Eel Resource Management in Indonesia

According to FAO (1997 ) understanding of fisheries management is the integrated process of information collection , analysis , planning , consultation , decision -making , resource allocation and implementation of a set of rules in the field of fish resources in order to ensure productivity , and goal achievement other fisheries . The fishery management encompasses many aspects including fish resources , habitat / environment , and humans as well as various internal factors ( Widodo and suadi, 2006) . Production and fishery potential is limited by a number of factors , namely the consideration of biological , ecological and environmental considerations , social considerations and kelembangan cultural , and economic considerations . Considerations include smberdaya living marine biology capable of renewing themselves through a process of growth , the length and mass ( weight ) of individuals in addition to the increase of the population or community through reproduction ...

Optimum Temperature for Crustacea

Suhu merupakan salah satu faktor abiotik yang mempengaruhi aktifitas nafsu makan, konsumsi oksigen, sintasan, pertumbuhan dan moultingcrustacea (Villareal, 2003). Rustam (1989), mengemukakan bahwa suhu yang baik untuk kehidupan kepiting bakau adalah 24 - 32oc Suhu adalah faktor ekstrinsik yang paling penting yang mempengaruhi durasi intermolt, dengan pengaruh yang sangat umum bahwa kenaikan suhu yang menyolok memperpendek intermolt. Sebuah pilihan dari sekian banyak contoh dari larva dan perkembangan postlarval tercantum di bawah ini, bersama-sama dengan kisaran suhu   di mana   diamati. Daphnia spp. (MacArthur and Baillie, 1929)                       8°-28°C Cypj-inotus sp. (Kurata, 1962)                              ...

Viability of Aeromonas hyrdophila on Glycerol Broth during Freezing

Aeromonas Hydrophyla is one of the bactery that damage the cultivation of fish.   Storage / preserving collection of bactery is very inportant, particularly of strain standard is used in diagnose a fish disease. The purpose of this experiment is to know the concentration of preserving media effective and efficient from storage A. hydrophila in the freezer -20˚C for 4 months. The design of experiment that used is complete random design (RAL) with treatment and each treatment repeated for 4 times. Whole treatment will be saved on freezer -20˚C and to do observation data of density population week in 0, 2, 4, 8, 12 and 16. The data of density population is used as parameter viability (%) then it is analyzed by using variable analysis (ANOVA) and if there is real different, will be done the next experiment use meters DUNCAN (Steel & Torrie, 1995). The parameter addition eyes in qualitative is test biochymis reaction and morfologi. The variable analysis ANOVA result shows tha...
