Abstract

The purpose of this service was to actualization the of milkfish cultivation field school activities implementation in the Pekalongan City coastal. The service method used was counseling activities with a certain thematic coupled with field practice. Then, the activity participants were given a question instrument questionnaire. The results of the analysis of this community service activity showed that the majority respondents (12 people) stated that there was an increase in knowledge related to procedures for cultivating fish after joining the program. Additionally, from participating survey their insights increased and their mastery of technology also became more proficient, and they gained new relationships. In general, this program was very beneficial for them as program recipients, with the impact of increasing their mastery of activity material by 60-99%. The level of mastery of the material was 60-99%, with 6 people responding 60-79%, 5 people responding 80-99%, and 1 person responding >60%. The conclusion of the milkfish cultivation field school activities in the coastal area of Pekalongan City was that, in terms of evaluation, it was very good. Milkfish cultivation field school activities proved to be an effective means of transferring information from researcher or academician to fish farmers in the Pekalongan area.

Abstract

Introduction: Prorocentrum sp. is one of the harmful algae genera that often grows in the aquatic ecosystems of vaname shrimp (L. vannamei) ponds. The purpose of this study was to determine the abundance and dynamics of the Prorocentrum sp. during the shrimp culture period of vaname shrimp (L. vannamei) in intensive ponds. Method: This research was conducted on 4 ponds with a size of 3,200 m2 and a stocking density of 120 fish/m2. The research variables observed were water quality parameters and Prorocentrum sp. which is carried out every 7 days during the shrimp cultivation periods. Result: Based on the results of study, the water quality parameters during the shrimp culture period tend to be stable, except for the water pH parameters which have relatively high afternoon pH fluctuations. Prorocentrum sp. genera during the shrimp culture period, the plankton genus was the most dominant compared to other genera of the Dinoflagellate class. The dynamics of the Prorocentrum sp. abundance on the intensive pond, there was a significant correlation between the solubility of TAN (Total Ammonia Nitrogen) content of 74.8% and the water temperature of 83.3%. Conclusion: The abundance dynamics of Prorocentrum sp. genera during aquaculture period of vaname shrimp (L. vannamei) fluctuated dynamically following the solubility trend of TAN (Total Ammonia Nitrogen) levels and water temperature flux in the pond ecosystem
