This study aims to study the characteristics of acoustic backscattering of parrot fish and their relationship to fish length measurements. The benefits of this study are useful for estimating the size and abundance distribution of parrot fish in a waters. Acoustic backscattering measurements were carried out ex-situ using the tethered method, where the parrot fish was hung at a depth of 2 meters below the transducer and sounded with a Simrad EK-15 echosounder at a frequency of 200 kHz. Recording data were analyzed with Echoview 8 software to obtain target strength (TS) data. The results showed that the backscatter of parrot fish (C. sordidus) had an average TS value of -49.42 dB at standard lengths ranging from 14 to 22 cm. Differences in TS values in parrot fish are thought to be influenced by body length, swimbladder length and swimming activity. The ratio of the size of the swimbladder length and body length does not indicate an association with TS values. The relationship between TS and standard length of parrot fish (C. sordidus) was formulated in the equation TS = 10.43 Log SL - 62.65 (R2 = 0.752). This result is different from the Love (1977) provision where the acoustic backscatter of a fish is the square of the length of the fish set with a slope (b) of 20.","PeriodicalId":193095,"journal":{"name":"SAINTEK PERIKANAN : Indonesian Journal of Fisheries Science and Technology","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122128142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study is determining the effect of several salinity concentrations on zooxanthellae density and their relationship to photosynthesis (NPP), respiration and primary productivity (GPP). This research used experimental method was conducted on November 13 – February 7, 2020 at Coastal Development Laboratory (LPWP). Corals used as research objects are Acropora sp. taken from the waters of Pulau Panjang, Jepara. Acropora sp. is given salinity concentration treatment (25 /oo, 30 /oo, 35 /oo). Observations were made at 0, 3, 6 and 9 day time intervals. The results showed that the difference in salinity concentration significantly affected the density of zooxanthellae.

Fishery resources are a new potential in the regional economic development of Aceh province. Fish resources that have great potential are from the large pelagic fish groups, including Tuna, Small Tuna and Skipjack (TTS) . Fishery characteristics are used to carry out sustainable fishing. This research was conducted at PPS Kuta Raja, Aceh for one year. Data collection was carried out directly through site surveys and interviews with related fisheries actors. Biological data and capturing aspects were carried out using a stratifield random sampling system by placing enumerators. The results showed that the production of TCT at PPS Kutaraja was dominated by 2 fishing gears, purse seine and hand lines. Based on the results of enumeration in 2020, the estimated total production of tuna skipjack and small tuna at PPS Kuta Raja reaches 11,520 tons. The highest total estimated fish catch is skipjack tuna (Katsuwonus pelamis) (SKJ) 5,802 tons, Bullet tuna (Auxis rochei)(BLT) 2814 tons, Yellow fin  (Thunnus albacares) (YFT) 2,452 tons, Krai Tongkol (Auxis thazard) (FRI) 448 tons, and Eastern little tuna (Euthynnus affinis) (KAW) 1,745 tonnes. All of the fish caught were dominated by immature fish. So it is very necessary to evaluate the use of fishing gear or the licensing of FADs.

The objective of this study was to determine the phytochemical screening, total phenolic content, and antioxidant activity of P. pavonica Hauck extract. The phytochemical screening and determination of total phenolic compounds were carried out using two different solvants with ethanol and ethyl acetate. Whereas antioxidant activity was evaluated using the DPPH (1,1-diphenyl-2-picrylhydrazyl) free radical scavenger method with UV-vis spectrophotometer. The qualitative analysis of phytocemical constituents revealed the presence of alkaloids, steroids, flavonoids, phenols, and saponins. Furthermore, for total phenolic compounds, the ethanolic extract had a higher content (20.34 mgGAE/g) dry sample than ethyl acetate extract (7 mgGAE/g).

Tujuan penelitian ini adalah untuk mendeskripsikan proses transportasi glass eel, moda transportasinya, dan parameter kualitas air pada saat ditransportasikan dari nelayan sampai ke kolam pembesaran serta mengidentifikasi risiko dan menentukan mitigasi transportasi glass eel. Metode dalam penelitian ini adalah observasi dan wawancara kepada nelayan dan pengumpul mengenai aktifitasnya dan parameter kualitas air yang digunakan. Analisis yang digunakan berupa analisis deskriptif, analisis komparatif, dan analisis risiko dan mitigasi menggunakan metode HIRAC. Hasil penelitian menunjukan bahwa proses transportasi glass eel berawal dari nelayan ke pengumpul. Pengumpul mengumpulkan hasil tangkapan untuk selanjutnya ditransportasikan ke kolam pembesaran.
