Romi Novriadi Full Text Available Peningkatan laju produksi perikanan budidaya secara umum berperan penting dalam peningkatan masalah lingkungan dan patogen di beberapa unit produksi budidaya.

In conclusion, the distribution of depik is not seasonally dependent, but more spatially. In contrast, bigger fish was found in deep waters offshore,but with lower abundance. The Rasbora tawarensis is widespread in the lake but most abundant in shallow waters andthe near shore, however, the size is small on average for this area. Sampling was conducted in differentseasons dry and wet season. Two fishing grounds were selected based on information from local fishermen,and a total of 14 fishing sites (seven sites per fishing ground were determined randomly.

Free Download Program Uncharted 3 Hacking Tool. Stratifiedrandom sampling was utilized in this study. Hence, the objective of present study was to evaluate thedistribution patterns (spatial and seasonal distribution based on catch per unit efforts and fish abundance data. Information about distribution patternsis crucially needed in relation to plan better conservation strategies. Muchlisin Full Text Available Depik fish, Rasbora tawarensis is an endemic and threatened species in Lake Laut Tawar (Central Aceh, Indonesia,and the population of depik has been decreased drastically over the last two decades. This species is classified as a group synchronous spawner.

Tawarensis were three times a year and September being the peak of the reproductive season and the female was the predominant sex. Tawarensis can be classified as a group synchronous spawner or a fractional multiple spawner.Ĭonclusion The spawning seasons of R. The ovaries had multiple oocyte size classes at every stage of gonadal development, thus R. Although, a greater proportion of mature male than female was detected during the study, the sex ratio showed that the overall number of female was higher than male. Tawarensis was higher in March, September and December indicating the onset of reproductive seasons, the GSI and oocyte size being directly correlated with gonadal development stages. Results The gonadosomatic index (GSI varied between 6.65 to 18.16 in female and 4.94 to 8.56 for male.

The gonadosomatic index, size composition and sex ratio were assessed.

Methods Monthly sampling was conducted from April 2008 to March 2009 by using selective gillnets. Tawarensis especially on spawning seasons as well as basic information for conservation of the species. Therefore, this study provides a contribution to the knowledge on reproductive biology of R. To date no information on the spawning activities of the fish are available. Unfortunately, its status is regarded as critical endangered with populations decreasing in recent years.
