Abstract

The purpose of this study was to analyze the effect of adding commercial feed with various concentrations of the hormone thyroxine (T4) on the growth profile of star pomfret (T. Blochii, Lacapede).  This research was conducted for 50 days at BPBL Sekotong.  The method used is an experimental method with a completely randomized design (CRD) which includes 4 treatment levels and 3 replications.  consisting of: P1: control (without thyroxine hormone), P2: thyroxine hormone 1 mg/kg feed, P3: thyroxine hormone 1.5 mg/kg feed, P4: thyroxine hormone 2 mg/kg feed.  Parameters measured were absolute weight, absolute length, specific growth rate (SGR), feed efficiency (EP), feed conversion ratio (FCR), survival (SR) and water quality.  Data were analyzed using variance (ANNOVA) and continued with Duncan's test.  The addition of the concentration of thyroxone hormone (T4) in commercial feed can affect the growth of star pomfret but does not affect the value of feed utilization efficiency (EPP), feed conversion (FCR) and survival (SR).  The addition of the concentration of thyroxine hormone (T4) 2 mg/kg in commercial feed is the best treatment in star pomfret culture, because it can provide an absolute weight of 7.69 g, an absolute length of 3.50 cm, and a specific growth rate of 2.28%/day.

Abstract

Illegal fishing in Indonesian territorial waters, especially by foreign fishermen, has harmed the Indonesian state financially, because it has contributed greatly in reducing productivity and catches very significantly. It has has also threatened the sustainability of the utilization of Indonesia’s marine fishery resources. Economic losses due to IUUF are not only in the form of state income which reaches the range of Rp. 30 trillion per year, but also the loss of opportunities to utilize fish resources of around 1 million tons of fish each year that can be caught (harvested) by Indonesian fishermen, and what happens is in fact stolen by foreign fishermen. entering Indonesian waters. Foreign fishermen who often enter Indonesian waters, among others, come from Thailand, Vietnam, the Philippines, and Malaysia. To prevent and overcome IUUF activities, one of the steps taken by the Ministry of Maritime Affairs and Fisheries (KKP) of the Republic of Indonesia through the Directorate General of Supervision of Marine and Fishery Resources (DITJEN PSDKP) is to supervise fisheries such as fishing activities in the fisheries management area of ​​the Republic of Indonesia. Supervisory implementation is carried out by the Technical Implementation Unit (UPT) PSDKP. UPT Directorate General of PSDKP in handling its duties is supported by the Marine and Fishery Resources Supervision Unit (PSDKP Satker) and Marine and Fishery Resources Monitoring Post (PSDKP Post) spread throughout Indonesia. In carrying out its duties, the Fisheries Supervisory Vessel may stop, inspect, carry, and detain ships suspected of violating the law to the nearest port for further processing. In addition, based on Law No. 31 of 2004 concerning Fisheries, as amended by Law No. 45 of 2009, in certain cases Fishery Supervisory Vessels, in this case, fishery supervisors or Fisheries Civil Servants Investigators, can also take special actions in the form of drowning. The high level of fishing activity in the Indonesian State Fisheries Management Area 711 must be accompanied by adequate monitoring activities to ensure compliance by business actors, both industrial scale and small fishermen, so that the sustainability of fisheries resources can be maintained.

Abstract

Regional development with a Minapolitan concept is part of the marine and fisheries industrialization policy strategy which aims to realize accelerated increases in the income of cultivators, fishermen, processors, and marketers by integrating upstream and downstream production systems to increase the scale and quality of production, productivity, competitiveness and added value for sustainable marine and fisheries resources. The Minapolitan program is designed to increase the competitiveness of fisheries commodities which is then targeted to increase regional competitiveness and reduce the gap between urban and rural areas. This activity is intended to formulate a development center for the Minapolitan area of ​​Wajo District which will become the basis for preparing technical work plans for related agencies. Based on field results, it was found that the marine and fisheries resource potential of Wajo District was mapped into two resource potential zones, namely (1) the coastal subdistrict area (Bola, Takkalalla, Sajoanging, Penrang, Keera and Pitumpanua subdistricts) which is directly connected to the waters of Bone Gulf for the utilization of potential resources of capture fisheries and aquaculture (marine cultivation and pond cultivation); and inland fisheries areas, especially in the Tempe lake area (Sabangparu, Tempe, Tanasitolo and Belawa subdistricts). Utilization of the potential of the coastal areas of the District of Wajo, with its characteristics of an open water area directly bordering Gulf of Bone, has more potential for the development of capture fisheries, marine aquaculture, and brackish/pond cultivation with the superior commodities of seaweed and mangrove crabs as well as coastal ecotourism. Meanwhile, the Tempe Lake area is more geared towards fishing, cultivating freshwater fish and limited area management for ecotourism activities.

Abstract

The escalating demand for chicken meat over the years has led to a corresponding increase in waste generation, particularly chicken feathers. While efforts such as making dusters and cocks have been undertaken to address this issue, they have yielded limited success in effectively managing chicken feather waste. Given the significant levels of nutrients, including protein and amino acids, present in this waste, it holds immense potential as a raw material for fish feed. However, the utilization of chicken feather waste remains relatively uncommon due to the challenging digestibility of its large crude protein structure, primarily composed of keratin protein. Thus, preprocessing is essential to degrade the keratin within chicken feathers, rendering it digestible for fish. This review aims to provide an overview of the potential utilization of chicken feather meal in aquaculture, particularly in fish feed formulations, by exploring its nutritional value and various processing methods to enhance the quality of this raw material.

Abstract

Silvofishery is a cultivation activity in mangrove or mangrove areas, the type of biota that can be cultivated in mangrove areas using a silvofishery system, one of which is mangrove crab (Scylla olivacea). The research was carried out in the mangrove area of ​​Mandalle Village, Mandalle District, Pangkajene and Islands Regency, South Sulawesi Province. The test animal used was a male mangrove crab (S. olivacea) weighing 146–168 g which was kept in a circular bamboo cage with a diameter of 2.25 m. The results of the Kruskal Wallis analysis show that the moon phase has a significant effect on the absolute growth and daily growth rate of mud crabs, the dark moon phase produces the highest average absolute growth of 14.53 g with a daily growth rate of 0.57%/day. Meanwhile, the full moon phase produced the lowest average absolute growth of 7.82 g with a daily growth rate of 0.32%/day. The results of the Kruskal Wallis analysis showed that differences in lunar phases had no significant effect on the survival of mud crabs.

Abstract

Fish feed is an important factor in aquaculture, where the physical properties of sinking feed affect its efficient use by fish. Waste fish filets have potential as an alternative feed, but farmers have difficulty finding high-quality feed at affordable prices. This study aims to determine the physical properties of feed with the addition of fermented fish filet waste flour (TLFIF). The method used was a completely randomized design (CRD) with 5 treatments and 3 replicates: P0 (control, without TLFIF), P1 (10% TLFIF), P2 (20% TLFIF), P3 (30% TLFIF), and P4 (40% TLFIF). Parameters observed included: appearance test, aroma, texture, durability test, homogeneity test, and feed sinking speed test. Data were analyzed using analysis of variance (ANOVA) and descriptive analysis. The best TLFIF addition research results were found in the 10% treatment (P1), which had a durability of 98.80%, homogeneity of 42.67%, and a sinking speed of 7.15 seconds/20 cm. The feed's appearance is light brown in color, cylindrical in shape, and fairly uniform in size, with a dense, fibrous texture, a slightly rough surface, and a slight fermentation aroma.
