Weeds cause a decrease in the quantity and quality of agricultural production and economic damage to producers. The prolonged use of synthetic pesticides causes problems of environmental pollution, the possible alteration of agricultural products and problems for human health. For this reason, the scientific community's search for products of natural origin, which are biodegradable, safe for human health and can act as valid alternatives to traditional herbicides, is growing.

Article Synopsis
- Impact on Aquatic Ecosystems
- : Acenaphthene, a polycyclic aromatic hydrocarbon (PAH), poses a harm to aquatic life, particularly affecting organisms like benthic invertebrates including Tubifex tubifex, through sublethal acute toxicity and chronic exposure effects.
- Behavioral and Histopathological Changes
- : Exposure to high concentrations of acenaphthene led to noticeable behavioral changes in Tubifex, such as clumping and secretion of mucus, alongside significant histopathological effects like inflammation and abnormal tissue growth after prolonged exposure.
- Oxidative Stress and Sensitivity Analysis
- : The study observed increased levels of antioxidant enzymes and markers of oxidative stress in response to
Characterization of four novel actinospore types of fish parasitic myxozoans and the occurrence of and from fish farms of Hungary.

Six distinct actinospore types were identified in the intestinal epithelium of oligochaetes collected from the Szigetbecse and Makád fish farms of Ráckeve Danube Arm Fishing Association, in Hungary. Four new types: triactinomyxon type, raabeia type, aurantiactinomyxon type 1, and aurantiactinomyxon type 2, were described morphologically and molecularly from three invertebrate host species: , and . The 18S ribosomal DNA (rDNA) analysis revealed that these new types of actinospores did not match any myxospore sequences available in GenBank.

Article Synopsis
- Pharmaceuticals, particularly sertraline, pose a risk to aquatic ecosystems as they can remain biologically active when entering the environment and affect non-target organisms.
- Chronic exposure to sediment-associated sertraline significantly reduces survival and growth rates in the oligochaete worm Tubifex tubifex, especially at higher concentrations.
- The study shows that while low concentrations of sertraline affect growth but not reproduction, higher concentrations force worms to use more energy for maintenance, thereby negatively impacting their reproductive output and suggesting a trade-off among survival, growth, and reproduction.
Effect of Different Opening Diet on the Growth, the Structure of the Digestive Tract and Digestive Enzyme Activity of Larval and Juvenile .

One of the crucial factors influencing the growth and viability of larvae and juveniles is their opening diets. The objective of this study was to identify suitable initial feed options for larvae and juveniles. A total of 1200 newly hatched with an average weight of 18.
