- "From ancient times, fishing has been a major source of food for humanity and a provider of employment and economic benefits to those engaged in this activity. The wealth of aquatic resources was assumed to be an unlimited gift of nature. However, with increased knowledge and the dynamic development of fisheries after the Second World War, this myth has faded in face of the realization that aquatic resources, although renewable, are not infinite and need to be properly managed, if their contribution to the nutritional, economic and social well-being of the growing world's population is to be sustained" (Fao Code of Conduct for Responsible Fisheries - Preface). Thus fishing has to be conducted in a responsible and sustainable manner because fish provides a vital source of food and, at the same time, fishing is closely connected to the environment because, if it is not properly practised can it cause irreparable damage. This work analyses the principle of precaution which was recognized as principle no. 15 in the Declaration of Rio on Environment and Development in 1992 and mentioned at the Conference on Biological Diversity. It represents one of the fundamental principles of the Fao Code of Conduct for Responsible Fisheries and Common Fisheries Policy (Regulation (EC) No 2371/2002 of 20 December 2002). States should apply a precautionary approach choosing the best measures and policy, taking into account the latest scientific evidence available. The aim is «to protect and conserve living aquatic resources, to provide for their sustainable exploitation and to minimise the impact of fishing activities on marine eco-systems.» (article 2 Regulation (EC) No 2371/2002).Parole chiave: scienza, protezione, precauzione, pesca, sviluppo.Key words: Science, Protection, Precaution, Fishing, Development.

West Of Ireland

After the 1989 sea trout collapse in the west of Ireland, the angling community (which includes private fishery owners) attributed the collapse to coastal salmon farms, but the salmon farming community linked the sea trout collapse to environmental factors. The contending parties raised issues which are assessed here through the literature on environmental protests and the sociology of science. This paper then provides an analysis of the sea trout dispute as a conflict between angling interests and fish farming interests over the legitimate use of aquatic resources in rural Ireland. By drawing upon interview data, and government and industry publications, it will show that the dynamics of the sea trout conflict delineates the sociocultural context of science in the disputing process, as well as the nature of social change in rural Ireland.

Kegiatan budidaya pada setiap prosesnya menghasilkan limbah yang dihasilkan dari sisa-sisa pakan dan kotoran yang berasal dari ikan budidaya, terutama budidaya Ikan Nila yang merupakan salah satu jenis ikan tawar yang sudah di budidaya secara komersial oleh masyarakat indonesia. Penelitian dilaksanakan pada Mei-Juni 2017 di Laboratorium Pengelolaan Sumberdaya Ikan dan Lingkungan, Departemen Sumberdaya Akuatik, Fakultas Perikanan dan Ilmu Kelautan, Universitas Diponegoro. Pada penelitian ini ditambahkan enzim pada pakan ikan, suatu enzim yang mengandung protease, lipase, amilase, pepsin, tripsin, dan kemotripsin dalam dosis yang sudah ditentukan untuk memaksimalkan proses pencernaan. Ikan Nila yang digunakan  berukuran 7-9 cm dipelihara di dalam akuarium dengan kapasitas 2 ekor Ikan Nila dalam 1 akuarium dengan volume air 9 l. Tujuan penelitian untuk mengetahui konsentrasi amoniak, nitrit, dan sulfida (H2S) dan membandingkan pengaruh pemberian enzim dengan konsentrasi yang berbeda didalam pakan terhadap konsentrasi amoniak, nitrit, dan sulfida (H2S). Metode yang digunakan adalah metode eksperimental skala laboratorium. Desain penelitian berdasarkan rancangan acak lengkap (RAL), dengan menggunakan lima perlakuan yaitu dengan perbedaan konsentrasi enzim. Setiap perlakuan dilakukan 3x pengulangan. Analisis data menggunakan uji two way anova. Hasil penelitian menunjukkan bahwa pemberian enzim dengan konsentrasi berbeda tidak berpengaruh nyata, lama waktu pemeliharaan berpengaruh nyata terhadap konsentrasi amoniak, dan sulfida, kombinasi dari keduanya tidak berpengaruh nyata terhadap konsentrasi amoniak, nitrit, dan sulfida. Cultivation activities in each process produce waste generated from the remnants of feed and feces from the fish cultivated, especially the cultivation of tilapia which is one type of fresh bonds that have been cultivated commercially by the people of Indonesian. The research was conducted in May-June 2017 at the Fish and Environmental Resource Management Laboratory, Aquatic Resources Department, Fisheries and Marine Science Faculty, Diponegoro University. The materials on this research are combining the fish feed with an enzime which contains protease, lipase, amylase, pepsin, trypsin, and chemotrypsin in prescribed doses to maximised the digestion process. Tilapia as research object has length of 7 to 9 cm and its kept in an aquarium with capacity (water volumes) of 9 ls which contains of 2 tilapias. The purposes of this research are to know the concentration of ammonia, nitrite and sulfide (H 2 S) in and to compare the effect of the enzyme provision with different concentration in fish feed with the concentration of ammonia, nitrite and sulfide (H 2 S). This research used laboratory-scale experimental method. The study design was based on Complete Randomized Design (RAL), using five treatments with different enzyme concentrations. Each treatments was done by three repetitions. The data was analysed using two-way ANOVA test. The results showed that enzyme with different concentration had no significant effect, maintenance time had significant effect on ammonia concentration, and sulfide, the combination of both did not significantly affect the ammonia, nitrite and sulphide concentration.
