Abstract

Batu Bara Regency is located on the East Coast of North Sumatra, which borders the Malacca Strait. Gulamah fish (Johnius trachycephalus) so far is only used as salted fish with low economic value. However, recently gulamah fish have high economic value and are hunted for their swimming bubbles to be processed into food ingredients such as soup. In addition to the information obtained from collectors and fishermen, these fish bubbles are also used as material for making operating threads. Morphometric data can provide clear information about the taxonomic status of gulamah fish comprehensively. Bioactive compounds are compounds contained in the bodies of animals and plants. This study aims to obtain the relationship between morphometric results with the swimming bubbles of gulamah fish and to obtain the content of bioactive substances in the swimming bubbles of gulamah fish. The results of the regression analysis and the graph of the relationship between length and weight with the coefficient of determination are R² = 0.8736, meaning that 87.36% of fish weight gain occurs due to the increase in fish length or this shows that the correlation coefficient between the length and weight variables has a strong relationship. The results of phytochemical screening of gulamah fish swimming bubble samples have alkaloids with Bouchardart, Maeyer, Dragendroff and Wagner reagents.

Abstract

Indonesia's huge fishery potential has been recognized by the world. Fishing is an effort/activity that involves the exploitation of a resource in the sea or through public waters, whether commercially or not. The Malacca Strait is one of the territorial waters that is bounded by three countries, namely Indonesia in the west, Malaysia in the east and Thailand in the northeast. One of the catches of pelagic fisheries in the waters of the Malacca Strait that has important economic value is mackerel. This study aims to understand trends in fish catches, examine the effect of variations in temperature and chlorophyll-a in fish catches and provide basic information for fisheries management in the waters of the Malacca Strait. The stages of this research method consist of 3, namely first, chlorophyll-a and temperature data input from in-situ measurements and satellite data and catch production data, the second is the process stage, namely data input in the correlation test and t test and monthly CPUE production data. bloated and cob for 5 years. The results showed that the fluctuations in SST values in the Malacca Strait in 2020 ranged from 25.11 0C - 31.07 0C, the range of chlorophyll-a concentrations in the waters of the Malacca Strait from January 2015 to December 2020 was between 0.17 mg/m3 (February 2015). 2006) to 2.70 mg/m3 (December 2016). The variation in the catch of mackerel (Rastrelliger sp) in the waters of the Malacca Strait is in the range between 23,701.3 kg/trip (February 2007) to 105.47 kg/trip (March 2017). The number of tuna catches in the waters of the Malacca Strait is in the range of 2.94 kg/trip (December 2016) to 173.20 kg/trip (March 2016).
