Judul: Dampak Ekologis dan Ekonomis Kegiatan Perikanan Tangkap di Palabuhanratu, Sukabumi, Jawa Barat.
Abstrak: To study the sustainable fishing management, an integrated analysis of ecology economy should be sistematicaly conducted. The objective of this study are: (1) to determine the ecological and economic impact of fishing activities on community structure and trophic level of catch; 2) to determine optimum utilization fish stock based on bio-economic aspects. The results showed that the catches landed in PPN Palabuhanratu were dominated by highest food web level (trophic level) of carnivore group fish (TL5). The annual catch of this TL group was increase, the potentially threaten its prey of TL 2 to TL 4. The most dominant catch in study location was hairtail (Trichiurus savala). Hairtail was dominanly caught by hand line and payang (seine nets). The catch of this spesies was larger than the size of the allowable size based on length at first maturity parameter. Length-weight relationships of this species seemed negative allometric growth pattern (b = 2,6734). The sustainable utilization of the hairtail fish stock in the fishing ground of Palabuhanratu is 222.248 kg with annual effort of 14.571 trips for handline fishing fleet and 6.267 trips for payang fishing fleet. Bio-economic optimization of payang fishing fleet was higher than hand line fishing fleet.

Judul: Kajian Bioekonomi Perikanan Rawai Tuna di PPN Palabuhanratu, Sukabumi, Jawa Barat
Abstrak: High demand and production of tuna fish in PPN Palabuhanratu has caused exploitation of tuna increased and potentially affect the biological condition and sustainability of fishing business. This study aimed to know biological condition, utilization status, and optimum management of tuna fish resources. Diversity index of shannon-wiener (H’), length at first maturity, length-weight relationships, and bioeconomy model was used in this study for data analyses. Result of this study show that the H’ value was 1.60-2.42. Based on the length at first maturity parameter, 3.84 - 41.02 % for bigeye tuna, 0.72% for yellowfin tuna, and 65.63% for swordfish was lower than unallowable catch size. The length-weight relationships of bigeye and yellowfin tuna were indicated negative allometric growth model, whereas swordfish positive allometry. Actual effort of tuna fishery in PPN Palabuhanratu was not indicated a biological overfishing condition, however it indicated an economical overfishing condition. Bioeconomy optimalization was achieved at fishing effort of 597 trips, production of 2481.14 tons, and economic rent of Rp 67.704.000.000,-.

Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
