Debby Dyanessa Saragih — 2024-03-08

Tubifex worms are a vital natural food supply for the growth and maturation of fish larvae and fry in freshwater fish hatcheries. Tubifex worms are typically housed in a substrate that contains abundant silt, minimal water flow, and a high concentration of organic matter. When there is a substantial amount of organic matter, tubifex frequently serves as the primary host for numerous bacteria and parasites. The study was conducted at the Health and Environmental Laboratory of the Tatelu Freshwater Fisheries Center in North Sulawesi during the months of April and May 2022. The study aimed to identify the bacterial and parasitic organisms present in Tubifex worms and the culture medium used for their maintenance. Eight rearing tank was randomly sampled, with 16 samples collected, consisting of Tubifex worms and media water. Subsequently, the parasites and A. hydrophila bacteria were identified. Several tests were used to look for parasites and bacteria in the samples. These included urea, motility, indole, citrate, oxidase, catalase, triple sugar iron agar (TSIA), oxidase, and catalase. The results indicated the absence of parasites in all samples. However, bacteria were detected in the samples of Air Media (B1), Tubifex (B2), Air Media (B2), Tubifex (B3), Air Media (B3), Tubifex (B4), Air Media (B4), Tubifex (B5), Air Media (B5), Tubifex (B6), Air Media (B6), Tubifex (B7), Air Media (B7), and Tubifex (B8).

Immanuel Perdinan Panggabean — 2024-03-08

Freshwater lobster (Cherax quadricarinatus) is a freshwater fishery commodity that is very promising as a substitute for seawater lobster. The egg hatching process is one of the factors that really determines the success of freshwater lobster cultivation activities. The aim of this research was to evaluate the percentage of eggs hatching degree and survival of freshwater lobster seeds hatched using the incubation method. This research used a completely randomized design method with 4 treatments and 3 replications. Treatment A as control (natural hatching of lobster eggs), Treatment B (incubation phase 2 or 4-6 days after fertilization), Treatment C (incubation phase 4 or 10-12 days after fertilization), Treatment D (incubation phase 6 or 16-18 days after fertilization). The test eggs used in this study were obtained from the same parent. Meanwhile, natural hatching uses eggs from different parents. The results showed that the degree of hatchability of naturally hatched and incubated lobster eggs was significantly different (p<0.05). In incubation hatching, the best egg hatching rate was in phase 4, namely 91.1 ± 3.85a with a seed survival rate of 91.66 ± 14.43a. Thus, hatching of freshwater lobster eggs at various stages of embryonic development with an optimum temperature of 30°C should be carried out in phase 4 or 10-12 days after fertilization with an egg hatching time of 33 days.

Gastropods are molluscs (soft-bodied) animals that have shells and move with their stomachs. Gastropods can be associated with seagrass ecosystems, because they provide food, spawning, breeding and shelter from predators. Seagrass conditions can influence the level of abundance and types of gastropods in the water. This study aims to determine the association of gastropods with seagrass density. The method used in the research is the purposive sampling method, using a 1 x 1 m quadrant transect. The results of the research were that the gastropods found on the Coast of Labuhan, Sepulu, Bangkalan were the Clypeomorus bifasciata type with the highest abundance of 301.5 ind/m2, while the lowest abundance of gastropods were Coralliophila caribaea, Cypraea dillwyni, Nerita planospira with a value of 0.5 ind/m2. The diversity index (H') value in the "medium" category is around 1.115-1.35, the uniformity index (E) is "low" around 0.25-0.28 and the dominance index (C) is "medium" around 0.39- 0.44. One type of seagrass was found, namely Thalassia hemprichii, with a density of between 50-61 ind/m2 in "rare" conditions. The association of gastropods with seagrass density obtained a Pearson Product Moment correlation value of 0.684, including the criteria for a strong relationship, with the calculated r value being higher than the r table (0.684 > 0.666). This is confirmed by the t test where the calculated t is higher than the t table (2.480 > t table 2.365), thus proving that there is a strong and unidirectional association between gastropods and seagrass density, meaning that the higher the seagrass density, the stronger it is to support a high gastropod density.
