Ultrastructural, molecular and haemato-immunological changes: Multifaceted toxicological effects of microcystin-LR in rohu, Labeo rohita.

No water body is resilient to afflicts of algal bloom, if goes unmanaged. With the increasing trend of intensification, eutrophication and climate change, Labeo rohita (rohu) is highly anticipated to suffer from the deleterious effects of bloom and eventually its toxins. A comprehensive study was conducted to understand the toxicopathological effects of microcystin-LR (MC-LR) in rohu following intraperitoneal injection of 96 h-LD dose i.

Effect of orally administered azadirachtin on non-specific immune parameters of goldfish Carassius auratus (Linn. 1758) and resistance against Aeromonas hydrophila.

Modulation of the immune responses using active bio-ingredients as a possible prophylaxis measure has been novel prospect for aquaculture. The present study evaluated the effects of azadirachtin EC 25% on non-specific immune responses in goldfish Carassius auratus and resistance against pathogenic bacteria Aeromonas hydrophila. The experimental trial for effects of azadirachtin on immuno-haematoloical parameters in goldfish was conducted by feeding the various levels of azadirachtin as control T(0) (without azadirachtin), T(1) (0.

Effect of azadirachtin on haematological and biochemical parameters of Argulus-infested goldfish Carassius auratus (Linn. 1758).

Argulosis hampers aquaculture production and alters the host physiology and growth. Azadirachtin is recognized as a potential antiparasitic agent against Argulus sp. The present study aimed to investigate the effect of different concentration of azadirachtin solution on haematological and serum biochemical parameters of Argulus-infested goldfish Carassius auratus.

Antiparasitic efficacy of piperine against Argulus spp. on Carassius auratus (Linn. 1758): in vitro and in vivo study.

Argulus are common aquatic ectoparasites that create one of the major threats to aquaculture due to absence of suitable therapy. Piperine, a bioactive component of Piper longum, has medicinal properties and acts as anti-inflammatory, antibacterial, and antifungal, considering eco-friendliness and cost-effectiveness. The present study aimed to evaluate antiparasitic effect of piperine against an ectoparasite Argulus spp.

In vitro and in vivo antiparasitic activity of Azadirachtin against Argulus spp. in Carassius auratus (Linn. 1758).

Argulus is one of the most common and predominant ectoparasites which cause serious parasitic disease and is a potent carrier of viruses and bacteria in the ornamental fish industry. In recent years, organic (herbs)-based medicines are widely used to cure the disease, and neem (Sarbaroganibarini) medicine is very popular and effective throughout the world. The present study was conducted to find the effects of Azadirachtin against Argulus spp.
