Abstract

The vast seagrass field allows the number of biota that live associated with seagrass. One of the wealth of marine resources that is often found is mollusks such as snails, shellfish, octopus, cuttlefish and squid. Mollusks are found in coastal areas with seagrass beds as their habitat. One of the most commonly found mollusk groups in Bere Bere village waters is gastropod and bivalvia. Research Objectives To determine the distribution of mollusks in the waters of Bere-Bere Village. This study was conducted in October 2021 to January 2022 located in the waters of Bere-Bere Village, North Morotai District, Morotai Island Regency. Data collection uses the quadratic transect method to identify mollusks (gastropods and bivalvia) that are found in each square. The transect rope is pulled perpendicular to the sea along 50 m during the receding sea water starting from the zero point (0), to the point of 50 m, the square distance is 10 m while the transect distance is 25 m, while the distance between the station is 50 m, then the square is placed on Every distance of 10 m along the transect that can represent the locations that have gastropod and bivalvia samples. Organism found along the transect, in the squares observed and then identified using an identification book. Field work practices were found 11 types of gastropods (Conus Gladiator, Conus Littyus, Trochidae sp, Cerithiidae sp, Canarium sp, Muricodrupa fenestrata, Vexillum sp, Strombus Campbelli, Strombus Campbell , Conus Episcopatus, Conus Sulcatus, Conus Pennaceus) and 3 types of Bivalvia (Lambis Lambis, Pinna Muricata, Diloma Radula) which are spread on three stations in the waters of Bere-Bere Village.

Abstract

Excessive utilization (over-exploited) will have an impact on reducing the productivity of resources including jackfruit seed fish (Upeneus vittatus). This impact causes changes in abundance, productivity and community structure, such as changes in species dominance, size spectra and catch, which results in depletion of stocks and ends in the extinction of this fish population. So far there is no data and information regarding the biological aspects of the morphology of the use of jackfruit seed fish (Upeneus vittatuss) in Morotai Island Regency. The aim of this research is to analyze the relationship between length and weight of jackfruit fish (Upeneus vittatus) caught in the waters of Imam Lastori Harbor, Morotai Island Regency. Data collection was carried out directly in the field (in situ) by measuring the body length and weight of jackfruit seed fish (Upeneus vittatus). The data obtained were analyzed using simple linear regression analysis. The results of a simple linear regression analysis between the total length and weight of the jackfruit fish (Upeneus vittatus) caught in the waters of Imam Lastori harbor obtained the equation: W (weight) = 1.30 x L (length) = 1.35 indicating that for every 1 increase .30 gram units of the weight of jackfruit seeds will increase 1.35 cm units of the length of kuniran jackfruit seeds (Upeneus vittatus). The b value (exponent) of 1.35 indicates a negative allometric growth pattern. This is in accordance with the criteria for the length-weight relationship if the b value <3, then the growth form is negative allometric). Meanwhile, the determination value (R2) obtained was 0.63, meaning that 63% of the increase in fish length was due to the increase in weight (weight) of jackfruit fish (Upeneus vittatus) while 37% was caused by other factors.
