Abstract

The objective of this research was to determine the decline in freshness of skipjack tuna stored at room temperature. Fish freshness testing was carried out using organoleptic tests such as eyes, gills, odor and texture of the fish, as well as counting the number of bacteria taken from the gills of skipjack tuna. Skipjack tuna was taken from 3 different markets in Mataram City. Observations on the fish were carried out twice, the first in the morning after the fish was taken from the market at 09.00 WITA and the second observation at 15.00 WITA. The results of the study showed that in the morning the skipjack tuna was in a condition of declining quality freshness, then during the day the quality of the skipjack tuna decreased further with a condition that was almost rotten. The results of observations of total bacteria also showed that in the morning the total bacteria had passed the predetermined threshold and during the day the number of bacteria increased until it could not be counted.

Abstract

This study evaluated the effects of waterborne polystyrene microplastic exposure on the growth performance of Siamese fighting fish (Betta splendens) over a 45-day rearing period. A completely randomized design with four treatments and three replicates was applied: 0, 50, 100, and 150 mg/L. The evaluated growth variables comprised absolute length gain, specific length growth rate, absolute weight gain, specific growth rate, feed conversion ratio (FCR), and survival rate (SR). Data were analyzed using one-way ANOVA followed by Tukey’s test at the 5% significance level. Polystyrene microplastic exposure significantly affected absolute length gain, specific length growth rate, absolute weight gain, and specific growth rate (p < 0.05). Fish reared without microplastic exposure consistently showed the highest growth performance, whereas the 150 mg/L treatment produced the lowest values across the principal growth endpoints. By contrast, FCR tended to increase with increasing microplastic concentration, but the effect was not statistically significant (p > 0.05). SR remained 100% in all treatments, indicating that the tested exposure levels produced sublethal rather than lethal effects under the present experimental conditions. Water quality remained within a range generally tolerated by betta fish, suggesting that the observed response was more closely associated with microplastic exposure than with overt deterioration of the rearing medium. Overall, waterborne polystyrene microplastic exposure reduced the growth performance of B. splendens and should be considered a relevant emerging stressor in ornamental fish culture.
