Toxicity is the ability of a substance or chemical which, when exposed for a certain period, can cause damage to organisms. Factors that influence toxicity are composition, type, duration and frequency of exposure, recipient biota species and environmental characteristics. The results of this test describe the values LC₅₀-96 hours or LC₅₀-48 hours. The LC₅₀value is the concentration at which the extract solution can cause population death of up to 50%. This study aims to determine the concentration of acute toxicity of liquid palm oil waste on tilapia fish seeds and its effect on the organoleptic properties of tilapia. This research was carried out from May to July 2023 at the Aquatic Resources Management Laboratory, Faculty of Agriculture, Tanjungpura University. The method used is a static method in acute toxicity tests to determine the death of 50% of the number of test organisms. This research was carried out in 4 stages, namely preparation, preliminary test, toxicity test and treatment test. The toxicity test data was then analyzed using probit analysis. The LC₅₀-96 hours value of palm oil liquid waste for the tilapia fish seed biota test is 4.88 mg/l. The LC₅₀-96 hours value obtained from probit analysis is used to determine the TUa (Toxicity Unit Area) value by converting the LC₅₀-96 hours value. The TUa value obtained was 20,49 indicating that the acute toxicity level of liquid palm oil waste causes acute toxicity.

Several factors influence the number and type of fish caught in a trap,
including the size of the trap, fish activity, mobility, design, bait, soaking time,
provision of shelter, moon phase, visibility of the trap in the water material, and
type of funnel. It is important to identify problems related to trap placement so that
the productivity of fish resources can be optimal. This research aims to analyze the
composition of fish species caught, length at first capture, and differences in catch
rate of bottom traps based on different fishing locations. The research was carried
out from April to October 2023 in Talaga Nipa Hamlet, Waisala District, and West
Seram Regency using experimental fishing methods. The results of the research
showed that there were 20 species of fish caught in the waters of Sanahuni Hamlet
(Location A), with the most dominant type of fish being Pterocaesio tile, namely
31.40%. Meanwhile, in the waters of Haya Pulo Hamlet (Location B), 16 species of
fish were caught, with the most dominant species being Scarus rubroviolaceus at
22.86%. On average, caught fish such as Caesio cunning, Scarus rubroviolaceus and
Caesio caerulaurea are caught before they reach maturity. The bottom trap catch
rate in the waters of Sanahuni Hamlet (Location A) is higher than in the waters of
Haya Pulo Hamlet (Location B). Differences in the number and types of fish caught
in traps can be influenced by various factors, such as fish migration, food
abundance, oceanographic conditions, trap design and construction, depth of
operation of fishing gear, and damage to coral reefs due to destructive bomb fishing.

Analisis Kandungan Logam Berat pada Minyak Ikan Sardine (Sardinella sp.) Hasil Penepungan dari Bali

2024-05-10T00:49:11+00:00

Sardines, or lemuru, are a group of pelagic fish that are often found in the
waters of the Bali Strait because they have potential economic and strategic value
such as a source of income for fishermen, a provider of raw materials for the
processing industry, and a source of local income. Sardine, or lemuru fish, is a
pelagic fish that has a high oil content and can be used in the processing industry.
In processing industries such as the flour industry, waste will be produced, one of
which is liquid waste such as fish oil. Fish oil, which is a by-product, can be utilized
further, but the impurity components, one of which is the heavy metal content in the
oil, must be removed first. The way to remove or reduce the concentration of heavy
metals in fish oil is through a series of purification techniques. The aim of this study
was to determine the heavy metal content in sardine or lemuru fish oil from Bali,
which has been purified first, and then compare the results of these heavy metal
tests with the results of other studies. The purification carried out was divided into
3 stages, namely degumming using water (without citric acid), neutralization using
NaOH, and bleaching using magnesol XL 5% (w/v). Crude fish oil (unrefined) and
pure fish oil are then tested for heavy metals. The results show that purifying fish
oil can reduce heavy metal content. These results are also in line with research
conducted by several previous researchers. So it can be concluded that the refining
stage can reduce the heavy metal content so that it meets the International Fish Oil
Standard (IFOS).

Freshwater lobster (Cherax quadricarinatus) is a type of lobster that has the potential for developed as a cultured organism. The problem that often occurs is the low number of freshwater lobster production due to the relatively long reproductive time. Vitamin E is a nutrient that plays a role in improving the spawning process in animals. This research aims to determine the effect of vitamin E to artificial feed at different doses on spawning. The test animals used were 16 female freshwater lobsters measuring 4 inches, aged 6 months, with an average weight of 30-55 grams. The research was conducted over 60 days using an experimental method with a completely randomized design (CRD) consisting of 4 treatments with 4 replications each. Treatment A was without vitamin E, Treatment B had 250 mg/kg of feed, Treatment C had 450 mg/kg of feed, and Treatment D had 650 mg/kg of feed The results showed that the levels of gonad maturity, fecundity, degree of fertilization, egg hatchability, and survival rate were not significantly different among treatments. However, Treatment C yielded the best results, with a gonad maturity level of 10.60%, fecundity of 281.53 eggs, a fertilization rate of 8.59%, a hatchability rate of 62.50%, and a survival rate of 100%. Data analysis was conducted using analysis of variance (ANOVA) at a 95% confidence level. The results indicate that the addition of vitamin E to feed at different doses does not significantly affect the spawning of freshwater lobsters.

Sebaran Parameter Akustik Ikan Pelagis Kecil di Teluk Cenderawasih, Papua

2024-04-30T02:22:38+00:00

Cenderawasih Bay is one of the territorial waters of Indonesia which has a fairly high fishery potential. In 2022, the bay's fishery potential reaches 135,140 tons but the utilization rate is still at 0.3, which means that it has not been fully utilized, especially small pelagic fish. This shows the need for an estimation of the distribution of fish in the bay that can take advantage of the hydroacoustic method. This research uses a split beam echosounder SIMRAD EY-60 which is operated at a frequency of 38 KHz and a pulse duration of 1,024 ms to obtain fish distribution data. Environmental parameter data was obtained using data from marine.copernicous.eu at the same time as fish distribution data collection. The distribution of fish also shows a fairly diverse distribution of values with the highest SV value range at -59.7 to -57.4 dB and the highest TS range at -59.4 to -46.7 dB. The distribution of fish was also seen to be more concentrated in areas with warm temperatures and spread evenly in each salinity range with the number of fish detected approaching areas of higher chlorophyll concentration.
