Abstract

Catfish is one type of carnivorous fish that can adapt to artificial feed formulations. attractants from animal sources such as earthworm meal can be used as attractants in feed. Attractants added to feed in small amounts can stimulate appetite and fish growth. This study aims to determine the best dose of earthworm meal addition as an attractant in feed so that it affects the growth of catfish. This study used experimental method of Completely Randomised Design (RAL) with 5 treatments and 3 replicates. The treatment used was the addition of earthworm meal attractant in catfish feed at a dose of 0% (A), 5% (B), 7,5% (C), 10% (D), and 12,5% (E). The results showed that the addition of 10% earthworm meal attractant in feed (Treatment D) was the best dose for catfish growth which was able to increase absolute length growth by 6,85 cm and specific growth rate (SGR) by 4,74%/day.

Abstract

One method to extend the shelf life of fish filets is through antibacterial preservation, which can be achieved using a cassava peel fermentation solution containing lactic acid bacteria that can combat spoilage bacteria in fish. This study aims to determine the effect of cassava peel fermentation solution on the organoleptic quality of red tilapia filets during low-temperature storage (5°-10°C). Red tilapia filets were soaked in a cassava peel fermentation solution with varying salt concentrations across four treatments: 0% (control), 2%, 3%, and 4%, with a soaking time of 30 minutes per filet according to the treatment. Observations were conducted on days 1, 4, 7, 8, 9, 10, 11, and 12, with organoleptic evaluations (appearance, aroma, slime, and texture) and data analysis using the Friedman statistical test, Multiple Comparison, and Bayes test. Results indicated that a 3% salt concentration yielded the best organoleptic value, especially on day 10, with aroma as the highest-ranked parameter according to the Bayes test (weight 0,44), followed by appearance (0,37), slime (0,10), and texture (0,08). Thus, cassava peel fermentation solution with a 3% salt concentration effectively extends the shelf life of red tilapia filets.
