ALPHA JECT® micro 2000

ALPHA JECT® micro 2000 is an innovative microdose divalent oil-based vaccine that contains the inactivated bacterial species Listonella anguillarum (01) and Photobacterium damsela subsp. piscicida. It is used for injection vaccination via automated or manual vaccination. 

Fish Species

ALPHA JECT® micro 2000 is designed exclusively for the increased protection of farmed sea bass from vibriosis that is caused by Listonella anguillarum (serotype 01) and pasteurellosis (also described as photobacteriosis) caused by Photobacterium damsela subsp. piscicida.

Unique Benefits

ALPHA JECT® micro 2000 is designed with lower/micro dose: 0,05 ml and thus, it can be used for the injection of smaller fish (minimum weight 12 grams). Its advanced technology offers powerful and notably fast immune response. ALPHA JECT® micro 2000 allows for the optimal growth of vaccinated farmed fish. It can be administered with excellent accuracy through the automated vaccination machines. Finally, its new concentrated dose and its special packaging improve the efficiency of logistics and storage.

Mode of Action

ALPHA JECT® micro 2000 acts by stimulating the immune system aiming in the production of specific antibodies in order to increase fish defence against vibriosis and pasteurellosis. It is administered as a preventive measure for the rational management of farmed fish health. When administered before a potential vibriosis or pasteurellosis outbreak, this product modulates fish’s own defence mechanisms in order to decrease the losses associated with the development of such diseases in the farmed fish population.

Duration of Protection

ALPHA JECT® micro 2000 is administered by endoperitoneal injection and protects sea bass until the end of their farming cycle, i.e. until harvest. The long protection duration is due to the use of a non-mineral adjuvant that allows the gradual release of the antigen to the fish’s immune system. The application of a complete vaccination scheme in sea bass that includes the combination of ALPHA DIP® 2000 and ALPHA JECT® micro 2000 guarantees high levels of protection for the entire production cycle.


ALPHA JECT® micro 2000 is made with natural biological ingredients that leave no residues. Therefore it is absolutely safe and environmentally friendly. To eliminate the risk of self-vaccination incidents it is recommended to use needle protection in the case of manual vaccination or to use of the automated vaccination machine. 


Available in 500 ml sac which is equivalent to around 10.000 doses.
