Fishers, including trammel net fishers, have different respond due to seasonal changes. The research aims to calculate shrimp season index, to identify the impact of seasonal changes related to income of trammel net fishers, and to identify the adaptation pattern of trammel net fishers related to shrimp season changes. The data collected were trammel net fishing unit performance, trammel net fisherman adaptation methods, investment data, income, and fishermen's capital as well as trip data and trammel net shrimp production data for five years (2012-2016). Data analysis used fishing season index, fishing season impact related to income of fishers, and fishers adaptation to seasonal changes. The results showed that there are five months were identified as peak season of shrimp i.e. June, September, October, November, and December. Other results showed that seasonal changes have impacted to trammel net fishers income amounted Rp 6.185.800/vessel/trip. At the peak season fishing, fisher income were Rp 6.591.495/vssel/trip, however at the low season fishers income were Rp 405.695/vessel/trip. In addition there were five adaptation pattern related to seasonal changes of trammel net fishers which were 37% lending money and selling stuffs, 33% repairing fishing gear, 13% fishing gear diversification, 10% changing the fishing ground, and 7% income diversification. In conclution that fishers who choose adaptation pattern of fishing gear diversification have the highest income compared to fishers who choose other types of adaptation.

Handlines are a fishing gear that is commonly used by fishermen in Banten Bay. However, the catches obtained by fishermen are few. This is because of the lack of information about the potential fishing ground that fishermen have. One of the methods to increase the effectiveness and efficiency of fishing operation is the information about the availability of fishing ground. The used of portable FADs (Fish Aggregating Devices) technology is expected to create a fishing ground so that fishing operation become more effective and efficient. The research purpose is to compare the productivity and composition of handline catching by using and without portable FAD and to determine the effectiveness of portable FAD. The method used was an experimental fishing method with 20 trips. Research showed that the dominant catches of handline fishing with portable FADs were goatfish, bream, black grouper, mackerel. Goatfish, bream, and black grouper were dominated by large sizes. The total catch of handline was 931 fish. The composition of the catch with the portable FAD was 504 of fish, while without the portable FAD was 427 of fish. The productivity of handline with portable FAD was 1.29 kg/trip, while the productivity of handline without FAD was 0.99 kg/trip. Portable FAD use during fishing operations was more effective compare to fishing operations without portable FADs.

ABSTRACTRumpon or Fish Aggregating Devices (FADs) had been used by purse seine and handline fishermen in Pacitan Regency since 2005. The use of rumpon has been associated with the catching of immature fishes in large number that would disrupt the sustainability of fish resources.Â The aims of this study were to measure fishing productivity of purse seine and handline fleets operated around FADs deployed in eastern Indian Ocean waters and analyze the size distribution and gonad maturity index of the catch. This study was conducted at Tamperan Fishing Port of the Pacitan Regency, East Java Province. Daily fish landing data from both fishing fleets were collected from the Tamperan auction hall from January to December 2014 for productivity calculation. About 289 fish samples from 6 dominant species was taken randomly on-board of 3 purse seine and 2 handlines vessels from 8 different FADs for size distribution and gonad analysis. The average productivity of purse seine fleets in 2014were 6,7 tonnes/trip (s = 5 tonnes/trip) while handling fleets average productivity were 0,9 tons/trip (s = 0,6 tons/trip. Purse seine catch were dominated by immature and juvenile fish while handlines catch were larger and already mature fishes.Keywords: FADs, fishing productivity, gonad analysisABSTRAKRumpon atau Fish Aggregating Devices (FADs) telah digunakan oleh nelayan pukat cincin dan pancing ulur di Kabupaten Pacitan sejak tahun 2005.
