Abstract:
The aim of this study is to preserve the livelihood of the fishermen and to give an alternative livelihood despite the decline of Sardinella tawilis in Lake Taal, Batangas. This study is a mixed method, which employed a survey questionnaire and interview questions to figure out the possible alternative livelihood for their demographic assets and experiences. This study has 40 fishermen respondents from Tulo, Batangas, who have experienced the decline of Sardinella Tawilis. This study seeks to preserve and help the livelihood of the fishermen, to explore components of livelihood programs (poult

Abstract:
The status of fishery resources of Lake Taal – the third largest lake in the Philippines was assessed to provide updated information on the capture fisheries following the Taal Volcano eruption and COVID-19 pandemic in 2020. Using the methodology of the National Stock Assessment Program of NFRDI, this study was conducted from January to December 2021 at 15 fish landing sites around the lake. In addition, interview schedules of 100 fisherfolk respondents from 11 coastal municipalities were also conducted to assess the effect of the volcanic eruption and pandemic on the livelihood of fisherfolk.

Abstract:
As part of the conservation efforts to address the declining population of the only freshwater Sardinella (Family Clupeidae) endemic to Lake Taal, a two-year study was conducted to determine the possible spawning grounds of Sardinella tawilis (Herre, 1927) by identifying the spatial and temporal distribution of its larvae. Fish larval samples were sorted from ichthyoplankton samples collected monthly in selected sampling stations in the lake. The morphologically identified Clupeidae larvae were determined to be S. tawilis genetically. They appeared only during March to May, with maximum abunda

Abstract:
Reproductive biology is important in formulating management interventions for fish stocks. Limits on catch size are established based on the identified size at first sexual maturity of the target fish species, which can be accurately determined through histological analysis of gonads. The study investigated the reproductive characteristics of the endangered Sardinella tawilis and determined the size at first sexual maturity based on histological analysis. Between 2017 and 2018, 312 fish samples with different lengths were collected in Taal Lake's northern and southern basins. The length-weight

Abstract:
The Taal Lake endemic freshwater sardine Sardinella tawilis (Herre, 1927), an important fisheries species, has been recently placed in the Endangered category by the International Union for Conservation of Nature due to its high endemicity and population declines, coupled with potential threats from natural volcanic and geologic events. We examined the survivorship of S. tawilis in short-term ex situ captivity (~ 30 d) and determined water quality parameters that influence survival. Collection, transport, and ex situ captivity trials for a total of 333 S. tawilis individuals were conducted fro

Abstract:
The supply and value chain of the world’s only freshwater sardine, Sardinella tawilis endemic to Taal Lake, were studied from January to December 2016. This study aimed to identify the actors in the value chain, evaluate each actor’s value addition, identify the roles of men and women in the chain, and identify the issues, concerns, and entry points for intervention. Key informant interviews, focus group discussions, and tracer survey interviews were done to gather data. A semi-structured questionnaire was directed to 189 respondents within and outside Taal Lake. The study showed that the tawi
