The purpose of this study was to determine the selectivity and level of environmental friendliness of mini bottom trawl in Pangandaran District. This research conducted on May-October 2017. Primary data obtained from purposive sampling either by interview or observation Selectivity indicator used was selectivity of catch species and size. Environmental friendly fishing was evaluated based on the FAO criteria. The result showed that catch rate of mini bottom trawl was 26.45 kg/hour. The main catch of mini bottom trawl in Pangandaran District was Trachypenaeus asper amount of 39,5% while by catch was Acetes sp¸ Oiolithes ruber, Trichiurus lepturus, and others catch with amount 60,40%. Catch size of mini bottom trawl main catch was ranged 4 cm - 9.90 cm. The main catch was 39,00% was more than size capture and under size capture was 61.00%. Catch utilization of this fishing gear was 93%. The result evaluation of environmental friendliness based on catch selectivity was 6 point which mean ‘less environmentally’ friendly while FAO criteria showed 18 point which mean ‘not environmentally’ friendly fishing.

Purse seine merupakan alat tangkap yang banyak digunakan oleh nelayan di Kabupaten Indramayu. Purse seine memiliki hasil tangkapan yang multi species sehingga memiliki tingkat selektivitas yang rendah. Hal ini dapat menjadi salah satu indikasi sumber daya perikanan tangkap di Pantai Utara Jawa berpotensi mengalami overfishing. Riset ini bertujuan untuk menganalisis tingkat selektivitas alat tangkap purse seine waring berdasarkan frekuensi ukuran panjang ikan, proporsi hasil tangkapan, indeks keanekaragaman, dan indeks dominansi alat tangkap purse seine waring di Pelabuhan Perikanan Pantai (PPP) Dadap Kabupaten Indramayu. Pelaksanaan riset dilakukan di PPP Dadap pada Bulan September – Oktober 2022. Metode riset yang digunakan yaitu metode survey dengan analisis deskriptif kuantitatif. Hasil riset menunjukkan bahwa hasil tangkapan utama adalah jenis ikan teri (Stolephorus sp.) dengan total bobot sebesar 30.415 kg. Sedangkan hasil tangkapan sampingan didominasi oleh ikan tembang (Sardinella fimbriata) dengan total bobot sebesar 74.296 kg. Distribusi ukuran Panjang ikan teri berada pada kisaran panjang 2,7 – 8,5 cm dengan proporsi ikan teri layak tangkap sebesar 66,58%. Hasil tangkapan utama berdasarkan bobot memiliki proporsi sebesar 23,32% dan sampingan 76,68%. Nilai indeks keanekaragaman spesies (H') sebesar 0,85 dan nilai indeks dominansi (C) sebesar 0,49. Alat tangkap purse seine waring memiliki sifat selektif positif terhadap ukuran, namun negatif terhadap spesies. Sedangkan berdasarkan indeks keanekaragaman dan indeks dominansi, alat tangkap purse seine waring memiliki nilai selektivitas yang rendah.

Devil rays (Mobula spp.) are caught in fisheries across the Indian Ocean, with reports of significant recent declines in catch and sightings. Globally, the few populations studied have extremely low population growth rates due to low fecundity and long reproductive cycles, making them highly vulnerable to overfishing. To allow for assessment of the current sustainability of devil ray catch in the Indian Ocean, we provide estimates of age using the caudal vertebrae; somatic growth using a Bayesian, multi-model approach; maximum intrinsic rate of population increase (r _max ); and fishing mortality for Endangered Spinetail Devil Ray (Mobula mobular) and Bentfin Devil Ray (M. thurstoni) sampled from small-scale fisheries catch in Indonesia, Kenya, and Pakistan. The oldest individuals of Spinetail Devil Ray (n = 79) and Bentfin Devil Ray (n = 59) were 17.5 and six years, respectively. Both species had relatively low growth coefficients (k = 0.05 and g = 0.19 year⁻¹, respectively), with the von Bertalanffy and logistic models providing the best fitting growth models, and low r _max (0.109 and 0.107 year⁻¹, respectively) indicating that they are highly sensitive to overexploitation. Fishing mortality F estimates (0.16 and 0.18 year⁻¹, respectively) were higher than r _max and exploitation ratio E (0.77 and 0.80, respectively) were higher than an optimum value of 0.5 for biological sustainability for both species, suggesting that the fisheries catches of the species are unsustainable. We demonstrate an approach to assess data-poor species and apply this to two Indian Ocean devil ray species. The results highlight the urgent need for better management actions to reduce the catch of all devil rays to prevent species extinction and aid in population recovery.

Symbiodiniaceae species is a dinoflagellate that plays a crucial role in maintaining the symbiotic mutualism of reef-building corals in the ocean. Reef-building corals, as hosts, provide the nutrition and habitat to endosymbiotic Symbiodiniaceae species and Symbiodiniaceae species transfer the fixed carbon to the corals for growth. Environmental stress is one of the factors impacting the physiology and metabolism of the corals-dinoflagellate association. The environmental stress triggers the metabolic changes in Symbiodiniaceae species resulting in an increase in the production of survival organelles related to storage components such as lipid droplets (LD). LDs are found as unique organelles, mainly composed of triacylglycerols surrounded by phospholipids embedded with some proteins. To date, it has been reported that investigation of lipid droplets significantly present in animals and plants led to the understanding that lipid droplets play a key role in lipid storage and transport. The major challenge of investigating endosymbiotic Symbiodiniaceae species lies in overcoming the strategies in isolating lesser lipid droplets present in its intercellular cells. Here, we review the most recent highlights of LD research in endosymbiotic Symbiodiniaceae species particularly focusing on LD biogenesis, mechanism, and major lipid droplet proteins. Moreover, to comprehend potential novel ways of energy storage in the symbiotic interaction between endosymbiotic Symbiodiniaceae species and its host, we also emphasize recent emerging environmental factors such as temperature, ocean acidification, and nutrient impacting the accumulation of lipid droplets in endosymbiotic Symbiodiniaceae species.

Ikan layur (Trichiurus lepturus) merupakan komoditas utama yang bernilai ekonomis tinggi di Pangandaran. Penelitian ini bertujuan menentukan perbandingan selektivitas alat tangkap gillnet dengan hasil tangkapan ikan layur berdasarkan frekuensi panjang, proporsi hasil tangkapan utama dan sampingan, serta kurva selektivitas di Kabupaten Pangandaran. Data yang digunakan dalam penelitian ini adalah data primer dan sekunder. Data primer merupakan data hasil tangkapan dan panjang ukuran ikan. Data sekunder yang dikumpulkan adalah data produksi perikanan tangkap di Kabupaten Pangandaran. Analisis data dilakukan dengan bantuan software Microsoft Excel. Ikan layur di Kabupaten Pangandaran ditangkap menggunakan alat tangkap gillnet dan pukat pantai, walaupun didominasi oleh gillnet. Hasil penelitian menunjukkan gillnet berukuran mata jaring 3 inci dengan nilai L75 = 73,2 cm dan S3l = 0,64 lebih selektif dibanding gillnet ukuran mata jaring 2 inci dengan nilai L75 = 69,2 cm dan S2l = 0,62. Alat tangkap gillnet ukuran mata jaring 3 inci lebih selektif menangkap ikan layur yang sudah layak tangkap di Kabupaten Pangandaran dibandingkan dengan gillnet ukuran mata jaring 2 inci.
