebanyak 2 ppt setiap dua hari dalam tabung reaksi berukuran 10 ml, yang berisi 10 individu. Setelah diadaptasikan, rotifer dipindahkan ke wadah berukuran 1000 ml dengan kepadatan sebanyak 50 individu dan dikultur pada salinitas 40 ppt.

This requires that fishermen have the motion or power that can determine and influence the behavior of groups and their members in achieving their goals effectively. Fishermangroups should always be dynamic in running fishing business. This study aims to 1) analyze the factors that affectthe dynamics of traditional fishing groups in the coastal reclamation area of Manado City, and 2) determine the dynamics model of traditional fishermen groups in the coastal reclamation area of Manado City. This research wasconducted using survey method. F test statistics wasused for mixedinfluence test and t-test statistic for partial test. Multiple linear regressions was conductedto describe the dynamics of traditional fishermen group in the coastal reclamation area of Manado City. The result of this research concluded that internal (X1) and external (X2) factors together or partially hasan effect on dynamics of traditional fisherman group of coastal reclamation area of Manado City. Partially, internal sub factor (education level and experience of fishing effort) and external sub factor (the availability of capital aid and information availability) have real effect ondynamics of traditional fisherman group of coastal reclamation area of Manado City.

Hal ini mengharuskan nelayan memiliki gerak atau kekuatan yang dapat menentukan dan mempengaruhi perilaku kelompok dan anggota-anggotanya dalam mencapai tujuan secara efektif. Kelompok nelayan harus selalu dinamis dalam menjalankan usaha penangkapan ikan. Penelitian ini bertujuan untuk 1) menganalisis faktor-faktor yang mempengaruhi dinamika kelompok nelayan tradisional di kawasan reklamasi pantai Kota Manado, dan 2) menentukan model dinamika kelompok nelayan tradisional di kawasan reklamasi pantai Kota Manado. Penelitian ini mengunakan metode survey. Statistika Uji-F digunakan untuk uji pengaruh secara bersama-sama dan Statistika Uji-t untuk uji parsial. Regresi linear berganda dilakukan untuk menggambarkan persamaan dinamika kelompok nelayan tradisional di kawasan reklamasi pantai Kota Manado. Dari hasil penelitian dapat disimpulkan, bahwa faktor internal (X1) dan eksternal (X2) secara bersama-sama maupun parsial berpengaruh nyata terhadap dinamika kelompok nelayan tradisional. Secara parsial sub-faktor internal (tingkat pendidikan dan pengalaman usaha penangkapan ikan) dan sub-faktor eksternal (ketersediaan bantuan modal dan ketersediaan informasi) berpengaruh nyata terhadap dinamika kelompok","PeriodicalId":106687,"journal":{"name":"AQUATIC SCIENCE & MANAGEMENT","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128999631","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}
